Foreword

Foreword from the Executive Board ^

by Marc Baumgartner, President and CEO IFATCA

Air traffic controllers our most important asset …! Last March, Patrick Forrey, the President of our USA Member Association, gave a remarkable testimony in front of the US Transportation and Infrastructure Subcommittee on Aviation, on the FAA safety and operational programs’ review.1

NATCA Testimony What I find remarkable in the testimony, are the statements where Pat calls for a greater involvement of air traffic controllers in the design and creation of the future ATM system of the USA. He mentions as well, very good examples from the past where this collaboration between management, government, air traffic controllers and other aviation stakeholders worked for the benefit for the safe and efficient air transport system. I guess we are again, at a global level, at a crossroads with trying to create a future ATM system which is fit for the future challenges where as in the past we experienced tension between the various actors – in particular the ATM providers and their most important asset (staff).2 One could actually believe that it is recognised that working together in the aviation sector is the way ahead to improve the ATM system, as initiatives like ATMCP at the global level and NGATS and SESAR at the regional level discuss this.

Communication Therefore it is important that you the representatives of the profession of an air traffic controller at the national and/or international level are able to understand, translate and communicate to non-controllers what it is all about. What makes you proud and what makes you so passionate about your profession. IFATCA has always tried to assist aviation with the professional and technical input of our experts and delegates. Lately we are very pleased that the efforts of IFATCA again show some results. Our experts and representatives at all levels, national, trans-

national and international are being associated and involved at the outset through development and adoption of our policies which are then taken into the creation of new procedures and/or modifying existing procedures, where we are developing a better understanding of our needs, and become sponsors of a safer and more efficient ATM system.

IFATCA’S Successes I would like to highlight a few recent examples where IFATCA has been successful at the highest level. Our experts have worked on some of the ICAO Assembly 35 decisions (in particular on Human Factors and the Global Concept of Operations). The newly endorsed changes of the PANS – ATM where our representatives contributed in the drafting, and of course in the more trans-national issues in Europe where significant input is being given to the ongoing Single European Sky developments.

Statement on ATM Future On the 15th of March IFATCA has published its global statement on the future of ATM which has received notable positive feedback. The Executive Board is convinced that we have to continue our efforts to contribute to the challenges of aviation with our professional and technical voice. But not only at the global or trans-national level can the expertise of IFATCA or of the professionals be of benefit. Involving operational personnel from the outset of developing new systems becomes more and more important as we are slowly experiencing the first real steps of automation in ATM. This development will mean that the human will rely more frequently on automation to assist in doing the job. It is therefore paramount that the operators are associated in the work from inception, design, simulation and implementation of new systems.

Workaround Failures Too many times with new systems (not necessarily new automation) our members have experienced, that due to the failures and flaws within the system they have had to find workarounds to make the system perform in a manner that maintained operability, safety and efficiency. This is frustrating as on many occasions these workarounds could have been avoided had the staff been involved in the development. Instead the staff are left demoralized and frustrated with the inevitable building of tension and resentment of change. Professionals like air traffic controllers can be justifiably proud of their every day efforts, however in the current fast-changing environment it is just not enough only to do the basic job. There is a need that all controllers become involved and display their knowledge to influence their future.

Recognition However there is of course a negative side to this argument where the basic needs of the controller are denied and the staff are demotivated and lack pride when they are not recognized as the professional which they are. This is the most important fight for them. We see it currently ongoing in Brazil and Argentina or in all the ASECNA member countries. In other countries it is about involving the controllers in fundamental decision making which will shape the future of aviation in the respective countries. Pat Forrey’s testimony to the US Congress says it all. I invite you all to read the IFATCA Statement on the future global of ATM, as it gives a lot of guidance on how as a real stakeholder we as representatives of a highly skilled profession can assist the aviation community with our knowledge, expertise and vision. In countries where controllers are and were associated in all the changes in the working environment, national ATM and aviation policy, the results have shown the efforts to have been repaid a million times over in improved procedures, functional ATM equipment and happy customers from a staff perspective, the airlines and the traveling public at large. ^ 1

Editorial

Editorial 30 years ago: Tenerife Philippe Domogala, ^ by Editor The worldâ&#x20AC;&#x2122;s worst air disaster occurred 30 years ago, on 27 March 1977, 583 people died, 70 survived. The story is well known; massive diversions due terrorist bomb in destination airport, misunderstandings about take off or airway clearance, misunderstanding about a taxi-way exit, a sudden 300m RVR, haste and a crossed transmission. Many small things ending up in a tragedy. A sad day for us all to remember, and learn from. Tenerife brought some procedural R/T changes and more awareness. It re-enforced the need for CRM in the cockpits. Two B747s colliding was a nightmare predicted at the time, as the 747 was introduced with its ability to carry 350 passengers. The 747 (introduced in 1969) replaced the DC8 and B707, which carried between 150 and 200 passengers. This increase in size was the subject of many discussions at the time. Such as: our runways are not made for this, our airports will not be able to cope, imagine 3 or 4 747s arriving at the

same time, and the wake turbulence they will generate, etc. In reality, everything went fine, and the 747 was and still is one of the safest aircraft. It was involved later in a few accidents, but rarely due to its concept. Human errors are mostly at the root of accidents, back then, and still today. In fact it is amazing (if I may use that term) that the percentage of human errors in accidents is still steady at around 75-80% in aviation, since the 1960s. The number of accidents decreased dramatically, but the human factor ratio versus technical/ mechanical remained the same. Curiously the percentage does not differ much between commercial and private pilots, despite the huge difference in training.

Now in 2007, where the largest airliner of this century, the A380 will enter passenger service with the possibility to carry up to 850 passengers! And we see the same debate as back in 1969 about size, wake turbulence, parking, runway strength, etc. There is an article in this issue about this. Every controller that will soon have a 380 on his frequency should read it. Talking about human factors and automation, you will find also an article about working without strips. If you still use them, a must read, because believe me, those tiny pieces of paper are going to be history for everybody very soon. It is all about trusting technology, similar to Airbus and Boeing pilots (People forget that the 777 and the coming 787 are using almost the same advanced automation technology as Airbus.) So you can dream about your paper strips and your telephones, like pilots dreamt about their flight engineers and their cable-driven control columns, because they will all be gone for good very soon. Enjoy reading!

4 IFATCA 2007 Conference

Istanbul, Where East meets West IFATCA 2007 Conference in Istanbul

Report by Philippe Domogala and Helena Sjöström

Istanbul A fascinating city of 18 million people, full of history and the border between Orient and Occident, between Asia and Europe. This was the setting of the 46th IFATCA annual conference in April, held in the Lutfi Kurdar Congress Hall, a large conference centre in the heart of the city. The Turkish controllers proved to be very dedicated hosts and the debates were interesting to follow.

Opening Speech by Minister of Transport Mr Binali Yildrim, Turkish Minister of Transport, explained the impressive modernization plans for Turkey but also pointed out that in a new system, the human dimension is far more important than the technical. “We should invest more in human beings than in infrastructure. Also in safety, since most accidents in

aviation relate to human factors causes. Socialand training issues are more important than hardware and they need to be improved.” He also said that we should see the forthcoming ICAO level 4 English requirement not as a threat but rather as a chance for improvement. His speech was interesting and surely pleased our Turkish colleagues, but was it a firm policy statement or just a public relations speech? Time will tell of course, but The Controller Magazine intends to be there to verify if things have indeed improved, for example in three years time, when the new Ankara ACC will come into operation.

Technical Discussions The technical debates in committee B concentrated on a few hot topics. Converging Runways Operations (CROPS), which includes simultaneous operations of intersecting and converging runways and the infamous LAHSO (Land And Hold Short Operations), used in the USA. IFATCA opposes LAHSO as there are still many problems associated with this procedure. There were also long discussions about ASAS (Airborne Separation Assistance System), on the boundary of responsibilities between pilot and controller at any given time.

“We should invest more in human beings than in infrastructure: Mr Binali Yildrim, Turkish Minister of Transport.

ADS (Automatic Dependant Surveillance) was the subject of a very intense debate and resulted in a long series of recommendations. Finally, CPDLC (Controller Pilot Data Link Communications) was discussed extensively and a clear policy was passed: Implementation of CPDLC must be in full compliance with ICAO ATN. Non-compliant aircraft (e.g. FANS) can be accommodated in remote or oceanic airspace. In high-density airspace, FANS aircraft shall be handled via voice R/T for safety reasons.

Professional and Legal Discussions Committees B and C had one day of combined sessions in which, amongst others, the very hot issues of “Visual observation in a control tower environment” and “Future ATM concepts for the provision of Aerodrome Control Service” were covered. The Visual observation working paper was presented by PLC (Professional and Legal Committee) and the Future ATM concepts by TOC (Technical and Operations Committee). The proposed policy on Visual observation stated

4 IFATCA 2007 Conference that “watch shall be maintained by visual observation, augmented by radar or other approved control systems”. The proposed Future ATM concepts policy said that the controller “shall be provided with at least the same level of surveillance as currently provided by visual observation”. Although these two policies may appear to be conflicting, the delegates passed the proposed policy on both issues. This can be seen as wanting to ensure and maintain a high level of safety in the present but at the same time not closing the door to the future. Committee C, expertly chaired by Bert Ruitenberg, had good and productive discussions and finished its work on schedule every day. Among the many topics was the IFATCA Information Handbook. The handbook contains information about work conditions, salary, pension etc. of all member associations and is very useful. However, it is difficult to get the MAs to fill out the questionnaire and thus the handbook is currently outdated. If the information is not given by the MAs, the handbook will be discontinued, which would be a pity. Stress management was another topic. New policy was passed stating that “professional critical incident support services should be made available to controllers involved in ATC incidents/ accidents and any other occurrences that have potential to create critical stress reactions influencing the controllers performance”. Other working papers related to: new IFATCA training policy (only editorial changes); IFATCA policy on accident and incident investigation; legal issues on paperless/stripless environment and policy on hours of work.

Brazil Marc Baumgartner, President of IFATCA, made a poignant presentation on the situation of the controllers in Brazil, especially after the accident last September (collision between a Boeing 737 and an Embraer Legacy jet over the Amazon, extensively covered in the last issue of the Controller).

China RVSM implementation in Chinese airspace next November is expected to cause major difficulties, as it will be a unique metric FL system. This is likely to have a have a vast impact on at least ten surrounding countries’ FIRs.

Nepal Controllers in Kathmandu that have continuously reported R/T communications difficulties after a system break down of ATC equipments in August 2004.This issue is causing them enormous stress and despite many reports the situation is still not resolved today.

Europe IMPACT of FABs (Functional Airspace Blocks): There are too many FAB-initiatives, which are not coordinated. Some states find themselves in two, even three different FABs, while some others could declare their own state an FAB (e.g. Norway). Turkey is also not part of any FAB but said that since large parts of the Mediterranean and the Black sea are high seas (i.e. not belonging to one particular state) ICAO should be involved and any change in FIR delineation should be subject to ICAO agreements. Many member associations see the institutional problems with regard to military airspace as a major problem.

Memorandum of Understanding between ITF and IFATCA The presidents of IFATCA and ITF (International Transport Workers’ Federation) have signed an agreement, with the intent of having a larger and stronger united voice when dealing with international bodies on controllers’ issues. Both organizations will endeavour to work together and produce common positions on issues of mutual concern. While ITF recognizes IFATCA’s expertise in professional and technical matters, IFATCA also recognizes ITF on social and trade union is-

sues. The two organizations will from now on endeavour to coordinate their statements, especially regarding positions taken in ICAO and other international organizations.

Workshop on ICAO Language Requirements In the optional workshop on English language requirements, Adrian Enright, project leader of ELPAC at Eurocontrol, confirmed the date March 5th 2008 as being the only valid date for the implementation of the English language requirements. There seems to be a misunderstanding regarding the date and beliefs that the EU has published another, later date, which is not the case. Adrian Enright reported that the ELPAC test, produced by Eurocontrol, is delayed but will be ready in July. Several member associations said that their ANSP has not started or has not gotten very far with preparations for the language requirements. There is great concern that many controllers are presently not qualified for the level 4 requirements and many MAs were asking IFATCA for help.

STAFF SHORTAGES IN EUROPE Dominating subjects at the informal European Regional Meeting held during Conference were the increase in traffic, the introduction of new technologies and equipment and the lack of air traffic controllers. Whilst few countries are sufficiently staffed, the majority of our members declare shortages between 10% and 30%, resulting in a lack of ca. 1000 controllers in the region (32 of 45 associations participated in this survey). Salary and employment contract negotiations keep several associations busy. Other topics discussed were the lack of information about legal repercussions in case of incident/accidents and the ongoing privatization of ANSPs. The diversity of uncoordinated Functional Airspace Block initiatives is striking but at the same time worrying, as benefits appear unclear. The suspicion that economical interests of the states rather than improved handling of air traffic are the drivers of these undertakings is prevailing amongst the member associations. Several states have experienced difficulties with the compliance of EC laws, such as the required separation of service provision from regulation.

4 IFATCA 2007 Conference However, the Federation cannot do much more than continue its efforts to urge the ANSPs to comply with the ICAO standards, and support the MAs in their further attempts to make the ANSPs and the regulators realize that time is running out.

[some] ANSP has not started or has not gotten very far with preparations for the language requirements.

4 Opening ceremony.

Closing Speech by Director General of Eurocontrol Mr Victor Aguado, Director General of Eurocontrol, closed the conference with a keynote speech in which he painted a rather impressive and good picture of European ATM performance in the last years. He said four years ago, airlines where presenting an apocalyptic view of the future but last year, delays were reduced by 75 % to one minute per flight (an economically acceptable figure). Route charges fell by 13 % over three years and this despite an actual traffic increase of 4 to 5 % per annum. On the safety side, the number of ATM-related incidents is steadily falling and there has been no ATM-related accident in the last four years. To not be resting on our laurels but making sure we can improve or maintain our safety levels, is the true challenge, he closed.

Next Conference The 2008 IFATCA Conference will be in Arusha, Tanzania on March 10 – 14 2008 The 2009 IFATCA Conference will be in Dubrovnik, Croatia on April 20 – 24 2009 ^

Interview Murat Ozdil, President Organising Committee from the Turkish Air Traffic Controllers Association

We are currently short of staff by 25-30% and traffic raised last year by 25%. Philippe: Are you satisfied with the conference? Murat: We had 520 delegates, and while we expected between 600 and 700, they were from 89 different countries and 80 different Controllers associations were represented. This was higher than in previous conferences, so we are happy. It was also an opportunity for us to show the world our hospitality and our culture. It was an honor to carry the Flag of Turkey. Ph: will this conference change something for the Turkish controllers? M: It is too early to tell. But on the political side, we had the presence of the Minister of Transport and Communications

The Challenge for Turkish Controllers the first day, and he was impressed, so I guess there will be a positive attitude in the future regarding the status of controllers in Turkey. Ph: 2 years ago controllers got a new statute in Turkey, Are you pleased with it and are salaries and working conditions OK? M: The new statute was a huge improvement, Our salaries are good compared to the general population in Turkey, but we are still far below compared to our neighbors. Ph: You will also shortly receive a brand new ATS system. M: Yes, build by SELEX (Italy) It should be operational in 3 years. It is part of a complete change, as we will unite our country into a single FIR and a single ACC that will be in Ankara. Istanbul will only remain as an Approach unit.

Ph: were you involved in the development of this new system? M: Not directly but indirectly, as former Association EB Members are working on the project and we have feedback from involved colleagues. Ph: What is today the biggest challenge for Turkish Air traffic controllers? M: The number of controllers versus the traffic increase: We are currently short of staff by 2530% and traffic raised last year by 25% domestically and 9% in overflights. A few years ago some traffic forecast estimates were made, but in 2006 were already reached the same figures that were predicted for 2015… We also will get shortly a separation of the ANSP from the Airport Authority to create an autonomous body. A draft law on this separation is expected to be approved by our Parliament soon. That issue is important as it will affect our future professional life. ^

Turkey Statistics as published by the Ministry of transport: Civil aviation growth: +30% in 2006. Between 2002 and 2006 (4 years) number of passengers increased 239% domestically and 31% internationally. Traffic movements over the same period +185% domestic, +31% international, overflights +42%, making an total average traffic increase of 72% .

YOU’D BE SURPRISED WHERE YOU FIND US

As airspace gets more crowded, you’ll find Thales taking control. ATM systems face the same challenge worldwide: economic growth means more air traffic, putting dangerous pressure on existing systems. Thales is the safe choice for future development. We can take on prime contractorship and deliver complete turnkey solutions, gate to gate. We already control the airspace in 180 countries: our EUROCAT ATM system is the industry standard. In technology, we lead the way with Mode S radars and Automatic Dependant Surveillance-Broadcast (ADS-B). In European initiatives we’re partners in the Single European Sky (Sesar) and Galileo satellite programmes.

Fully equipped for the present; already planning for the future. If you’re looking for the safest route forwards, call Thales.

4 Future

Air Transport and the Energy Challenge ^ by Daniel Casanova The «Académie Nationale de l’Air et de l’Espace» was host in Toulouse, from November 30th to December 1st, to an international colloquium on this issue.

Nuclear propulsion has no future for air transport, except maybe if a “new” fission concept can be developed

The Problem The problem facing air transport in the 21st century is, more than anywhere else : • Energy density is the key economic concept. • Consequently, hydrogen should never be able to replace liquid hydrocarbon for automotive transportation (estimations in liquefied H2 usage). • However, hydrogen could replace jet fuel, whether ex-refinery or synthetic, for aviation (possibility to use liquefied H2). • This possibility would become more probable if carbon emission costs became higher than anticipated today, say above 100$/ton of CO2 in the present $ terms. For the aviation industry, the choice between liquid H2 and/or synthetic kerosene should occur between 2020 and 2030 in order to define the new generation of airplanes to be constructed from 2040-2050.

Which Propulsion System and Aircraft for the MID-21st Century? For Rolls Royce there are three ways: • Evolutionary option on actual engine (innovative powerplant noise, drag, weight; Moreelectric technology, including embedded

4 X48B research model.

(IP spool) generator, and power transfer technology) • Radical Options: Advanced cycles to alleviate thermal efficiency constraints (Intercooled cycle to enable ultra-high overall pressure ratio, up to 5% sfc improvement, NOx reduction through reduced compressor discharge temperature) and Novel LP system architectures to alleviate propulsive efficiency constraints (Open rotor 10-15% sfc improvement) • Revolutionary options: Change to propulsion system most likely to be driven by radical change to energy source and/or aircraft architecture

Improving Existing Fuel Efficiency Airbus vision is to improve operational fuel efficiency. Airbus gives two examples; 5 minutes saving of one engine use with an A320 operating 5 missions per day offers a potential saving of 50 t fuel per year and up to 300 000 t. fuel saving yearly are planned in EU Domestic airspace thanks to implementation of RVSM above 29000 ft. The avoidance of the contrails/cirrus formation areas may be envisaged: Flying lower (However negative impact on fuel burn, thus CO2 emissions) or Adapting Flight Path to weather (Significant impact on ATC). The potential solution is Bio fuels. But they have to face critical issues: • Compatibility and efficiency of various bio fuels • Affordability (Currently around 130/150 $/barrel) • Availability (à15% of cultivable lands for aviation needs in 2025) They could be used as complement to oil kerosene either as additives or partial substitute.

4 Future management. On this point, Boeing hopes for accurate paths to improve airspace capacity and efficiency, like options to sequencing, reducing inter-arrival spacing, improved reliability in poor weather and more efficient routing via path of specified width. Continuous descent approach procedure is a solution for the noise.

Do alternative Energies Exist? • Nuclear energy is characterized by a very high power density, Nuclear propulsion does not produce greenhouse gases directly and the reserves of fissile materials are more important than those of the chemical fossil resources; the estimation of reserves is dependent on the selected nuclear technology. But there are societal drawbacks: Nuclear energy is weakly accepted by a large number of countries. • The bio-fuels are currently in vogue, the priority application is the road transport, the specificity of air transport being poorly taken into account however air transport is increasing faster than road transport and air transport activity follows longer cycles. Specifications of a biofuel for transport aviation have been deduced from those of the military kerosene and from the ICAO standards. The objective was to evaluate if a biofuel can be used on existing aircraft/engines or on those in development, without any impact on their performance. Only the synthetic fuel produced by the FischerTropsch process from vegetal biomass appears to meet the specifications, with a possible advantage regarding the pollutant emissions (sulphur compounds, soot). The cost of such a synthetic fuel is not accurately known but, as for all the emerging technologies, is probably high.

formance is potentially interesting for its efficiency but with its current characteristics, especially for the specific power and the reliability, it cannot compete with the conventional aero-engines. If an improvement of factor 10 is achieved on stack specific power, then the issue could be revisited. The fuel cell aircraft is a type of cryoplane and therefore it depends on the availability of massive amounts of hydrogen. A hybrid concept could be proposed for a long range aircraft: a fuel cell working at its maximum efficiency and sized for cruise and conventional aero-engines for take-off, working at idle at cruise.

✈ Fuselage LH2 Tanks, Blended Wing Body, Continuous Moldline Flaps, Distributed LH2 Propulsion, and Forward and Aft Noise Shielding Air Traffic Control

In conclusion, Nuclear propulsion has no future for air transport, except maybe if a “new“ fission concept can be developed. The synthetic biofuel produced from biomass is technically attractive in the medium term. Fuel cell propulsion technology must be improved to be considered for a long term vision.

About ATM, Eurocontrol presented the SESAR program to improve flight efficiency. If we could remove delays in Europe, the problem will not be that acute. (15 million minutes not necessary, 1,5 B$ of wasted operational costs, fuel and more than 1 Mt of CO2 emitted)

The Research Today.

If we try a synthesis, the main objectives for next twenty years are reducing weight and drag for new aircraft, use bio-fuel or liquid hydrogen and improve the ATC system. This last objective will stay very difficult in Europe without a common government with a common ATC system. It’s not only a question of technologies, but a human factors question! European ATC system has to advance with the controllers.^

• The fuel cell is an efficient way for directly converting the chemical energy to electrical energy ; electrical power can feed motors which drive fans. In this concept, the “energy conversion” function is decoupled from the “thrust production“ function. • Application of fuel cells to aerial vehicles is currently limited to demonstrations on small aircraft or UAV‘s and to APU‘s. The main advantage of a fuel cell is its potential of efficiency which cannot be achieved by conventional engines. Fuel cells are considered in connection with the use of hydrogen as fuel, for future emissionless aircraft (NASA‘s Alternate Energy Revolution programme); reforming of an on-board hydrocarbon has no advantage for the emissions and is very heavy.

4 Stripless Systems

Working without Strips Automating ATM in the controller‘s best interests Yves Le Roux ^ by Programme Manager, Skyguide

Detecting a conflict without strips.

The increasing automation of air traffic management systems may be an essential response to the further growth predicted in air traffic volumes. But whatever form and extent such automation takes, it must remain firmly in the interests of the air traffic controller, by meeting their needs as effectively as possible. This, at least, is the philosophy adopted by Skyguide for its “stripless“ air traffic management system, which has been in use for the western area of its UAC since the end of 2005. The new system has been developed by and for the company‘s controllers – which may explain their satisfaction with this new worktool, as well as the ease with which they have adapted to this change in their working processes. Far from being just an electronic version of the traditional paper strips, Skyguide‘s new system has brought important innovations to the controllers‘ planning, scanning and conflict detection activities. And if all these changes have been welcomed by the 80-odd Geneva-based controllers who have been providing fully-digitised management of the traffic in Skyguide‘s UAC West since December 2005, such acceptance is due in no small part to a project approach that has given them a large say in the system‘s development.

Example of a received coordination.

Example of an accepted coordination.

Active participation in a step-by-step approach With its clear aim of not merely producing a screen display of “electronic“ paper strips, Skyguide‘s stripless project reappraised how flight data can best be handled and presented in line with the controller‘s working logic. This meant taking a close look at how controllers used the paper strip details, asking questions such as: What mental processes do they employ? What functions do they use? What new tools may they need? And how can all this be presented on the screen with the safety, efficiency and user-friendliness required? Consideration also had to be given to how best to put the new system into practice. Experience has shown that a “Big Bang“ ap-

proach to technological innovations often produces far-from-favourable results. If some such transitions do succeed, that success is often only achieved with major investment or generous lead times, or with the less-than-total acceptance of the users concerned. In view of this, it was decided to adopt the new stripless system gradually, in a series of subprojects or functional “batches“. This progressive and dynamic approach not only helped raise user acceptance; it also greatly facilitated the requisite training of the operations staff involved. None of these processes would have been possible, however, without the active involvement of working controllers throughout the project‘s development, from the first preliminary analyses through to the new system‘s implementation. Similarly, the project‘s success could not have been achieved without controllers‘ tolerance and acceptance of the sometimes substantial inconveniences at certain transition points along the way.

New functions for the controller‘s benefit The stripless system has not changed the controller‘s basic working principles, their overall role or the responsibilities they bear. Traditional air traffic management tasks – such as telephone coordination, traffic planning and integration, strip scanning and strip marking – have only been simplified by introducing tools to permit electronic coordination, determine exit parameters, detect conflicts, filter flights for greater visual clarity and plan and acquire information (see the examples below). But all these tools have been developed solely to assist the controllers, who retain their central role. The issue of whether to offer the new aids as support tools or control tools was one that generated extensive discussion, however – as it is sure to do in the future, too.

Beating the blank screen The question of what would happen if the system malfunctioned or failed is one that has occupied the stripless project throughout its evolution. Procedures and system elements have been adapted to cover the many forms

THE

CONTROLLER

4 Stripless Systems

Assistance in determining exit parameters The new system‘s Exit Condition Automation Tool (ECAT) alerts the planning controllers for each sector to any potential conflicts that are detected by the system at the points where the traffic being handled will leave the control centre‘s airspace. In this example, ECAT is flagging an exit conflict for flights EZS1094 and RYR973G, which both have an XFL of 280 at the Dijon exit point (“DJL“), and is suggesting resolving the conflict by assigning Flight Level 260 to one of these flights.

4 Conflict detection The new system‘s conflict detection tools – the Horizontal Scanning Tool (HST) and the Dynamic Scanning Tool (DST) – help controllers in the scanning they conduct for their medium-term traffic planning. In the HST display below, a conflict has been detected for flights AZA9F7 and HLF807, which have both been cleared to fly at Flight Level 370. In 6 minutes and 19 seconds, these flights will cross paths with a minimum separation of 8.9 NM.

that a technical malfunction might take. One particular innovation has been the development of a new Emergency Display (EMDIS) screen, which would compensate for the lack of paper strips in the event of a major failure of the principal system.

per movement – partly by enabling the controller to focus solely on the screen, but also thanks to the efficiency of the system‘s human-machine interface. This working comfort has itself translated not only into a tangible increase in performance, but into enhanced safety, too.

Job satisfaction

Leading the way

Results with the new system to date have been convincingly positive. This is confirmed by the controllers, who appreciate the convenience that the new tools provide, and the flexibility with which they can be adapted to any traffic situation and any controller‘s needs. Above all, the new tools have greatly reduced workload

The new stripless approach has prompted Skyguide to be named as a “pioneer“ by Eurocontrol‘s First ATC Support Tools Implementation (FASTI) programme – not only for its tools, but also for the way the whole system has been introduced and assimilated by its controller corps.^

4 Electronic coordination As it is now performed electronically, the coordination between planning controllers and executive controllers within each sector and between sectors can now be effected silently and in real time via the radar screens. All such actions are based on proactive traffic monitoring and suggesting flight levels using a downstream-upstream approach, rather than via upstream-downstream requests. In other words, it is the next or “downstream“ sector in the sequence that will suggest a flight level (possibly with conditions) to the “upstream“ sector, which is currently in contact with the flight or is about to begin managing it.

The new Airbus A380 An Air Traffic Control view Ph oto :A irb

Daniel Casanova ^ by (Controller in Toulouse

Blagnac TWR) The A380 is the largest airliner ever built. The A380 is certificated to carry as many as 853 passengers; however most A380 customers have chosen a three-class configuration with a typical capacity of 500 seats.

The Aircraft Size Using a new generation of engines that can lift the plane‘s 560 Tonnes maximum take-off weight into the air, the aircraft has an excellent runway and climb performance. As amazing as it is for the largest aircraft in the world to take to the air, the A380 faced significant challenges on the ground as well. However airport compatibility was a design requirement from the earliest stage of the programme, keeping changes required at airports to accommodate the A380 to a minimum. To integrate into existing airports, the A380 had to fit the standard airport-docking plan. The plane‘s nearly 80m wingspan meets this requirement by about

A380800 Basic

40 cm. Its outer-most engines, however, would hang just beyond the standard 45m runway width, requiring minor upgrades, i.e. shoulder extensions at many airports. The plane‘s weight will be distributed over 20 landing gear wheels, actually producing less weight per wheel than the 777. The cockpit location, between the main and upper decks, is designed to give pilots a view of the runway and taxiways at the similar height as the A330/340 aircraft and therefore improves manoeuvrability.

Flight Testing During the flight test for certification, the five A 380 flight test aircraft (4 Trent 900 powered and 1 GP7200 powered) have flown a large part of the test program in the Toulouse-Blagnac TMA. The Toulouse Approach Centre provides the ATC services in this TMA. Around 70 civilian controllers plus 10 test and acceptance traffic controllers serve in the centre. For civilian IFR traffic, controllers provides normal ATC services. They also provide tower services and radar control during controller training. Part of the IFR approach room is reserved for CER (a French test and acceptance navigation control center). Blagnac is also a flight test centre with air traffic control officers specialising in CER. These controllers are trained for this specific role under the authority of DGA (French Defense Procurement Agency). The CER is used by the French flight test center to conduct flight tests for aircraft and navigation system tests as well as acceptance flights.

The CER controllers integrates these test flights into French airspace with coordination from the SNA (French ATC provider) controllers.

Experience With over 3300 flight hours of A380 flying to date, the controllers unit of Toulouse-Blagnac has gained extensive experience on the new aircraft. From the point of view of performance the A380 is very easy to integrate in a radar vectoring approach. The speed range of the A380 provides good opportunity to the controllers to accommodate it with other aircraft, regardless of their size or speed. According to airline crew who have flown the A380, it is as manoeuvrable as an A319! Even at maximum takeoff weight, the A380 can directly reach the initial cruising altitude of FL350 in 28 minutes and 204 nautical miles, and cruise at 0.85 Mach. Runway performance and occupancy times are also very good. During the recent A380 route proving flights to the United States, the A380 landed at JFK at very close to maximum landing weight, yet spent less than one minute on the runway after touchdown. On the ground, the Blagnac taxiways intersecting at 90° are no problem for the A380, and following certification by the EASA, there are no operating restriction on the 45-meter wide runways. A useful aid for A380 crews is an on-board taxi camera that provides an external view of the position of both the nose and the main gear wheels.

There have been many questions about A380 wake turbulence. Airbus has accordingly performed an unprecedented amount of wind tunnel and flight tests. In November 2005, with the first international flights of the A380 imminent as part of the flight test programme, ICAO issued highly conservative interim guidance on wake vortex separations based on the very limited data available at that time. For approach, the guidance stated that any aircraft following the A380 should maintain a 10nm separation. In order to replace the very restrictive November 2005 Interim Guidance before the start of A380 Technical Route Proving, ICAO agreed to issue a new State Letter. This new set of rules was based on the recommendations coming from the A380 Wake Vortex Steering group, a group consisting of the FAA, Eurocontrol, JAA-Ops and Airbus, with ICAO as an observer. Several flight tests and simulation were conducted to produce these recommendations. This letter was issued on 9th October 2006. In the new State Letter ICAO classified the A380 as a member of the Heavy aircraft category, but with additional separation between it and following aircraft for the arrival and departure phases of flight. In all other respects the A380 would be treated like any other Heavy aircraft. The Toulouse Blagnac controllers currently uses the following set of separation rules which reflect the October 2006 State Letter.

The A380 is certificated to carry as many as 853 passengers Of course there is sometimes a problem of perception. A pilot might suffer some turbulence (due to wind or temperature). If he notices an A380 30 nm ahead, he will immediately think that it was produced by the double-decker! So we think it is a good idea to keep other pilots informed on the location of the A380 in order to avoid such perception problems. The question that many in the industry are now asking is: what about the future? Following the unique testing that resulted in the current A380 separation standards, it has been acknowledged by the ICAO and the A380 wake vortex steering

group that further flight testing and early inservice experience may assist in justifying further reductions in separation times and distances for aircraft following an A380. Airbus already has further flight testing on the A380 agenda to support the development of revised entry into service separation standards. So the answer to the question is: watch this space.

First Flight The author has flown on the A380, and it was an exciting experience. The cockpit is very spacious and uses the same cockpit philosophy and operating procedures as the A320 and A330/A340 families, while also benefiting from advances in technology for displays, flight management systems and navigation. The growing numbers of pilots already qualified on Airbus fly-by-wire aircraft will feel right at home on the A380 flight deck. The new Airbus airliner uses the same cockpit philosophy and operating procedures as the A320 and A330/A340 Families, while also benefiting from advances in technology for displays, flight management systems and navigation. The A380 cockpit will have eight large identical, interactive displays on the

main instrument panel, with cursor control provided through a track-ball. The displays provide a much larger screen area with clearer presentations. An optional dual HUD (headup display) installation can further increase pilot situational awareness, particularly during the approach and landing phases. Feedback from passengers who have flown on the A380 is that the aircraft redefines the meaning of comfort for everyone onboard, whether they are premium customers in first and business class, or leisure travellers in the economy cabin. Both passenger cabins are wider than the largest airliner in service today, offering the possibility for wider seats and aisles, along with more open spaces and access to optional passenger amenities such as business centers and rest areas. The A380â&#x20AC;&#x2122;s cabin arrangement is flexible and is intended to allow airlines to differentiate their products and develop solutions for all potential market mixes. Some operators might, for example, choose to seat their first and business class passengers on the upper deck providing a corporate jet-like environment for these clients while configuring the A380â&#x20AC;&#x2122;s main deck for an all-Economy layout. Regardless of the parameter by which it is measured, it is sure that with the A380, Airbus has embraced the future. From a controllerâ&#x20AC;&#x2122;s perspective, it is an aircraft that is very easy to guide under radar control despite its size. Regarding wake turbulence, Airbus has chosen to test in flight, with real wake encounters, to answer the question with real facts and data. This approach is already bringing dividends, not only for the A380, and is a commendable approach that any other commercial aircraft manufacturer should adopt.^

John Levesley ^ by (President GATCO, UK)

The Mosaic stand [was] promoting a public service view of European ATC. Controllers might find their view quite fascinating.

In recent years ATC Maastricht has become one of the major international events in the ATC year. It has three aspects; a Conference, an Exhibition and a social opportunity for friends, peers, colleagues and even competitors to meet.

The Exhibition The Exhibition hall had a real buzz to it: lights, action and even music! What particularly caught my eye (and ear) amongst the stands? • The superb quality of the natural warmth, colour and detail of the new Imagine graphics on the Micro Nav airfield simulator. • The “eavesdropping” speech recognition system designed to drive Frequentis’ integrated tower tools and EFPS system. • ADS B displays of London terminal and enroute traffic by both Qinetic and FRA. • An intriguing system called “The Intelligent Airport” an integrated approach to providing an Advanced Surface Movement Guidance and Control Systems by Transtech Airport Solutions.

Most Welcome Development? For me it was the sheer numbers of companies now offering Human Factor and Ergonomic design services and consultancy to the ATS industry. I mentioned the social side of the event. Well the most welcoming ATC stands acting as a focus for meeting and greeting were from the opposite sides of the ATM universe. The NATS stand was always very welcoming, as was the Mosaic stand promoting a public service view of European ATC. Controllers might find their view quite fascinating, so why not visit http://www.project-mosaic.eu/. Next year the conference moves to a new location, (the RAI Conference centre in Amsterdam), has a new name “ATC Global” and a later date - March 11th to 13th. With the number of cheap flights from UK airports to Amsterdam, and the fact that the RAI is served by a frequent direct train service from Schiphol it will never be easier or cheaper to attend the trade exhibition just for the day.

ence for the sessions. Registration and Entry to the Exhibition was however free.

The Conference

European ATM at a Cross Roads?

The Conference lasts for two days and this year was looking very much at the future of ATM. There was a truly international range of speakers and some useful question and answer sessions each day. The scope of the Conference, taken from their web site was • The key political challenges to developing trans-national ATM services. • The key technologies, ground-based and airborne, which will be required. • How appropriate safety management systems will be integrated. • Views of developing new ATM solutions from dynamic aviation growth areas such as the Far East. • How aircraft operators view the current plans – how they want to see the next generation of ATM service provision improved. • The implications for mitigating the impact of aviation on the environment for ATM service providers. • The evolving role of controllers. • The current state of ATM research. • The changing relationship between manufacturers and ANS service providers. • How airports will work to improve their aircraft throughput rates. • The impact of emerging new aircraft on the developing ATM infrastructure.

4 RAYTHEON

All is not rosy in the European Air Traffic Management garden at the moment. In the balance of European affairs there is a very definite trend of the States and Eurocontrol “fighting back” or at least being less subservient to a European Commission and Industry perspective. As a result the ATC Maastricht Conference reflected a degree of uncertainty, even frustration, about the Single European Sky Programme (SES) and about SESAR.

Single European Sky (SES) The recent critical Eurocontrol Performance Review of the SES programme has obviously worried quite a lot of organisations. The European Commission and commercial proponents of SES (especially the airlines) were strident and indeed almost frantic in their insistence that SES was going well and it was all the fault of nation states that current progress in many areas was slow. State and other representatives were quite robust in refuting this view and were unapologetic in their view that SES had to be for all airspace users, not just commercial airlines and commercial ANSPs. States had duties in terms of not compromising defence, security, environmental measures and effective regulation. On Functional Airspace Blocks there was obvious frustration amongst some states at the lack of progress so far. It was even suggested that if a bottom up approach to designing FABs was proving difficult then states should

consider intervening before the European Commission chose to impose FABs from the top. There was also a lot of frustration that so far SESAR output lacked detail and was rather un-ambitious. There was an expectation, (almost a demand), in some quarters that the forthcoming SESAR Operational Concept be much more detailed and ambitious. There was quite a lot of information on the new NextGeneration Air Transportation (NGATS) System project from US sources, but again the impression was that it was very much top down and lacked detail. There was also frustration expressed that the US/SESAR liaison was ineffective, more a political gesture than a real process.^

There was also a lot of frustration that so far SESAR output lacked detail and was rather un-ambitious.

The CEOs from Denmark, Sweden, Ireland explained that as they bought the same system (Thales Eurocat) they decided to co-operate on the customisation in order to save costs. In Denmark, for instance they say they saved between 30 and 50% of development costs because of this common standardization. They agreed to make updates every 18

months only. They said “We have to resist the urge to develop, or even build our own systems just on the argument that we have a complex and unique airspace or problems. Thales said: “We are not developing standards outside ICAO. It seems that ICAO wants to stay away in the future from setting standards, but wants to concentrate on applying those that already exists. The aim is to be compatible and inter-operable .The aim is to implement identical systems in the 3 countries by 2009.“^

4 CISM

CISM Forum 2007 in Langen, Germany Philippe Domogala, ^ by Editor

4 The PORTUGUESE Team with Isabel Cambraia. Photo: DP

Joerg Leonhardt, the CISM expert within the German DFS is organizing an annual a coordination meeting among all the major players dealing with CISM in Europe, called the CISM FORUM. There, players exchange their experiences and review their counseling techniques, in the light of those events. I was invited to participate in this Forum for a day, where many cases were discussed and analyzed. When one considers CISM one think it applies only to work related (i.e. Aviation) accidents or incidents. But requests for CISM can also be made following other traumatic events.

Suicide Germany CISM peers had to deal with such an event in the form of a suicide of a colleague. In a close environment such as a Control team in an ACC, this can have devastating effects. It was also a traumatic experience for the CISM peers involved with this event in February 2006 in Frankfurt ACC. The biggest question that came out of this experience is: how to inform other colleagues. Most of these colleagues felt both guilty (why have they not been able to foresee this?) and Anger (Why this?). Some of the CISM Peers themselves knew personally the person, and that added to the difficulty.

Lessons Learned The lessons learned from that experience were: In order to get rid of those guilt feelings, Psychiatrists will tell you that when someone has decided, or planned to commit suicide, there is almost nothing anyone can do verbally (i.e. with small talks ) to reverse his decision. Peers should try not to be alone when talking to staff, should prepare well beforehand, should deal only with the facts (not rumors), should not overdo it, should offer help, and should ask for full cooperation of management.

Providing CISM in Brazil The next major presentation was that done by Isabel Cambraia of Portugal, on her experiences with providing CISM to the Brazilian

controllers involved in the Collision last September (covered extensively in the last The Controller).This was a very emotional presentation that revealed many issues. Isabel had to forget everything she had learned and improvise from day one. She was so overwhelmed by the requests that she said she worked on “auto-pilot” for the whole duration of her visit, only sleeping 3 to 4 hours a night. (Brazil controllers involved were all military, and all in desperate need of help). The lessons learned from her experience: “It was unique, very challenging but emotionally very demanding“ she said. “a Team should provide CISM, not only one person and there is a need for a coordinator” To maintain confidentiality is important, and one has to be careful about the level of personal involvement. And she concluded by saying: “After such a CISM intervention, there is a need for your own debriefing and for a period of rebuilding yourself“ If one does not take care, one can become also a person in need of CISM!

Multicultural Differences

perceive that culture. As Aviation is already a multi cultural environment, it is essential for everyone to recognize the differences, especially when dealing with CISM. The forum was followed by a traditional dinner where everyone brings a specialty from its own region, and that also was definitively another good intracultural experience! ^

4 Human Factors

Incident Voluntary Reporting System – A success story at Maastricht UAC Raf Vigorita, ^ by Eurocontrol Guild (EGATS) Photo: RV

It was only a couple of years ago when our Controller Association EGATS with the effort and knowledge of Philippe (yes, the Editor, but back then a center supervisor at Maastricht UAC and EGATS valuable asset) started seriously thinking about reporting voluntarily and in total confidentiality incidents that did not qualify for mandatory reporting.

Non Punitive

4 INREP bulletin in the ops room.

The ever increasing traffic and complexity at the center, along with the experience of other associations, showed the need of this project to be developed and implemented in order to maintain a certain level of safety. It was about giving a voice to controllers in a direct and non-punitive way on every aspect of our profession, with special attention to safety related matters. We felt that listening actively to the end users of our system were the primary ways to prevent mishaps from happening rather than tackling problems after they had happened.

Implementation Difficulties The road towards implementation hasn’t been always as easy as we all hoped for, with few setbacks and delays along the way. Meetings were held with management, the center’s Safety Manager and Eurocontrol’s legal services to find a satisfactory common legal agreement on which we could base the foundations for this important project. A pivotal point was the protection of the identities of the reporting controllers. This proved to be a tough point to agree upon, as the legal systems of the 4 countries were are providing ATS for, had to be taken into consideration together with the special European status of the Eurocontrol agency. But in all fairness, even if all the parties involved in the discussions were after different goals, the commitment shown by everyone played a key role to unblock this complicated situation and agree on a common set of rules. When everything was set and done, other is-

sues came into play, not least an organizational and logistical problem. This process obviously took up some time, as it was not only a matter of finding a proper place for the Reports incoming box where controllers could drop their forms or where to find those forms and make sure there is always a proper availability, but also who was responsible for taking out the forms. For this we created a small group of 3 controllers Peers, known as trustees.

Finding Trustees They are the only ones to know the identity of the reporting persons. They then de-identify the reports (by removing the top part of the report containing the identity and returning that part to the controller, as proof of confidentiality and receipt). They then pass the de-identified report to an Occurrence manager who then distribute them to the right management person. An answer is expected within the following six weeks, a length of time necessary to give a comprehensive answer and eventually find solutions to a reported problem. Unfortunately not every problem has a clear and possible solution. Both management and the controllers welcomed the idea of having three EGATS board members acting as trustees, and a very professional and qualified colleague was identified and chosen as Occurrences Manager. The project is known in Maastricht UAC as INREP …

Convincing Staff Then the whole procedure had to be prepared and explained clearly to both management and controllers, in order to win everyone’s trust and make the result a success. For this, a series of briefings were set up, with all controllers and other personnel including management invited to attend. Although the very first briefings didn’t see a high level of attendance, word spread quickly within the operational staff and the following briefings saw a very active and interested attendance.

THE

CONTROLLER

4 Human Factors So, finally, in June 2006 the INREP project was up and running, with the blessing of all personnel who saw a valuable way to have an impact on safety in a more direct, personal way. It was felt (expecially within the controller community) that too often in the past their opinions and concerns were bypassed or simply put on hold. Now, they would be able to express their concerns on a series of issues and they would get an answer within a limited time frame.

Management Approval Furthermore, INREP enjoyed the approval from both management and operational personnel, which is more rare than a seeing a DC8, nowadays. Getting the input from our controllers or engineers, and having the commitment of management to follow up the important issues is gold. At much the same time, the TRM (team resource management) was introduced into Maastricht UAC, along with a brief introduction on INREP to their attendees and thus even more exposure to the project. For myself, being both an INREP trustee and a TRM facilitator, it’s been a great satisfaction to see the INREP project taking shape and enjoy a high level of professional input by our colleagues.

Importance of Feed Back But how to get back to our colleagues and reply and address their concerns? That is simply done with the INREP bulletin. Every three months, a new edition is prepared jointly by Philippe (still now, the project manager) and the Occurrence Manager. It contains all the reported issues, available solutions and answers, in order to address the controllers’ reported concerns and keep everyone informed. This is a rewarding, yet not

easy task. The difficult part consists in giving a comprehensive answer to a report by both not giving away the identity of the reporting person by remaining as general as possible with the wording, but at the same time trying to clearly explain what was reported in order for the answer to make sense to everyone. The last bulletin, especially, drew some criticisms from all parties precisely for not being as clear as all hoped. It’s obviously a learning process, and all the feedback is welcome to improve communications between parties. The last bulletin, has already addressed this problem and will surely be more satisfactory for everyone. But, nevertheless, the criticism shows that INREP is taken seriously by everyone, and how people are waiting for the problems to be addressed and answered.

Share experiences, [….] to prevent mishaps to happen rather than tackle problems after they had happen.

A Success All considered, and taking into account the high number of INREP forms received in nearly a year since implementation, (more than 80) this project continues to be a success. It was hard work to shape it and bring it to life, but now the important thing is to keep the momentum. The feed back bulletin is to be as clear and professional as possible in order to keep our colleagues interested and involved. Some reported issues have been already addressed and corrective measures taken, and the satisfaction amongst our personnel was rather clear.

People are waiting for the problems to be addressed and answered.

Issues now can be addressed and prevented rather than be fixed only after a serious problem has occurred. Most importantly, finally everyone involved feels responsible for safety in any form and shape, and this is the culture we always hoped for at our center. ^

Slater

Welcome to our popular Corporate Members feature Spotlight. In this issue I have chosen to revisit a dynamic company based in the south of England who are at the forefront of ATM simulation for training, design and evaluation tasks. Since we first turned the spotlight on them two years ago, they have won major international projects and have launched a suite of revolutionary visualisation tools. Because I feel the information Micro Nav has provided will be of great interest to you, our readers, I have decided to make this the first of a two-part feature on

About MICRO NAV: Micro Nav have a track record going back to 1988 of developing, delivering and supporting ATC simulators around the world. They are a specialist company with a reputation for innovation, customer support and understanding what users need. Their family of simulators is called BEST. The name stands for “Beginning to End for Simulation and Training” and it has proved that it delivers all of that. BEST covers all types of training including approach, area, radar, non-radar, tower, ground and military operations. It covers all levels of training from ab initio through rating and validation to conversion, refresher, TRUCE and ECT training. It is configured to meet different training applications from classroom, part task and skills trainers to full-scope, high-fidelity simulations of radar operations rooms and tower cabs. The power and scope of BEST allow it to be used for design, testing and evaluation work as well as training. New designs and procedures are tested and refined before being trained using the same system. This capability has been extended recently with

the addition of the visual tools and Micro Nav see extensive demands in the airport and ATC design market. BEST has one software base so that all the different implementations run fully together. Multiple airspaces, exercises and sectors can be run simultaneously and independently. All the runs are recorded and can be replayed and resumed into live working for debriefing and teaching. The BEST audio communications system simulates radio, intercom and telephone calls with a digital recording that can be replayed in synchronization with the exercises. Let’s catch up with their progress and their innovative product developments.

NATS Heathrow Airport, London, UK NATS ordered an advanced BEST 3D tower simulator in May 2005 costing some £1.5M. It was installed by the end of the year and entered service in January 2006. Micro Nav are the prime contractor and provide all the ATC simulation and training software. BARCO designed and supplied the visual display system. It has a 10m diameter cylindrical screen with ten Sim-6 Ultra projectors. Their digital control facility gives full edge-matching and blending with colour and brightness balancing. Rockwell Collins supplied their EP-10 3D visual image generator. They also created the 3D visual models of Heathrow airport, the aircraft, vehicles and special effects. The simulator is used for training and for testing new concepts and equipment. It covers the changes scheduled for Heathrow including: the new tower; terminal 5; the facilities for the A380 and the new ATC equipment and procedures. Micro Nav have added stimulation interfac-

es and customised emulations to BEST so that the new systems being introduced at Heathrow are included in the training with high fidelity. These include: the electronic flight strip system; the lighting control panel; the ground movement display and approach monitoring system. Simulator ground traffic automation and pseudo-pilot facilities have also been enhanced to meet the operational needs of the new Heathrow airport. The simulation covers: day; night and dusk; reduced visibility; a wide range of weather conditions with rain, fog and snow; emergencies and unusual situations. The eye point can be jumped into different working locations as well as into aircraft and ground vehicles. Integrated area, approach, tower and ground operations can be trained and evaluated. Powerful data preparation tools allow NATS to cover different aircraft performance capabilities, traffic levels and operating conditions with full recording and replay capabilities. The new tower at Heathrow went operational in April. Meanwhile, the BEST tower simulator continues to work hard supporting the next phase of the airport development programme.

SPOTLIGHT Irish Aviation Authority, Ireland The IAA placed a major order with Micro Nav for BEST ATC simulators in 2005. A ten sector radar simulator and two 3D tower simulators were commissioned in August 2005. They are being used for a range of in house and third party commercial training. Micro Nav are emulating the Thales Cairde radar displays to give the IAA the operational look and feel that they need for their training. (see below).

^ Combined 2D-3D BEST Trainers sectors and boundaries so that exercises can be tuned and tests can be carried out. Typical exercises last up to 8 hours and include 2000 flights with peak loadings of 500 active aircraft and cover up to 16 sectors. The BEST Scripting Tool allows many sectors to operate automatically according to their co-ordination procedures so that controllers can run the key sectors without needing expensive support staff.

Skyguide, Switzerland Skyguide, the joint civil and military ATC authority of Switzerland, is a long term user of Micro Nav simulators. Their new training and operations centre at Dübendorf, near Zurich uses BEST extensively for their training. They will have two 360-degree tower simulators, six combined 3D-2D tower simulators and large radar simulators all driven by BEST. Further 3D-2D simulators are housed in two vehicles delivering mobile simulation across Switzerland. BEST is also being widely used by Skyguide as a stimulator in their training and development systems for their operational radar workstations. Micro Nav have developed interfaces so that BEST stimulates the Skyguide systems with radar data, flight information, AFTN and OLDI messages that match the operational standards and formats.

NATS London Area Control Centre, UK NATS use BEST to support their training for the LACC at Swanwick in Hampshire. Micro Nav delivered special software to speed-up the creation and testing of large exercises for the conversion training of controllers at the centre. Real traffic samples can be imported and edited as needed. The BEST Sector Loading Information Monitor displays and records traffic data at selected

ASTAC International, UK and elsewhere ASTAC use BEST radar and tower simulators in their aviation colleges at Gloucestershire Airport and Shoreham Airport in the UK, and overseas in Almaty, Kazakhstan and Tbilisi, Georgia. ASTAC provides a wide range of aviation training courses that have been approved by ICAO and the Safety Regulation Group of the UK Civil Aviation Authority. They take advantage of the annual licensing options offered for BEST so that they can adjust their simulation costs to their fluctuating contract demands. Their simulators are used for tower, ground, radar, approach and area ATC training as well as self-teaching, data preparation and debriefing.

NAVIAIR, Denmark Naviair are using BEST to drive their training and development system as part of the DATMAS programme. BEST inputs a range of radar, flight plan and information data including Asterix, OLDI, AFTN and CPDLC. An “adjacent sector” workstation has also been developed to support OLDI transactions and associated controller training.

DCA, UAE Dubai BEST was selected by the Dubai DCA to provide both stand-alone and on-console simulation radar training. Interfaces have been developed so that BEST stimulates the Flight Refuelling RDS 1600 radar workstations to give full fidelity training. It was originally installed in 2003. This year it has

^ Artists impression of 360 degree 3D tower simulator been expanded adding further 2D Tower and radar capacity for low visibility procedures and other training.

Sharjah Airport, UAE The Air Traffic Control Unit at Sharjah Airport commissioned their BEST airport training simulator in 2006. Their package is tailored for airport use and gives an economic solution to local requirements for on-the-job support, validation and refresher training as well as emergency and contingency training. It covers 2D tower, ground, radar and non-radar operations and has data preparation and system management tools. Sharjah will be able to create their own and other airport databases with ATC environments and exercises. They will be able to trial new layouts and procedures. Initially they are focusing on supporting their tower controllers and on emergency and contingency training. This completes Part 1 of our Spotlight on Micro Nav.

Periods of Unrest

But Norwegian ATC has been in the news for some time, especially after the decision to close down some facilities and airports, but especially after the sudden announcement of the closure of Royken the main ACC in the country, south of Oslo. A few years back, the closure of Fornebu airport, close to Oslo in favor of Gardermoen, some 65 Km away caused some waves, it was followed by the closure of Trondheim ACC, in the middle of the country. This combined with an acute controller shortage and a few unfortunate management decisions by a newly appointed Director, who was a lady with a vision, but a vision that was not shared by the controllers, and confrontation followed. This led to a period of unrest that made the headlines. The controllers remained united behind their Association President, Rolf Skrede, who became a television and media star in the Country, as a result. One has to realize that Air transport in Norway is essential. The country is very large (over 2000Km long) with mountainous areas, cut by fjords, making ground transportation difficult and lengthy. Also the country location at the far North of Europe means that business connections and holiday travel is mostly done by plane. Therefore any serious ATC disruption is particularly felt by everyone inside the country. Finally the old management resigned and a new director was appointed, who immediately restored peace (as well as a substantial increase of salaries for controllers) and today the working relations are once again harmonious. Smiles are back on faces of staff going to work.

glass elevator running on the side. (not good if you are afraid of height) It is equipped with latest technology, bright displays, no strips, no paper. The working positions are variable in height, so that controllers can choose to work sitting or standing up, and adjust the height of the table according their preferences and own height. The large displays can also electrically be tilted to avoid sun glare . It is a pleasant atmosphere and controllers working there are happy. Working with electronic displays (and strips) poses no problems to the controllers I spoke to, and the ergonomics looks very good as well. Traffic in Norway is booming thanks to a strong economy driven by oil, and when we know the price of petrol today, we understand why.

Safety Issues The new Management and the controllers have decided to concentrate their efforts in the future on safety related issues, especially when introducing changes. Basically how changes affect safety, how to discover latent failures (those which are buried inside the system for years waiting to pop up one day) and how to interpret incidents and act upon them. A long term study has been initiated, and everyone is interested in the results. Eric Lofquist, a former US navy pilot, married to a Norwegian controller, is currently preparing a PhD on this subject and explains part of his work as “the art of measuring nothing“ meaning how to measure safety in an already ultra safe environment, and how to draw meaningful conclusions when you have an accident is the challenge in safety monitoring.^

Norway is one of the Scandinavian Countries that normally sit quiet and maintain a low profile. If was not such a thing some 1000 years ago, as Vikings ruled, and, as some said: “discovered America, but did not tell anybody about it…“ Norwegian Controllers have always been good support for IFATCA, and their association was one of the 12 founding members of IFATCA, back in 1961.

Back to the Future ^

by Ayman Mahmoud (Egypt)

It was afternoon when I back home after long day of hard work, I was taking my lunch while watching TV it was the film “Back to the Future”, I like this film although I have seen it several times.

The Dream I fell asleep and had a very strange dream, I was inside the events of the film, yes, inside the film of back to the future, I met Marty driving his time machine. I introduce myself and asked him to enter date of 2050 into the keypad to see the air traffic control in the future, and after few seconds I found my self in the year 2050. I went to my ACC, I was surprised, there were a lot of screens, a lot of traffic in each one but very few controllers, “what is going on?“ I asked my self and went to see the radar screen, I saw the map of many FIRs, yes it was the map of Africa FIR, It was a map of entire continent so I decided to check what is going on. I went to the library, I didn’t find anybody but I heard an electronic voice: “can I help you” I said “yes”, “I want to read the current ATC manual, the electronic voice said “please take a seat” I take a seat and suddenly a screen appears on front of me, then a map of the world appeared in the screen with only six (6) ACCs, yes only one (1) ACC for each continent.

The Airspace The airways are straight lines from any aerodrome to another one inside the continent, no restricted, prohibited or dangerous areas, few conflicts points and all the flights seem to be above flight level 450, and with just 200 feet vertical separation. Then I saw the map below flight level 450, totally different and another type of separation, it was separation between flying cars from the ground till flight level 300 with vertical separation of 1000 feet because it was a new technology and it will be 500 feet in 2055. The gap between flight level 300 and flight level 450 was reserved to military flights. Suddenly I remembered some thing, there

was no voices at the ACC when I was there so I decided to back again to the ACC.

The ACC When I went to ACC I saw every one working through keyboard, yes it was data link communications between aircraft and flying cars and air traffic controllers, but there was some thing strange, how could this few number of controllers manage this huge quantity of traffic, so I went to the supervisor screen to see it. I found a big surprised waiting for me, I discovered that a lot of controllers were working at home, yes believe it or not they are separating at home through data link communications by their personal computers and the few numbers of controllers in ACC was only to coordinate between the controllers at their home and for emergency cases.

guage is not English language fired most of the controllers who didn’t pass level 4. Now the controllers of this federation are working in private companies which offer separation services for a cheap price but below flight level 100.

IFATCA in 2050 But, what about IFATCA in 2050, so I decided to go back to the library again, I told the electronic voice that I wanted to read some thing about IFATCA “ I take a seat again and on the screen I saw the web site of IFATCA. The home page was the same as 2007 “IFATCA has been representing Air Traffic Controllers for more than 83 years, and has more than 50,000 members in over 200 countries”. I asked my self how could the number of the controllers be the same as 2007, it is supposed to be more than that number with this density of traffic of flights and flying cars, and I discovered the bad news: it was the existence of a new federation, it called “IFFATCA” International Federation of Fired Air Traffic Controllers Association, it was established in 2010 after applying level 4 of English language in March 2008. The civil aviation authorities in the countries whose native lan-

When I read about the new federation IFFATCA I decided to return to the Future, so I left the library and asked Marty to enter date of 2007 into the keypad. When I came back I heard a human voice say “wake up dad it’s 8 o’clock “it was my little child Rahma waking me up. It was just dream. ^

Now the controllers of this federation are working in private companies which offer separation services for a cheap price but below flight level 100. THE

Africa/Middle East Meeting in Johannesburg South Africa ^ by Haske Jibrin The 17th IFATCA AFM Regional Meeting was held in Johannesburg last November. It was one of the best organized regional meetings witnessed in recent years and this should not be surprising considering the economic and technological standing of hosts, South Africa. The theme, “The Challenge of Air Traffic Management Provision”, provided the participants with an excellent forum for the acquisition and exchange of professional and technical knowledge while keeping participants abreast of the latest thinking and developments in our esteemed and prestigious profession. It was also an opportunity for old friends and professional colleagues passionately concerned with the development of the Air Traffic control profession to once again come together to discuss their passion ,review the progress or lack of it, since the last meeting.

The urgent need for African countries to make the financial investments required to bring up to international standards the 500 national airports and 117 international airports.

Attendance The meeting was graced by eminent personalities, top government officials , the military, pilots, air navigation equipment manufactures, training institutions, university dons, researchers as well as delegates from 25 IFATCA member associations. Zimbabwe and Morocco were also in attendance as observers. Equally impressive was the presence and robust participation of reputable corporate organisations mainly concerned with the growth and development of the aviation industry in the region as well as globally. Some of these organisations were involved in the Meeting as sponsors or exhibitors while others yet participated fully in the deliberations that took place during the meeting. Some of these organisations included ICAO, IATA, CANSO, SWEDAVIA, ATNS, South Africa Weather Service and ASECNA. Others were Flight Craft Aviation, Thales, SAAB Grintek, Denel Aviation, SACAA and AlPA-SA.

Opening Ceremony The meeting was declared open by the Honourable Minster of Transport, South Africa, Mr Jeff Radebe signifying the importance the South African Government attached to the meeting. In his opening comments, Mr Radebe identified with IFTACA position on the application of Human factors Knowledge being of high priority. He stressed that the goal of the

Government was to minimize the risks associated with aircraft navigation through internationally recognized training and adherence to international standards in the operations of air traffic navigation systems. He equally said that that South Africa has embraced the proposition of IFATCA that sufficient resources should be committed to the establishment of robust and independent safety regulations at national, regional and global levels in order to cover human and equipment management in air traffic navigation. He also expressed the urgent need for African countries to make the financial investments required to bring up to international standards the 500 national airports and 117 international airports as a measure of reducing the relatively high air traffic accidents in the region. The Honourable Minister also old the meeting that the South African Government has approved a five-year strategy for the regulation of air transport in support of the Accelerated Shared Growth Initiative of South Africa (ASGISA) which is expected to enhance the prospects of South Africa as a favourable air travel destination. In his welcome address earlier, the President of Guild of Air Traffic Controllers of South of Africa (GATCSA), Mr. Peter Van Rooyen said that his association has grown from a trade union to a professional group through a close collaboration with ATNS under the exemplary leadership of the Chief Executive Mrs. Wrenelle Strander. He applauded the Flight Safety Foundation (FSF), the Civil Air Navigation Services Organisation (CANSO), the Royal Aeronautical Society in England (RAeS) and the Academie Nationale de L’Air et de L’Espace (ANAE) for their unprecedented joint resolution decrying the increasing tendency of law enforcement and judicial authorities to attempt to criminalize aviation accidents, to the detriment of aviation safety. He expressed the hope that the meeting would inform and educate all participants to their overall benefit and enrichment. Also making his last opening address at an AFM regional meeting, the EVP Africa/Middle East, Mr Albert Taylor, reiterated the main objectives of IFATCA as including; the promotion of safety, efficiency and regularity in international air navigation, offering advice in the de-

velopment of a safe and orderly system of air traffic control and upholding a high standard of knowledge and professional efficiency among air traffic controllers. In achieving this, IFATCA cooperates closely with national and international authorities and institutions concerned with air navigation. Mr. Taylor also said that the region offers vast and untapped business opportunities for visionary leaders who could see that the region ,with the saturation in the Western trading block, represented the next phase of explosive economic growth after Asia.

Co-Operation The meeting therefore was aimed at sensitizing all the stakeholders in the region to the challenge and to stimulate cooperation in the development of strategies and the sourcing of the resources required for the enthronement of aviation safety upon which the expected economic growth and development will be based. He told the meeting that a cream of aviation experts and reputable organisations were at hand to provide participants with latest ideas in their areas of expertise and therefore urged delegates to fully take advantage of the occasion for their professional development by not being passive observers but rather active contributors. He commended the excellent relationship existing between ATNS and GATCSA while urging similar arrangements in other countries of the region. He also commended the management of ATNS for providing a full scholarship for one of the Ugandan controller who was recently pardoned by the Government of Uganda following the intervention of IFATCA. The President and Chief Executive of IFATCA, Mr. Marc Baumgartner who joined the opening ceremony shortly after arrival expressed pleasure for the impressive gathering at the Meeting. He commended GATCSA for accepting the challenge of hosting the meeting and expressed the hope and confidence that it would be worth the while. The guests and delegates at the opening ceremony were thrilled with the impressive performances of the cultural troupe at the occasion .Participants were exposed to the rich cultural heritage of the people of South Africa.

(IFALPA). Others were Koumassou Coulibaly (ASECNA), Patrik Peters (IFATCA EVP Europe), Dr. Glen McDougall, Peter Marais, Colonel E.Zimmer and Dave Gleaves. Some of the topics that were addressed at the meeting by these experts were as follows: • State Sovereignty/Airspace Re-organisation • Military Coordination • ATC Commercialization Policy: Has it Been Effective? • Human Resources • Safety and regulation • Risk and Hazard and Analysis • Incident Reporting Systems • Business Cases for Africa – ATNS, IATA, CANSO

Resolutions At the end of the robust and incisive discussions at the meeting a number of resolutions were made with a view to improving some of the situations that were found to be of concern to the delegates as they militated against the positive development of ATM in the region. The meeting encouraged national aviation authorities in the region to embrace regional integration of ATM systems. The meeting, while upholding the endeavors of CANSO member nations in the commercialization of air navigation services, cautioned that the process should ensure viability of the concerned organisations through a clear economic and legal regime and that a transition period for the commercialization processes be instituted.

Tribute to Albert Taylor By all parameters the 17th IFATCA Africa/Middle East regional meeting was a resounding success and was quite historic. The efficiency and promptness with which activities were marshaled were indeed commendable. Furthermore, The EVP AFM, Mr.Albert Taylor expressed his decision to retire from active IFATCA service having served for nearly two decades in several capacities. In his closing remarks at an emotional closing ceremony, he thanked IFATCA Board, GCAA, ATNS, Regional Support Group and Member Associa-

Presentations

FATCOA A brand new professional association for French air traffic controllers We are really happy to be back.

irst of all, the association has been created about two years ago, by Patrick Gristi (its secretary and ILO), Jérôme Louchet (our financial tyrant) and myself, Cédric Robin, current president of the FATCOA.

PCA, formerly representing French controllers in IFATCA, has done a very good work during all these years of activity for IFATCA. APCA was at the very beginning of IFATCA and its contribution to the ATC world is tremendous. Famous characters like J-P Lesueur are still vivid in the memories as the pillars of IFATCA.

he 1998 annual conference held in Toulouse was somehow the beginning of the end. The association was torn apart by the clan of those who had the power and those working effectively for the association, namely Patrick, Jerome and myself. As it was more and more obvious that both clans were heading towards opposite directions, I decided along with Patrick and Jerome to create a new association, able to challenge APCA not only vis-à-vis the French Civil Aviation Authority but also IFATCA.

onsequently, our executive board has taken the strong requirement of a total transparency of its actions. We have based the organization of the FATCOA on the very same architecture of IFATCA, thus enabling a rapid and efficient way to put in place operational cells or commissions to stick to important topics.

ur association is growing fast. The executive committee is now made of a solid and efficient team actively working into the technical, professional and legal commissions. We are seeking representatives from

French overseas territories to get involved into the four regions of IFATCA, not in the prospect to be more powerful but with the willingness to provide our members with more information that could be useful to improve their working conditions on the technical, professional and legal levels. This could be as well a good opportunity to share their experiences with other people (neighbors sometimes) from the same area.

ctions for the future involvement are quite simple: • To improve our membership • To increase our influence upon the French CAA • To help as much as possible weakest countries to voice out their problems and concerns • To stick to IFATCA actuality and be more involved in the increasing challenges IFATCA will have to face in the coming years We are really happy to be back. We look forward to working with all of you. FATCOA Team ^

Controller Consultation in New System Integration Peter Leung ^ by (Hong Kong) Technological advancement during the turn of the century has improved by leaps and bounds and modern ATC equipment has been developed to a stage with many functionalities and is able to achieve multiple tasks of high complexity.

Information Overflow A great deal of information can now be displayed to the controller. Is all this information useful? Is it assisting the controllers or causing false alarms? Is there too much information presented to the controllers? Professor Sidney Dekker, in his article â&#x20AC;&#x153;Human Factor: Conflict Detection and Human-machine Coordinationâ&#x20AC;?, has pointed out in the conflict detection scenario about what should have been the correct information possibly turning out to be something that may cause mis-interpretation, ending up with a wrong conclusion and the associated human factor issues relating to conflict detection. Therefore, to design a good ATC system, apart from the hardware reliability, one of the most important elements that should be considered is the selection of those functionalities available suitable to the controllers and their operational environment. Who are the best people to do this? Nobody other than the controllers themselves.

a user-friendly system. It is not unusual to see that service providers on occasions may have to adjust the procedures a bit to suit the system. This is of course, not the right approach but in reality it happens often. A system should be there to assist the controller and not the other way round. The last time I was involved in a system installation was in 1997 with the ATC system at Hong Kong Chek Lap Kok Airport. Although the system is still running with high reliability, it lacks modern day functionalities and actions are in hand by the Civil Aviation Department to replace the existing system with a new one. I was fortunate enough to be part of this new project team as well and it is a good opportunity for me to make use of what I have learnt last time to contribute towards the replacement system.

Controllers Involvment With the replacement system, apart from ensuring that there will be good reliability from the engineering side, it is intended there will be wide spread consultation with the operational controllers relating HMI issues, functionalities and ergonomics of ATCC design, etc. Apart from conducting consultation sessions during the various stages of the project stage, an ATC forum has been set up on the intranet to collect frontline inputs and suggestions from the operational controllers.

Good or Bad System? How do you consider a system to be a good system? A good system should be capable of providing the necessary support to the controller to perform their tasks under the operational environment. ATC systems with designs that do not involve the user will not be

Hong Kong still has a mixture of expatriate and local controllers in the operational force

and it is quite logical that in determining the HMI and ergonomics, we have to include cultural considerations as well in the design. It is with this in mind that the project team members have been selected, apart from the technical skill and experience level, with different cultural background. It is gratifying to see the response from controllers at this stage, especially from the younger generation, who have shown enthusiasm and eagerness to participate in their project. Initial work is at hand for the preparation of the new system concept design and the operational requirements. Visits to other renowned ATCCs and participation in the ATC Maastricht 2007 was arranged to keep us abreast of the latest technology. It is going to be a huge project and a great deal of effort has to be put in to guarantee success. With the consolidated effort from every division within the department and good directives and understanding from senior management, I am confident that we should be able to deliver the final product in 2012 to serve both the industry and the working controllers. ^

Landing the most complex Machine ever built … ^

by Philip Marien

Everyone has heard of the Space Shuttle: after it launches into space, it returns to earth landing seemingly as a normal aircraft to be re-used a couple of months later. But describing return to earth a normal flight is a bit too simple…

Selecting the Runway Before the actual return, the landing site needs to be chosen. NASA aims at getting the Shuttle back to the Kennedy Space Centre in Florida, as the preparation and launches take place there. The two alternates are Edwards AFB in California and White Sands AFB in New Mexico. NASA tries to avoid the alternates because shipping the Shuttle back to Florida (piggy backed on a modified B747) costs over 1 million dollars and adds days or weeks to the turn around time... The overriding factor in picking the landing site is the weather: less than 12-15 knots crosswind (depending on day/night/weight), less than 50% cloud cover 8000ft or higher and visibility should be more than 8 km. No thunderstorms or rain should be fore-

The Shuttle lands at 350 km/h, considerably faster than a commercial airliner.

cast within 30NM of the landing site, which can be tricky for Florida during certain seasons. NASA can change a landing site up to 90 minutes before the landing takes place.

The Runway The runway 15/33 at Kennedy Space Centre (KSC) is longer than the average runway, about 4,5 km and nearly twice as wide, 91 meters. The Shuttle doesn‘t need such a long runway, but with only one shot (a go-around is not an option as it has no propulsion when it lands), some extra space is needed just in case. In principle, the Shuttle will land at some 700 meters past the runway threshold. Several different navigation systems help the Orbiter and crew to find their way. First off there‘s a TACAN that provides guidance from about 145,000 ft altitude. As the Shuttle gets closer (about 18 to 20,000 ft), a Microwave Scanning Beam Landing System (MSBLS) updates the Shuttle‘s navigation systems. The Shuttle‘s crew also use a Precision Approach Path Indicator (PAPI) and a Ball-Bar Light System to fly the correct glidepath. In addition to the traditional runway edge and approach light system, the Shuttle Landing Facility has 16 xenon lights that produce 1 billion candlepower with an effective range of about 10 km. These are located at before the threshold and light up the whole runway when needed.

Birds Birds are of special concern at KSC because most of the Center is a national wildlife refuge that provides a home to more than 330 native and migratory species of birds. Special pyrotechnic and noise-making devices, as well as selective grass cutting, are used to discourage birds around the runway. The runway is checked for ‘foreign objects’ which could damage the landing Shuttle up to 15 minutes before landing.

The Procedure With the landing site chosen, the orbiter is rotated tail-first into the direction of travel. The two orbital manoeuvring system engines (in pods on both sides of the tail) are fired for 3 to 4 minutes depending on the path towards the landing site. This not only flips the shuttle to the correct angle for re-entry into the atmosphere, but also slows it down so gravity can start pulling it back towards the ground. This firing is called the de-orbit burn. This typically happens an hour before landing and on the opposite side of the planet to where the landing is foreseen.

Re-Entry into Athmosphere Roughly half an hour after the de-orbit burn, the orbiter will begin to encounter the effects of the atmosphere. Called Entry Interface, the Shuttle is some 122 km (400,000 ft) above the earths‘ surface, more than 8,000 kilometres from the landing site and travelling close to 26,000 km/h. Initially the orbiter is controlled by firing the aft steering jets to keep it in a 40 degree nose-up attitude. This angle is the best compromise to minimize heat build-up while also gradually slowing down the craft. As the atmosphere gets denser, the aero surfaces (wing flaps and rudder) gradually become more effective and the steering jets switch off automatically. Contrary to popular belief, since the late 1980’s, there is no longer a communication blackout (which was caused by a sheath of ionized air enveloping a spacecraft friction heated up the air around it) during the re-entry into the atmosphere.

At the end of Entry Interface, the Shuttle is still travelling some 13,300 km/h at some 885 Km from the landing site and 55 km (180,000 ft) high. Time to touchdown is only 12 minutes!

Approach Speed To slow down further, the orbiter performs a series of four steep banks, rolling over as much as 80 degrees to one side or the other. The series of banks gives the shuttle‘s track toward landing an appearance similar to an elongated letter „S.“ In the lower atmosphere the orbiter flies much like a conventional glider, except for a much higher descent rate, over 10,000 feet (3 km) per minute. At approximately Mach 3, two air data probes, located on the left and right sides of the Orbiters‘ forward lower fuselage, are deployed to sense air pressure related to vehicle‘s movement in the atmosphere. At about 45,000 ft altitude, the Shuttle will start manoeuvres to intercept the approach corridor. Although it can be flown manually, computers control the craft up to this point – a re-entry has only been flown manually once. Although the landing could be done automatically as well, the Shuttle commander assumes manual control, assisted by a Head Up Display, for the last 1,5 minutes of the flight, steering the ve-

hicle around the nearest of two (imaginary) Heading Alignment Cones on each side of the selected runway. With no go-around possible, it is of course vital that Shuttle pilots get extensive training before landing a multi-billion dollar machine. NASA has a fleet of Shuttle Training Aircraft (STA), which are highly modified Grumman American Aviation-built Gulfstream II executive jets. These simulate an orbiters‘ cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiters‘ atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. A Shuttle pilot needs at least 1,000 landings in the STA before getting his hands on the real thing.

Final Approach During the final approach, the vehicle drops toward the runway 20 times faster than a commercial airliner as its rate of descent and airspeed increase. Around 32 seconds before landing, at around 2000 ft, the pilot flares to a 1.5 degree glide slope, further reducing the speed. At the end of this manoeuvre, the landing gear is lowered: some 15 seconds before touchdown at about 100 ft, it is locked in position. The Shuttle lands at 350 km/h, considerably faster than a commercial airliner. Once the main gear is on the ground, a 12 m drag chute is deployed to help slow down the spaceship. The nose gear touches then touch-

It manages all landings and departures from the Shuttle Landing Facility, including air traffic within the Kennedy Space Center/Cape Canaveral restricted airspace. es the ground and the parachute is jettisoned as the Orbiter slows through 110 Km/h. After rolling to a gentle stop, some 20 to 30 vehicles will approach the spacecraft as it cools down and toxic/inflammable gasses dissipate. It’ll take about 45 minutes to 1 hour before the crew can disembark. Having watched a launch from a nearby beach some years ago, I have to say it is an experience that makes a huge impression. I can only imagine what I’d be like to watch a landing from the tower overlooking the runway…^

This is why bulldozers and helicopters – in that order – need two. Further, if helicopters are so safe, how come there are no vintage/ classic helicopter fly-ins? He also had something to say about following the rules:

Toilets with 800 PAX Recently tests were made to try the toilets of the new Airbus A380. Engineers had to think what can happen with 800 pax stuck in the aircraft for 15 hours and what they can throw in the toilets: so far they found items such as plastic cups, spoons, baby diapers, toothbrushes and even socks!

The rules are a good place to hide if you don‘t have a better idea and the talent to execute it. But if you deviate from a rule, it must be a flawless performance. (e.g., if you fly under a bridge, don‘t hit the bridge.)

Automatic Aircraft: The problem is that the A380 has over 1000 meters of toilet pipes and the flushing speed is in excess of 100Km/h and everything should be done to avoid toilet blockage. Well in the 1980’s I remember a Dan Air BAC one-eleven who flew very slowly. When asked why, the pilot replied that the had to keep the nose quite up, as the front toilets were unserviceable and the last remaining one, on the back, had overflow…

Helicopters and Rules I recently met an old bush pilot that hated helicopters. I asked him why and he said: To fly real planes you only use a single stick.

A 1960 old BAC one-eleven airliner was flown last October over England with no pilot in the cockpit in order to test a technology to control UAVs aircraft. The flight lasted 2 hours, and as the BAC 1-11 did not crash it was deemed a success. What I found interesting is that under the British civil aviation law, the pilot controlling the jetliner still had to be on board the aircraft. But he sat at the back of the plane using only a remote control to fly the aircraft. Interesting technology, which was mostly aimed at proving how a fighter pilot can eventually control an UAV at the same time as flying his own jet.

But then came the showstopper: When asking some questions we found out that an emergency crew sat in the cockpit of the BAC 1-11 just in case, and also performed the take-off and landing phases. Ah.. the full automatic airliner with passengers inside is not for tomorrow I guess!

Overheard on the Frequency in Germany: Runway ownership: Pilot: Lubeck TWR, DA ready to taxi, can I have Runway 27? ATC: No, it belongs to the airport, but you can taxi to holding point 27. Fokker 50 cabriolet: TWR: KLM1234 clear to land runway 24 Pilot: Ro…ger cle…ar hoo… and TWR: What is this high noise on the background? Pilot: It…is just normal cockpit noise. TWR: You sound like a Fokker 50 cabriolet… Pilot: Fine, it that case I‘ll close the window… Correct call sign… USAir 1234 do you read/? (after the 5th attempt): USair 1234, you are just like my wife, you never listen… USAir 234: Maybe if you called her by her right name she will!
