INFLIGHT INFORMATION FREQUENTLY ASKED QUESTIONS

As you sit back in comfort en route to your destination, the Rex crew hope you enjoy this entertaining and informative light reading.

Q. Why do the flight attendants insist that all window blinds be up for take-off?

A. The most critical phases of a flight are the take-off and landing. In the most unlikely event of a situation that requires an emergency evacuation, it is important that crew and passengers are able to have a clear view of the outside conditions in case of obstructions. For example, before exits are opened, staff must check for fire or other obstacles that may present potential hazards during the evacuation.

Q. Why do I have to stow my hand luggage in the overhead lockers, under the seats or in the seat pockets for take-off and landing?

A. Flight crews are required by Civil Aviation Regulations to secure the cabin as well as possible for take-off and landing. As mentioned, these are the most critical phases of the flight, and securing as much hand luggage as possible ensures that, in the unlikely event of an emergency, the exits and aisles stay as clear as possible, in case evacuation is necessary. It is also important to keep hand luggage secure whenever possible to ensure heavier items do not become airborne within the cabin. This is especially important when the aircraft is experiencing turbulence.

Q. Why do I feel so tired from flying?

A. As the aircraft altitude increases, air pressure decreases. As the pressure decreases, the body absorbs less oxygen than it would at sea level – so, it must work harder to supply oxygen to the body’s cells. As the body is working harder, it becomes more tired.

Q. Why do I sometimes feel pain in my ears or sinuses during ascent or descent?

A. The sinuses and middle ear are air-containing cavities that connect with the nose via narrow channels. As aircrafts ascend and cabin pressure drops, air passes out of these cavities (without any effort from the passenger) to balance the cabin pressure. It is a different matter during descent, as the cabin pressure increases. The channels close down and must be actively opened by holding the nose and blowing to inflate the cavities. Facial and ear pain can occur during descent if re-inflation does not occur, and this is much more likely if the passenger has nasal congestion. If you must fly with hayfever, use a decongestant nasal spray before descent and buy some ‘ear planes’ to plug your ears.

Q. When can electronic equipment such as laptops, iPods and mobile phones be used?

A. All Personal Electronic Devices (PEDs) must be placed in flight mode if access to the tarmac (including by bus) is required during boarding or disembarkation, and when instructed to do so by the cabin crew. Small handheld PEDs weighing less than 1kg, such as mobile phones, can be used in flight mode during all stages of flight. PEDs over 1kg, such as laptop computers, must be stowed appropriately for taxi, take-off and landing, and are permitted to be used only during cruise when the ‘Fasten Seatbelt’ sign is switched off. PEDs cannot be used while crossing the tarmac.

Q. What is the average speed of the aircraft when cruising in flight?

A. Our Saab 340 has an average cruising speed of approximately 500 kilometres per hour. The Boeing 737-800 NG has an average speed of 830 kilometres per hour.

Q. Why do I have to get permission from the Captain to move to a vacant seat?

A. The aircraft’s take-off speed is calculated by the weight and balance of the aircraft, and many factors need to be considered for a successful take-off. Factors include the weight of passengers and where they are seated, the weight of cargo, freight and fuel, the distance available on the runway, etc. For example, if there are 100 or more kilograms of freight in the cargo, the balance of the aircraft will be better maintained if passengers are seated in the forward rows.

Air Turbulence

Q. Aircraft often experience air turbulence, but what causes it?

A. Imagine the air around the aircraft is water in a stream. We can see how water is disturbed around rocks or when two streams converge. Turbulence in the air is similar: as the aircraft passes through cold air or in the vicinity of terrain that has disturbed the airflow – often incorrectly referred to as ‘air pockets’ – the aircraft climbs and descends in the same way that a boat moves on water. Though turbulence can be uncomfortable, it poses no threat to the aircraft and is akin to driving on a rough or unsealed road. More severe turbulence can be associated with developing thunderstorms. Aircraft have a sophisticated weather radar that pilots use to avoid these areas. Occasionally, a flight attendant will discontinue serving passengers in turbulent conditions; this is a precaution to ensure everyone’s safety.

Q. Why should I keep my seatbelt fastened even when the ‘Fasten Seatbelt’ sign is switched off?

A. On occasion, the flight crew cannot foresee turbulence or it is not picked up on the flight-deck radar. Because of this, we could unexpectedly experience turbulence at any time. The company recommends that you always keep your seatbelt fastened while you are seated – for your safety, just in case unexpected turbulence is encountered.

Engine Noises

Q. Why do the aircraft’s engine noises change during the flight?

A. Aircraft need more power to climb than to descend, in the same way that a car needs more power to go up a hill than down one. Rex aircraft have more than enough power to climb, so shortly after take-off you will notice a change in noises as the power is reduced. The pilots also control the pitch angle of the propellers for various stages of the flight, and as they ‘change gears’ this can also be heard in the cabin.

Q. What should I do if I see or hear something that does not look or sound right?

A. Please advise your flight attendant. The flight attendant may be able to answer your query and allay any fears. If not, the flight attendant will contact the flight deck and advise the pilots of anything unusual. Rex encourages open communication and will always treat a passengers’ concerns with the utmost seriousness.

Welcome aboard, Captain Lachlan!

Our base in PER recently had a delightful visit from Lachlan. Lachlan is 15 years old and has been into aviation since the day he was born. When he wrote in to Rex to say that he’s a big fan, we knew we had to invite him to meet some of the team.

“It was an experience that I never thought would’ve happened, especially the kindness of the staff to go out of their way to make a little aviation enthusiast’s day,” said Lachlan.

“The staff allowing me to wear a pilot’s hat was a dream! Rex has done the best job. To go behind the scenes, to the meet the crew and the pilots was insane! I definitely recommend flying with Rex, as your day will only get better. From the Saab to the B737, Rex is the way to go!”

Thanks for your support Lachlan, it was great to meet you. See you in the skies soon!
