LIFE INSURANCE FOR HANG GLIDER PILOTS

Dear Editor, I am encouraging our members to think briefly about the dangers we face while flying and how one of those "can't happen to me" fatalities could change your family's life. Most of the pilots r meet love their families as much as they love flying, but many have taken little if any time to ensure that their loved ones have adequate resources to get along in their absence. How many months, without your support, would it be before your family would have to make uncomfortable choices? Could your wife work and raise the kids? Think about the ti.mes you have read in this magazine about taking up a collection for a family left behind! The analysis is simple: Consider how much income your family needs to live on and divide that by a reasonable interest rate to determine how much capital is required to provide the income. Income I Interest Rate = Capital Required. Life insurance is a very inexpensive way to provide that capital; $20,000 of income per year for your family for the rest of their lives requires about $250,000 working at 8%. You can obtain that $250,000 for about 2% of your yearly income at age 30 if you earn $20,000 per year (less than the cost of that new llight deck you were thinking about). Unfortunately most insurance companies want about three times the normal premium to insure your life while you fly, but there are a few companies who will work with us reasonably. Some brief thoughts on insurance: There are two types of insurance worth considering for most of us. Tenn insurance requires the least current outlay of money, but the cost rises rapidly with each year of age. Universal insurance combines a savings account with lower term rates to produce a more economical insurance over time. One company I represent has developed a universal insurance plan that does not ask if you are involved in any dangerous activities and offers the least costly insurance coverage for most ages. In addition it allows for safe, tax free, liquid savings at 8.6% and does not require a physical exam. !tis the best product I have yet seen for the hang gliding community. The USHGA office has a list of companies that do not rate hang glider pilots. Also review the article written by Doug Hildreth in the March, 1988 issue. It contains a lot of information on related subjects. Remember, life insurance is an inexpensive

Dear Editor, The following letter was read to the members of theSylmar Hang Gliding Association on Sept. 21, 1988: Anyone who ever met Jeff Scott would remember him with joy, love and respect. I probably remember him for as long as anyone present here today; maybe I saw him on his first three-minute flight off Sylmar, or perhaps the training hill. At first one was impressed with his great height-and as you knew him, with his great stature as a human being-his serious face which bloomed in th.e warmest smile. As the old bird watcher and the mother bird, Karl and I adored Jeff, and when he became ill our hearts were torn that one of our favorite "Birds" should be so stricken. But I shall speak of happier times which were the essence of knowing and remembering Jeff. When I was hugged byJeffmynosereached his sternum. I remember when he and Karl greeted one another, the kind smile on the face of the ymmg "eagle" and the adoring look on the face of the old "eagle" who realized his dreams of flight through his young friends-his "Birds" as he called them. I remember his sunburned nose and ready smile. I remember the "Baja Bug" which was truly dwarfed under Jeff and his oversized glider. I remember Jeff's first cross-country flight from the back side of Sylmar to the football field at Quartz Hill. Karl and I worried about him, fretting until Gary Valle called and said, "Jeff's home." This was at a time when XC was new; Karl envisioned Jeff frozen and I was sure he was starved. I remember Jeff on April 9, 1988 when I had the exquisite pleasure of riding with him in the Sylmar parade. We had great reminiscences of those wonderful past years of hang gliding in Sylmar; probably we were saying goodbye to a wonderful era-and probably I was saying goodbye to my dear young friend.

AIRMAIL I would like to read the Neptune Society poem which Karl's nephew read at Karl's memorial: Do not stand at my grave and weep, I am not there, I do not sleep. I am a thousand winds that blow, I am the diamond glints on snow. I am the sun on ripened grain, I am the gently autumn rain. When you awake in the morning hush, I am the swift uplifting rush, of quiet birds in circled flight. I am the stars that shine at night. Do not stand by my grave and weep. I am not there, I do not sleep. Soar safely on that big blue therrnal,Jeff. On Karl's marker the inscription reads,"Soaring with his friends." I choose to think you are soaring together. In memory of Jeff Scott September 18, 1988 Mary Dahlsten, a.k.a. The Mother Bird I would like to add that Karl and Mary Dahlsten have been long-standing supporters of the hang gliding community ever since it got started here in Southern California. A few years ago Karl passed away, but his surviving wife continues to rally to our side when it comes to dealing with hang gliding and political issues. Even though they never felt the sensations of foot-launched flight, they absorbed the joys experienced by the happy pilots landing back safely on the ground. Harry Martin Northridge, CA

WORLD TEAM SELECTION REBUTTAL

Dear Editor, The historical facts don't support the idea that the World Team Selection System has reduced participation ofranked pilots in the Owens Valley XC Oassic. (See Tom Kreyche's letter in the last issue.-Ed.) The fact of the matter is that the Oassic has had on! ya modest level of participation from top-ranked pilots for several years, and that that level was already declining well before the present system for ranking pilots for world team selection was implemented in 1986. The '82 Oassic drew 10 top-30 pilots, while the '82 So. Cal. League drew 13, the '82 Masters 11, and the '82 Nationals 14. The '83 Oassic drew 10, the League 11, the Masters 12, and the Nationals 12. In '84 participation in the Oassic declined to 8 , while the League drew 12, the

Nationals 17, and the Masters 11. In '85 the Oassic drew only 4 top-30 pilots, the Nationals 13, the Masters 9, and the League 13. Through 1985 the old points system awarded points largely on the basis of con test format, and prospective competitors in each of the years listed above knew that the Classic would be worth a significant number of points because of its high point value format and because the weather traditionally provided enough flights for maximum validity. The Oassic during these years was consistently worth a lot of points regardless of the modest and declining participation of ranked pilots. Yet despite the consistently high point values earned by the Oassic during this period, participation in the meet by top-ranked pilots declined significantly, and was always below the level of participation in other major meets. The Oassic wasn't held in 1986 and 1987, the first two years that points were computed under the provisions of the new World Team Selection System. In 1988 seven top-30 pilots competed in the Oassic, while 21 competed in the Nationals, 23 in the League, and the Masters was not held. The seven competitors in the '88 Oassic represented almost twice as many as competed in 1985, and more than the average of the number that competed in 'S4 and '85, under the old points system. The argument that the new system caused a decline in participation of topranked pilots in the Oassic cannot be supported; in fact such participation has slightly increased under the new system. What has changed is that the participation of top-ranked pilots in other meets has increased significantly during a long period in which it has declined in the Oassic, and that the new points system recognizes that the Oassic has no inherent value as a measure of pilot ability which is independent of the quality of the pilots who fly in the meet. The error is not in the presentsystem, but was in thepastsystem which gave out too many points based on meet format and did not look critically enough at the quality of the competing pilots. It is true that in 1988, because the Nationals was held in April instead of late August, and because the Masters was cancelled, and because '88 was the last (only) year of a world team selection cycle, that the Oassic this year occurred at the end of such a selection cycle instead of early in the cycle as it normally does. And it is possible that this influenced some pilots' decisions about whether to fly in the meet. However, other meets such as the Masters (Sept.) and the Nationals (often Aug. or Sept.) have operated with this disadvantage consistently and have been able to attract their share of topranked pilots.

The present World Team Selection System may not provide the best system for promoting competition, and it may not provide the ideal training program for the world team, but these are not the purposes of the WTSS, and they should not be. As a selection system the present WTSS is properly designed; there simply is no other way to measure a pilot's competitive ability except by measuring it against the abilities of other proven competitors. The Europeans realized this right away, and their original points system, the PIRS, incorporated from the very start a very heavy emphasis on the ranking of the competing pilots.

REMEMBERING GEORGE DIPERRIO

Dear Editor, Recently, my father-in-law George DiPerrio died in a tragic hang gliding accident at Mont St. Pierre in the province of Quebec, Canada. George was 62, had an advanced rating, and had been flying for over ten years. Despite all his experience and skill, he simply forgot to hook in again after completing his hang check and then being distracted. George loved his sport with a passion and was widely known in hang gliding circles as one of the nicest and friendliest guys around. It was not uncommon for him to spend many hours helping others with their launches, frequently at the expense of his own flights. In addition, George had donated much of his time clearing woods and building ramps in order to increase the number of new launch sites for the enjoyment of others. He especially enjoyed spending time assisting newcomers to the sport. "Smilin"' George, as he was often called by

HANG GLIDING

AIRMiIL his friends, took great pride in his ability to "keep up" with his much younger fellow pilots. He was one of the first in this area to be dropped with his glider from a balloon. His greatest thrill occurred last year when he launched off Mont Blanc, the highest peak in Europe. We will all miss hearing of George's hang gliding exploits, but we will certain! y never forget the wonderful memories we have of him. The family of George DiPerrio would like to thank all those fellow pilots who made hang gliding so enjoyable for him. Special thanks to Jim Lajoie, Bud Brown, Collette Carson, Phil Vangel, Nick Caci, Mary Kesslak, Ron White, the Skyriders of New England, and his friends at Morningside Recreation Area. He truly loved all of you. Anyone wishing to make a donation in his memory may do so by sending it to: George DiPerrio Memorial Scholarship, c/ o David Konrad, Treasurer, Chocksett Club, P.O.

MINI-BINER DANGER Dear Editor, In the September Accident Reports there was an incident discussed which makes me very angry, because it was unnecessary. A pilot was described having hooked aminicarabiner over a flying wire and lost control. Fortunately there was no injury. Back in March, 1976 a close friend of mine died as a result of this incident. His resulting loss of control caused a continued turn into a cliff face. A couple of years ago the USHGA began selling these "mini-biners" as a flying accessory. I wrote a letter which outlined the dangers of this exact problem. My letter never appeared in Hang Gliding nor did I get any response. I wrote again and finally heard back from Cindy Brickner. She advised that the USHGA was discontinuing sale of these mini-biners and all purchasers were being warned not to fly with these devices exposed. But my letter never appeared in print. My concern over an accident repeating itself was never conveyed. So, I try again. Get those things off your harness! Robert Caldwell Boulder, CO

I make every effort to publish all safety-related correspondence. I don't recall your letter so I may never NOVEMBER 1988

portrayed a biased perspective that doesn't tell the whole story. Elden is a great XC site. It is also endangered and difficult to fly.

PLA YA DEL REY CAMPAIGN UPDATE

John Johnson Phoenix, AZ

Dear Editor, I would like to thank all the pilots and friends who sent in cards to help save hang gliding at Dockweiler Beach. It is estimated that roughly 10% of the cards were sent in and they have definitely made an impact. The card program was funded by local area shops and pilots. There has been no expense to the USHGA or its members. I highly encourage those who have yet to send in cards to dig out their July issue and send in the pre-addressed cards. It is only by exercising our numbers that we can demonstrate a need to be included in city planning. Rick Perkins Playa de! Rey, CA

ARIZONA COMMENTS Dear Editor, I want to congratulate Geoff Lyons on his 195-mile flight from Flagstaff, AZ. I have a few comments on his short article that appeared in the Sept. issue. Elden is a very fragile site. The Flagstaff airport is less than enthusiastic about our presence and it is important that they be contacted before any flight. There is a maximum altitude restriction of 12,000 feet in the Flagstaff area. A number of local pilots are concerned that Elden will be closed in the next one or two years. Outside pilots (like myself) are responsible for most of the site-endangering violations. Please contact local pilots before flying Elden. Elden can be a very difficult and dangerous site. Launch is a steep slope in a narrow chute cut through pine trees. On the day Geoff flew, about seven of 15 pilots elected not to launch, and one pilot failed his launch. Crosswind launches are impossible. Turbulence at the mountain can be severe on a good XC day. Th ere are only a handful of pilots who have more than 30 Elden launches without a mishap. I take issue with Geoff's attitude in describing northern Arizona thermals. I was completely inverted twice in two "no-brain er" thermals on the same day as Geoff's flight. I don't doubt that high desert,flatland conditions are less demanding than the Owens Valley, but they certainly require brains. Geoff flew one of only four 150+ mile days we had this year, and I think his short article

P.S. An alternate way to experience northern Arizona XC is to fly Merriam Crater (20 miles northeast of Flagstaff). Many long flights have originated from this unique site. It features a launch in every direction, a 1,000-foot vertical and unlimited LZs.

ZEISET NOMINATION Dear Editor, I would like to public! y nominate Jim Zeise! of Salida, CO for the USHGA Presidential Citation. If any member has ever deserved hang gliding's highest recognition for their efforts on behalf of pilots in a national organization, I believe it is Jim. In effect, the rest of the country is learning what pilots around Region 4 and in the state of Colorado have known for years; when a job needs doing there is probably no one better qualified or motivated than Jim. In the past year, to the best of my recall, Jim has found time to be the Region 4 director, the world team coach, the acting executive director of the USHGA, and the person who has finally succeeded in securing legal radio communications on the FM band for hang glider pilots. Jim also found time to be an active instructor, examiner, observer, and competition pilot. However, one nagging question remains. With all of Jim's accomplishments over the last year, why is he unable to keep the Mountain Queen from vapor locking on that last pitch at Telluride? Robert Caldwell Boulder, CO

RESTORING THE MASTERS Dear Editor, To all those who are Masters of Hang Gliding enthusiasts, and who are interested in seeing it restored to its significant position in the sport in 1989, please write a letter telling why to: USAir Decision Makers, 1 Piedmont Plaza, Winston-Salem, NC 27156-1000.

under a total overcast and dampening the team's spirits with rain. The end of the third week saw two flights that moved Fly America another 30 miles. Spirits were low as the pilots watched the three weeks they were ahead of schedule diminish to nothing. But as of Oct. 4, halfway through the fourth week in Ohio, a 35-mile flight to Newark, Ohio and more promising post-frontal conditions have raised morale and kept the team right on schedule. The team has 362 east miles to fly in the remaining 28 days of October. An average of 13 miles a day will see the team arrive in Kitty Hawk, North Carolina by the deadline of November 1. Hopefully by the time you read this update Fly America will have completed its incredible journey. Those interested in following the team along the last miles to the Atlantic, or in finding out more about the touchdown celebration in Kitty Hawk can call: (213) 595-5195 or (805) 822-8852.

FLY AMERICA UPDATE

After the agonizingly slow pace of Nebraska, the Fly America team leaped into Iowa and literally flew across the state in 12 days. The last flight in Iowa saw Ian Huss fly over the Mississippi River and cover 107 miles, landing halfway across Illinois. The corn fields of Illinois slipped quickly beneath Fly America's wings and the team crossed into Indiana five days later. A 95mile flight by Ian from near Rensselaer to Marion, Indiana helped move the team across the Hoosier state in nine days. On Sept. 9 the team entered Ohio and for three weeks remained almost stationary in the northwest corner of the state. They flew only 30 miles the first week and 26 miles the second. In the Buckeye State hurricanes Florence and Gilbert spewed clouds northward, grounding the pilots

SEEDWINGS RELEASES "CG SLIDER PLATE" FOR SENSOR 510B & C MODELS Citing a need for a greater adjustment in trim speed with their kingpost suspension system Sensor 510s, Seedwings has developed a new kingpost base sliding plate, for new production 510s and as an easily-installed retrofit. The new CG slider plate is designed to accommodate the needs of pilots hooking in at the extreme ends of the glider weight range, and to help keep older gliders in trim, which traditionally "slow down" as the sail stretches over time. The CG slider plate is available from Seed wings dealers as a retrofit kit for $18. The new hardware was HGMA certified on Sept. 9, 1988.

as an inversion layer. Various lapse rates are shown in figure 1. If the air cools more than 5.5° F per 1,000 feet of altitude the air in this layer is termed unstable. Because of the natural pressure drop with altitude (less air presses down on you as you go higher) air expands as it rises. As it expands it cools at 5.5° F /1,000 feet. (There are fewer molecules whizzing around in a given volume and thus fewer collisions which are detected as heat.) Consequently, if the surrounding air is cooling the same or faster than this 5.5° F /1,000 feet, a parcel of air warmed at the ground will expand and cool but always remain warmer than the surrounding air. Warmer air is less dense than cooler air at the same pressure, so it will continue to rise. Meet the familiar thermal. In unstable conditions, air that has been given an initial upward impetus tends to keep rising at least until an inversion layer is reached. On the other hand, stable conditions suppress thermals and downdrafts because the surrounding air changes temperature less rapidly than the rising or falling parcel of air. Thus a heated or cooled parcel of air quickly reaches an equilibrium position and remains there. There are two more principles we must understand. First, any layer of air that is lifted becomes less stable. The reason for this is that the pressure drop with altitude is not linear. Hence, the top of the layer cools more quickly than the bottom of the layer as it rises. The lapse rate in the lifted layer becomes less vertical. Second, air tends to move from cool to warm areas. This is because the warm air expands, flows over the top of the cool air, and creates a relative high pressure area which results in the cool air flowing towards the relative low pressure warm air. This action results in the familiar sea breeze (daytime) and land breeze (nighttime). Near a slope gravity complicates matters, but theres ult is an upslope breeze during the heating of the day and a downslope flow in the cool of the night. Finally, we can point out two lesserknown causes of upward- moving air (most pilots are familiar with ridge lift and thermals). The first is convergence. As shown in figure 2, when two air masses come together they expand upward if they cannot escape elsewhere. ConverNOVEMBER 1988

gence is a common enough occurrence in our flying milieu. The second item is wave activity. Waves occur when a stable layer is lifted bya ridgethen rebounds down, up, down, up, and so forth in succession like a spring. As shown in figure 3, waves can exist many miles downwind from the mountain that created them. Research has shown that waves are

quite frequent in the atmosphere and often exist when a stable layer lies on top of an unstable layer reaching about to the height ofthe wave-producing mountain.

shadow even more and thus cooled faster.) When this occurs the valley begins to fill with a pool of cool, dense air that lifts the warm air present in the valley. As the warm air gets lifted it becomes less stable. It is perhaps already unstable or nearly unstable at some point above the surface, but the reduction of heating below it and the lack of movement produces little activity. However, as soon as it begins lifting it may autoconvect and send off large, light thermals. When it lifts into the air moving above it, it is pushed into the ridge and lifts even more. The lift produced by this large mass of warm air spilling out of the valley is smooth,continuousand widespread. We know it as a wonder wind. It is quite possible that a wave setting in on a mountain will simulate or enhance a wonder wind. In this case the warm layer in the valley will help activate the wave. However, if a stable layer exists close to the tops of the mountains, we shouldn't expect much thermal activity. This may explain why a wonder wind often sets in at the end of an otherwise blah day. With this background we can predict the occurrence of wonder winds. It is known that a clear sky towards evening is propitious. This is needed for the ground heat to radiate off and thus promote the onset of downslope breezes. Also, a westerly-facing slope meeting westerly winds is desirable. A fairly narrow or enclosed valley is a further desirable trait. Finally, a day exhibiting moderate winds and moderate thermals will most readily produce wonder winds. (Strong winds and thermals often mix and blow out the accumulating warm air.) All of these conditions are not mandatory for wonder winds to occur, but combine enough of them and you'll find your longing for lift fulfilled to repletion.

MAGIC AIR

the upper air dropping down to compensate, the upper winds are carried downward and ridge and thermal lift bedeck the mountains. As evening draws near, the lowering sun produces less heat with several results. First, ground-based thermals diminish in size, strength and frequency, normally stopping at some point. 14

This can result in a layer of relatively still air in the valleys since mixing is greatly reduced as shown in figure 4a. Next, downslope drift sets in most readily on the slope facing away from the wind as shown in 4b. (If this is an eastward-facing slope this downward flowing breeze is enhanced since it is in

To make things simple we'll state that magic air is converging air. There are several familiar sources of this magically converging air. One is near mountains that lie close to the sea. Sea breeze air is stable, so it tends to go around rather than over a mountain. As it comes together on the backside of the mountain it HANG GLIDING

converges and lifts. Any time such air is directed up a narrowing valley it may converge and create useable lift, not necessarily in the lee of a mountain. (Example: Mt. Saint Pierre in the Gaspe Peninsula.) Magic air also exists on top of a tall mountain that sends upslope breezes up both sides. This may be difficult to get into unless a thermal gets you above the mountain. (Example: Grandfather Mt. when it converges.) A lesser-known form of convergence occurs along the down wind side of large lakes. Wind moving over water flows faster in the lower levels due to less drag (it also changes directions up to 30° due to greater coriolis effect on the fastermoving air). When the fast-moving surface air meets the opposite shore it is slowed due to the greater drag of the land. The result is a convergence along the shore line as shown in figure 5. Often this is the place to look for magic air and thermals promoted by the convergence. (Example: the eastern shores of the Great Lakes.) The final source of magic air we'll mention is found in the middle of valleys on lighter wind days. In this case downslope breezes occur on all sides of the valleys, meeting in the middle and converging upward. If the heated air in the valley also convects, widespread glorious lift can occur as shown in figure 6. In this case it helps if the mountains are high and the valleys not too wide. (Example: Buffalo Mt. area in Australia.) Magic air is encountered perhaps less often than wonder winds, but every soaring pilot should be cognizant when it sneaks up so as to not miss a special treat.

MORE TO CONSIDER We've had some fun with evening magic, but there is an evil side to the sorcery that we should acknowledge. To begin, when cool air moves under the warm layer in the valley a shear layer (area of turbulence) usually develops at the interface of the warm and cool air. Also, in narrow valleys or high mountains a downhill wind can set in even though it is still soarable on top of the mountain (figure 7). (Example:Ellenville, NY.) In high desert areas the onset of the evening downslope breeze can be sudden and powerful, reversing the windNOVEMBER 1988

Unfortunately, the lower air is stable and moving very little. Thus, only the top of the mountain is deflecting air and it's as

though you were trying to soar a hill a hundred feet or so high. In the East it is often possible to note how far down the mountain the wind lines in the trees extend, and thereby get an idea about how much air is moving up and over the mountain and thus how much lift is produced. Hang gliders are ideal probes for examining micrometeorology. A number of concepts have been redefined to accommodate the scale on which we operate. These items include wind shadows, asymmetric thermals near a ridge, bolster eddies on a cliff launch and tip stalls near the ground. While hang glider pilots didn't discover wonder winds and magic air, they certainly explored and defined their limits much morethananyotheraviationgroup. With our dependence on lifting air and ourcomparativelylimited reach, we must strive to understand the atmosphere as best we can. Our reward is more and more magic air time and wonderful windage. • 15

CONCLUSIONS NAME: AGE: RATING: GLIDER: INJURIES:

Scott Beyer, passenger, Nick Adams 36 Advanced, Instructor Dream 240 Fatal

The following report was submitted by Pete Lehmann, USHGA Director from Pennsylvania. It has been condensed for publication from the original, very thorough manuscript (eight pages). He may be contacted at: Pete Lehmann, 5811 Elgin St., Pittsburgh, PA 15206 (412) 661-3474.-Ed. TANDEM TOWING FATALITIES IN XENIA,OHIO An Advanced and Advanced Instructor-rated Tandem I pilot was towing up tandem on a Delta Wing 240 Dream using an ATOL system. The passenger was Nick Adams, a reporter for the Springfield NewsSun and not a USHGA member. The passenger was hanging above and to the left of the pilot. The tow bridle was attached to the carabiner and then ran through the two hip loops of the pilot's pod harness. The passenger's spaghetti harness was not connected to the bridle. There was no observer aboard the truck. Conditions were very hot and humid and almost windless. The launch on a .8-mile run way behind an Isuzu Trooper was uneventful. There was an upwind leg followed by a 180° turn and a downwind leg, toanaltitudeofabout 700-800 feet. The glider initiated another 180° turn and the next report is that it had caught its left tip under the tow line. This caused a severe left turn and probably also stalled the glider. A "twang" was then reported and witnesses reported the glider to be in a descending, sharply-banked left turn. They agree that the tow line was still attached to the bridle (but not the tip) down to about 150 feet, but disagree as to whether it was released at the time of impact. The pilot and passenger were pronounced dead

The immediate cause of the accident seems to be the snagging of the tip by the tow line during a "step tow." This is not an unknown phenomenon, and indeed the possibility of its occurring is explicitly mentioned in Rob McKenzie's article in the June, 1987 issue of Hang Gliding. His description of how one can catch a tip perfectly fits the known facts of the accident. 1) There was a large amount of slack line present during the last turn. 2) He had been doing tight turns on his previous flight of the day and on the first turn of this flight. 3) The driver had been ordered by radio to accelerate the tow vehicle to tow speed. The driver has stated that on previous occasions the tow line pressure had reasserted itselfon the glider prior to the glider's having actually completed its turn. 4) A possible contributing factor to the snagging of the tip is the fact that Beyer was turning in the direction of his passenger. The presence of the passenger can limit a pilot's ability to clear turns, and in this case may have reduced the pilot's awareness of what was happening at his tip.

ACCIDENT REPORTS

There have been four reported this year. Eric Oppie's fatality is recorded above. George DePerrio's fatality would have made two, but for the fact that it occurred in Canada. This is an extremely frustrating type of incident for me. It has been written about in virtually every accident review article. Numerous other individuals have written articles approaching the problem from different viewpoints. It is not a matter of someone coming up with a new idea or a new approach to the problem, it is a matter of all of us on the hill-with every launch, whether our own or our flying buddy's-making sure this does not happen, To repeat most of the things we have said in the past: 1) Consider attaching your harness to the glider during setup and climbing into the harness, never detaching it from the glider. 2) Do your hook-in in exactly the same sequence every time. If you do your hookin before moving up to launch,always do it that way. If you carry your glider to launch, then hook in, always do it that way. 3) After you are hooked in, step through the control bar, look back over your shoulder, and make sure everything is straight and attached. 4) Hook in, do a hang check. Make it a club and site policy to do a hang check (or in very rare instances its equivalent) prior to every launch. 5) When standing on launch, lift the glider and feel the straps come tight. If you launch with loose straps then let the glider back down, but at some point prior to the run, lift the glider at least once. 6) Before beginning your run, and before yelling "clear," yell "hooked in!" 7) On every launch by every pilot, look specifically to see that he is hooked in (visually preflight the rest of his glider as well), and say out loud, "You're hooked in."

8) Lastly, and most importantly, if you unhook for any reason, you must repeat the entire process. The most consistent factor involved in a failure to hook in is the presence of something different. This can be a new site, or a NOVEMBER 1988

new glider. It can be a new harness. More commonly it is concern about, and the pilot's attention on, something other than launching. Conditions may be different. He may be worried about the launch, the wind, what happened to the pilot in front of him, or competition, juggling for position, what he is going to do after he is in the air, or fiddling with the radio or camera equipment. The other well-known factor is a flight being done for show. If you are demonstrating to someone-family or friends, news media, any sort of special observerthe chances of failing to hook in are significantly increased. Before stepping to launch you must blot everything else out of your mind. You must run through your mental preflight checklist, at the beginning of which, and at the end of which must be "hooked in!" as you stand poised on launch. For the next five seconds you can only think of five things:

Generation . ... RocketDeployed Hang Glider Parachutes.

1) Hooked in! 2) Wings level!

3) "Clear!" 4) Nose down! 5) Run hard! I am convinced that the only thing which will make any difference in the incidence of failure to hook in is a national , local and personal conviction. Every club, every group of flyers, every "buddy," and every individual pilot must make certain that he and every other pilot launching is hooked in. There is just no question about it guys, we must become fanatical about this!

with

steel. With as little as 2.5% by weight of lithium added to aluminum, it can reduce the weight by up to 10% depending on the application. The first experiments in Al-Li alloys were made in the 1920's when the low specific weight and higher specific strength were discovered, however the development of the Al-Cu-Mn alloys (Duraluminum) delayed further research in Al-Li alloys. Only in the SO's did Alcoa rediscover lithium as an alloying component, at which time they produced a 1.3% alloy. Difficulties were encountered during melting and casting bee a use of the strong reactivity of lithium. In addition, the Alcoa alloy exhibited poor toughness and remained the only Al-Li alloy used (by U.S. Navy reconnaissance aircraft). Be-· cause of this low toughness its produc .. tion was stopped in 1968. Due to the increasing fuel costs of the mid 70's, several companies started in.. tensive investigations into aluminum alloys with higher lithium content to improved uctility and fracture toughness. Since 1983 Akan International has of.. fered a new generation alloy with the designation OTO XXXA, developed by the Royal Aircraft Establishment in Great Britain. Alcoa and Cegedur Pechiney3A. 5 were next in 1984 with similar alloys and higher strength. The new materials are made from Al-Li-Cu-Mn-Zr and show good fatigue and sufficient toughness characteristics. The maximum lithium content by weight so far is 2.7%. It has been found that higher levels lead to "hot, short cracks" and embrittlement during extrusion casting. The recycling of Al-Li metal scrap is the greatest problem and has not been solved. Al-Li scrap should under no circumstances be mixed with Al scrap. It must be collected separately and sent to the manufacturer for remelting. Lithium contamination of less than .1 % in conventional aluminum alloys decreases the mechanical properties substantially! The strength of steel depends on the transformation reaction of the crystal lattice when it is cooled from a high temperature, whereas the improvement in the mechanical properties of aluminum alloys results from a precipitation reaction. During a tempering treatment, after the cooling-off sequence, finely distributed precipitation particles are created. These hard lithium particles

prevent plasticdeformationand increase yield strength. This precipitation treatment is accomplished at a temperature between 100° and 200° C. Strength and toughness can be increased by cold forming before the tempering procedure to over 72 ksi ultimate strength and 6%-8% yield. 6 Precipitation particles can be made visible by the transmission electron microscope (figure 1). Al3 Li particles and Al 2CuMg are shown in figure 2 enlarged 160,000 times. Tubes or other extruded shapes are produced by extruding a heated block of material through a die with a press (figure 3). To improve the strength and to meet dimensional requirements the extrusions are also cold drawn through dies. This process is needed to produce the high quality tubes necessary for hang gliders. The Swiss manufacturer Aluminium Menzikon, which pro-

7075-T73X corrosion resistant

duces aircraft-quality aluminum tubes for hang gliders, is already extruding AlLi alloys. European aircraft manufacturers are presently testing this material. Manufacturing In the manufacture of 7075 (Perunal) tube of 2" diameter with a wall thickness of .035", 18drawing operations are necessary with six intermediate annealings and surface quality inspections. At Aluminium Menzikon, Switzerland, these drawing operations would have to be developed for the new Al-Li alloys. Sufficient demand for the material from the hang glider and ultralight manufacturers is a requirement. The aluminum manufacturers have invested $30 million in the development of the alloys, including safety measures for the melting processes.

reduce the percentage of aluminum in the weight of aircraft from 80% to 25%. New generation materials will be developed even before the introduction of AlLi alloys. An increase in lithium content to 3% or 4% is aimed at through powder metallurgy, which will bring additional weight reductions. McDonnell Douglas and Allied Signal are actively pursuing this.

increase. The better materials will allow for the design of new aerodynamic features such as winglets, spoilers, etc. The sink rate of sailplanes has been dramatically improved through the use of fiber composites. Although the introduction of Al-Li alloys for hang gliders shows great promise it will not stop the strong advance of modern fiber composites for future high performance gliders.

THE BAD NEWS: It will be available in the

1990's. A further weight reduction of 25% is possible by adding beryllium, and the modulus of elasticity can be increased by adding silicon carbide fiber. 8 An addition of 20% by volume of SiC fibers doubles the modulus of elasticity of7075.

What will be the impact of the new materials on the design of hang gliders? With a yearly production of 150,000 tons of aluminum for western aircraft, some 100 tons of aluminum for gliders and ultralights is negligible. Hence the new Al-Li materials aim at a wider market, where we would be a very useful application. Fuel costs are not a consideration for us, but a weight reduction would certainly be greatly appreciated. The new Al-Li materials would reduce the weight of a hang glider by 4-11 pounds, or allow greater span resulting in a performance

FOREIGN INTRIGUE

''Testing, Testing . .. One, Two, Three'' by Dan Johnson

equipped with a telescopic post to lift the wing out of the "car wash" (vehicle-generated turbulence). Numerous computer measuring functions, including stress readings on the spars oft he wings, are recorded for later analysis. The computer gear also permits "interactive" readings that can be observed while testing is being performed. The wing is then tested until parts begin to show signs of failure on the stress readings. In this way any part about to fail can be changed or reinforced before continuing. As a general rule, VEST ALE is used for the rougher measurements, while E.S.P.A.C.E. remains valuable for more subtle measurements of glider characteristics. Stories reviewed from Wings! and Cross

Countrymagazines;edited for American readers. SPHINX LINKS

ESPACERACE Le French Hang Gliding Association has a testvehiclemuchlikethatused by American companies pursuing HGMA certification. The vehicle-named E.S.P.A.C.E.*, a French acronym for test vehicle-is comprised of a heavy mast built onto a Citroen automobile (a big, heavy car by European standards). E.S.P.A.C.E. has been in use since 1982, and in development for ten years, with what Cross Country magazine calls, "vast sums of money." The Citroen testbed is a kind of laboratory on wheels, and under the direction of Robert Caen, is now financially and technically operational. Several French governmental agencies helped in its funding, and refer to the finished product as "the most precise and sophisticated of its type in the world." Once Swiss, German and French wing certifications are standardized, E.S.P.A.C.E. will prove very useful indeed. The lone drawback is that the vehicle is based in Toulouse, said to be a ten-hour drive from the Northwestern France home of nearly every French hang glider manufacturer. • In case you're an interested Francophile, E.S.P .A .C.E. stands for Experimentation Sur Piste d' Aerodrome des Caracteristiques d'Engin. 46

Recently, another vehicle has arrived on the test scene. This one is acronymed VEST ALE (for Vehicule d'Essai de STructure d' Aeronefs LEgers). Quite a sense of name humor these French have, don't you agree? It was found that although E.S.P .A.CE. was adequate when researching the flying characteristics of a wing, it was not powerful enough to test its strength up to the

"To create VESTALE, a 360 horsepower Renault Turbo semi-trailer tractor was equipped with a telescopic post to lift the wing out of the 'car wash'." limits. To test a two-place hang glider or an ultralight wing to 6 Gs, you have to drive at 70 miles an hour. At these speeds, the wing will drag at approximately 900 pounds. Further, as wings can lift in excess of 2,000 pounds, the vehicle must be heavy enough not to be lose traction during the higher speed tests. To create VEST ALE, a 360-horsepower Renault Turbo semi-trailer tractor was

Claiming the title of the world's largest hang glider manufacturer, La Mouette of France also claims to have manufactured more of any one glider model than anyone else: the Atlas. Yes, even after being the choice of both the French and British teams in the American Cup of about 1981, the Atlas continues in production to this day. Estimates on the total number built hover around the 7,000 mark. By any measure this is a major achievement, ranking with the ubiquitous Cessna 150 trainer. Now, the Dijon-based company introduces a successor that isn't. It seems the Atlas will remain in production, but La Mouette offers their latest beginner /intermediate glider: the Sphinx. The Sphinx is a single-surfaced glider with an aspect ratio somewhat higher than the old Atlas, and with a floating crossbar. Germany's Drachenflieger magazine evaluated the new glider, and calls it a "good 'junior' glider." Still, it seems rather a tardy entry for the French giant, as the void of sweet-flying intermediate gliders has been targeted by most of the major manufacturers in the last couple of years. Those who question it future success, however, forget the huge network of La Mouette dealers all over the world. HANG GLIDING

FOREIGN INTRIGUE YOUNG, OLD, BLACK, AND LEFT-HANDED We all have been yearning for greater contest diversity (haven't we?), and now all can breathe a collective sigh of relief. A new annual event has crept onto the competition calendar, in the form of the Senior World Cup. Its age threshold has been lowered from 50 to 45 years of age. As hang glider pilots continue to age, this concept may develop, and no doubt the grayer-haired among us are already marveling that a "Senior Cup" is for pilots only a few years older than ourselves (you know who you are, don't you?). Since we have a Women's World Cup, this Senior Cup surely throws open the door to World Cups for Blacks, Jews and Left-Handed Pilots. Who can say where the hair-splitting will end? But, it's all good fun, and wonderful that our European counterparts seem determined to provide a Cup for All Persons.

If enough Senior Women show an interest, a separate female class is planned. Should you have an interest, drop me a self-addressed, stamped envelope and I'll send you the organizer's name.

DEPRESSED, BUT SEXUALLY FREE

A group of German psychologists investigated the probable depressiveness of people in an article published in Drachenflieger magazine. Looking at people in sensation-seeking sports, these esteemed doctors conclude that hang glider pilots tend toward a depressive nature. Further, they surmise that hang gliding holds the remedy and that all depressive patients should take up hang gliding. (Isn't that a fun thought?) The nicest thing about the article is a list, taken from the original psychologist's report, on the characteristics of German

hang glider pilots in relation to the average German citizen. The hang glider pilots scored high points for their business consciousness, for being sexually free, and for being depressive. They scored lower in being opportunistic, economical, tied to their family, and of being fearful. Thanks to the kind doctors, we can all live easily in our sexually free, businesslike, courageous, and independent depression. I know I'll sleep better now; how about you?
