always had lots of time for any student who wanted to fly well. Many an advanced pilot learned much from Peter's willingness to share his experiences and techniques in advanced flying with anybody who wanted to listen. It seems if ever a dedication was in order, Jonathan Livingston Seagull should have been dedicated to Peter. The book finishes with, "His race to learn has just begun." Peter was a true friend, a humble and brilliant guy who lived for flying.

Wrongful Death

Your readers should know that the hang glider pilot has again been turned away by a jury. The wrongful death suit brought by Suzette Wills and her children for the death of Bob Wills on June 24, 1977, was in a Santa Ana courtroom for five weeks in October and November. The attorney for Suzette, a prominent trial attorney who rarely loses, proved that Bob was blown down by the filming helicopter's wake; in fact, this was even conceded by the defense during the trial. It was also proved that the helicopter pilot changed his flight path from the prior filming run and left rotorwash across the normal landing approach. Yet the jury, which included two powered-aircraft pilots, found the helicopter pilot innocent, by a 9 to 3 vote, after three days of deliberation, awarding nothing to the widow and kids. The verdict was a shock to the family members who attended the entire trial, Suzette and Maralys, as well as to Suzette's attorney. About all it proves is that the average juror feels that a hang glider pilot simply accepts the risk of crashing - even if someone else helps him do so. It's an unenlightened attitude but it's there. We know of no jury verdict for a hang glider pilot yet. The trial was long and expensive. As is so often the case, the jury saw the trees but missed the forest. Robert V. Wills Santa Ana, CA

Peter Brown Dear Editor, Peter Brown, a well-known Australian pilot died in a tragic motor bike accident on the 23rd of October. Peter was an absolute perfectionist in everything he did, and his flying reflected this well. He became one of the world's best pilots, as those who flew against him will long remember, yet Peter 4

On Tandem Flying

Dear Editor,

Holmbeck ...................................

I would like to commend Rob Kells and Steve Pearson on their exceptionally wellwritten article, "Tandem Flying," in the November '80 issue. They did a remarkable job of covering the subject without revealing their personal bias. I would love to see them write a follow-up letter reviewing their own personal preferences in equipment and technique. I have been flying tandem now for three years and have very definitely developed preferences. I am continually asked for advice, tips and instruction in tandem flying so there is a lot of interest within the sport. I also believe that a trial and error approach to tandem flying is asking for trouble where safety is so much more important. I agree with the principle, 'There should be only one pilot of the glider." My launch technique is slightly different, and I believe better. I have my passenger (who hangs on my right) place his right hand on my right forearm and his left hand on my back. Reasons: 1) Since I am the pilot, I launch the glider and my passenger can feel my moves in this position and more easily follow me off smoothly so we are a single unit of weight. 2) Should the passenger stumble, hesitate or react on launch, I feel this input on my forearm before it affects the glider and can more quickly make necessary control corrections. Even if he pulls my arm I can correct more quickly. I also find that it helps to place your feet the same (i.e. left foot forward) so that you both start your run with the same foot to avoid tripping. Choose your glider carefully; everything is worse tandem. Here is how I rate these gliders I've flown tandem: Glider

Practice What You Preach

valve the impact of the prone pilot against the frame. Many prone pilots do survive mid-air breakups by riding down in the sail with or without parachute, but it would seem preferable not to fall in at all. If the fact of supine safety could be admitted, it would be beneficial to all. Most pilots would be in the market for a new harness, an immediate boost to business, and then the death rate would drop precipitously which would be a further boost to business by eliminating the "death sport" image. The sky would be full of happy laid back pilots who wouldn't arrive in the landing area shivering with fatigue from the strenuous business of prone flying.

Dear Editor, TO: Messrs. Kells und Pearson: Practice What You Preach! It is my sorrowful duty to fault an excellent and informative article, 'Tandem Flying," in November Hang Gliding. You state, "You should make sure that your passenger is dressed appropriately. Long pants, sturdy shoes with good ankle support, and a helmet," etc. Yet, every single picture shows your good-looking passenger wearing shower-shoes, thongs, sandals or whatever, with no support and rather poor traction, I would wager. I have seen this tendency in California, and it appears to be catching on elsewhere: bare feet, in some cases, and an abundant number of low-cut tennis or jogging shoes. I feel sorry for the pilot who sees this and then emulates it, all the way to a broken ankle! Please advise strongly that pilots and passengers wear ankle-supportive shoes or boots. Steven D. Holte Snohomish, WA

Laid Back Dear Editor, I agree with Martin Bergman that broken ankles are preferable to a broken head. I know from personal experience that one can survive a 500-foot vertical dive into stony ground. We're both alive today because we fly safely - supine. If you fly head first, expect head injuries. Everyone I knew who died while hang gliding did it as a result of head or neck injuries while flying prone. If you fly above the bar, you will have a far greater probability of loss of control in a negative load situation and of damaging the kite through personal impact. I have heard no 1'ecent stories of mid-air failures that did not in6

Will The Real Dear Editor, I would like to correct an error in information that appears in the November '80 issue on page 38. The article on the Nationals in Ellenville was nicely written, however, the caption given to go along with the photos has me wondering. The name is OK - Bill Wiand - but the face isn't (pictured with Lars Isaacson). Bill Wiand was chief timer, not ombudsman, and the nice-looking chap with Lars in the picture is not Bill (nor is he the ombudsman). Oh well, one more guess to go. Granted, both men in question have beards and are handsome, but I know who the real Bill Wiand is!

Cover Correction Susan A. Wiand Pearl River, NY

Dear Editor, The November '80 issue of Hang Gliding was beautiful. Good articles and dynamite color. One minor complaint though - the pilot on the cover was not Sterling Stoll, but rather Bob Deffenbaugh, local hotshot pilot and one of the world's best instructors.

No Power Dear Editor, Due to recent incidents involving lowflying helicopters and other aircraft at Stinson Beach, CA (the hang glider landing area for Mt. Tamalpais State Park), the Marin County Hang Gliding Association, in concert with the Stinson Beach Village Association, would again like to emphasize that there is to be no motorized hang gliding at this site. Hang gliding at Mt. Tam depends to a large degree on maintaining a good relationship with the homeowners of Stinson Beach, who are very much upset by lowflying aircraft and aircraft noise of any type over the beach and town. We were recently in serious danger of losing this site because of a lack of consideration for the Stinson Beach dwellers. As this site is the major flying site for MCHGA and, we like to think, the most beautiful one, it would be a shame lo lose it. K.P. Davis Secretary-Treasurer Marin County HCA

NOW TWO SCHOOLS. EAST COAST AND WEST! Now. America's largest hang gliding school can teach you to fly on the west coast as well as the east coast.

Designed by Catto, one of the earliest pioneers in the modem revival of powered ultralight aircraft, the Goldwing uses conventional 3--axis controls in an un·· conventional configuration. Design fea·· tures include foam/fiberglass composite construction, a main and a canard wing, ailerons and spoilers, and winglets with split rudders. Because the Goldwing is capable of being foot-launched, no licenses are required for the plane or pilot. According to the manufacturer extensive stall and spin testing has shown the Goldwing is able to be flown with full aft stick without stalling, and it was proved to be very Glenn comments, ''The Goldwing is aimed at a market of ultralight: enthusiasts and pilots looking for a safe and affordable, state-of-the-art, fun flying machine that has the speed of an airplane and the versatility of a powered ultralight."

RANGER Striplin Aircraft Corporation, builder of the Foot Launched Air Cycle (F.L.A.C.) has been flying its new Lone Ranger since October 23, 1980. The first flight was at El Mirage Dry Lake, CA. A week later they flew it 12 miles to the Fox Field Fly-In near Lancaster, CA. Test pilot Don Vreivogel says that the Lone Ranger, with the tail and three--axis control, is easy to fly, stable and flies like a conventional aircraft. With the new tail design, the Lone Ranger can use any number of engine types in the tractor configuration. Designer Ken Striplin said, "We've done it, we have now totally reinvented the airplane." The Lone Ranger is built using the same fiberglass composite construction used in HANG GLIDING


the flying wing F.L.A.C. The enclosed fuselage has bomb-bay doors in the bottom so that it may be foot-launched, qualifying it as an ultralight. It has a tricycle landing gear with a steerable nose wheel and laminated fiberglass legs to absorb the shock from landings. The Lone Ranger has

by Doug Hildreth a 32-foot wing span with an area of 144 square feet. The empty weight is 185 pounds and gross weight is 435 pounds. The wings can be folded alongside the fuselage, providing a package 16 feet long by four feet wide by five feet high that can be trailered or towed. Striplin Aircraft (SAC) plans to market the Lone Ranger in two basic forms: the Quick Flight Kit which requires only assembly, and the Economy Kit that contains all materials to build the complete aircraft.

REGION I Alaska, Oregon, Washington

Region I. Over three-quarters of a million square miles of scenic beauty and fabulous flying. It extends from the glacier-covered peaks of Alaska to the glass-smooth lift of Dog Mountain, from the steady winds and forgiving sands of Cape Kiwanda to 6,000-foot thermals in eastern Oregon. Although no one has actually thermaled in either the exhaust from the Trojan nuclear power plant or Mount St. Helens, it wouldn't surprise me a bit if someone tried it next week. We have, indeed, been blessed with some spectacular geographical attributes conducive to the sport of hang gliding. Much of our real estate is governmentally owned, so that sites can be obtained. Private property owners have also been particularly cooperative. But, it is the pilots of the Pacific Northwest who make this such a special place. In addition to the Alaskan Sky Sailors, the Pacific Northwest Hang Gliding Association and the Oregon Hang Gliding Association, there are innumerable smaller clubs that have banded together to share the frustrations of site procurement, the sweat of site preparation and maintenance and the hassles of producing a meet or fly-in; but these groups also share the joys of camaraderie. The Alaskan Championship, the Klickitat, the Star Thistle, the Frostbite, the April Fools - are rapidly becoming ingrained traditions. As a director of the USHGA over the past two years, I am impressed that the organization really works. I am very impressed

with the quality of the directors, and I have seen them giving considerable personal effort and attaining significant good, not only for the organization but for individual flyers. the USHGA is becoming financially solvent; the computer has been a valuable addition and the powered rating system is complete. I see several problem areas where a potential for improvement exists. As with any volunteer organization, there is a lack of input to the Board of Directors, and frequently a delay in distributing information to the membership. There is still some lack of knowledge of what the USHGA can offer the grass roots pilot. With directors' newsletters and better magazine coverage, part of this will be solved. It still is important for each member to contribute his thoughts and opinions to the Board through his director. I have been impressed with how many times a point raised by a pilot or a small group has affected Board decisions. Lastly, although any time two or more free flyers and free thinkers come together, there is bound to be conflict and differenece of opinion, I am distressed by the unpleasant feelings that I see between clubs, cities, regions and coasts. The ultimate goal of each of us is to enjoy the freedom of flight at home and as we travel about the country. I am convinced that the USHGA has, and will continue to significantly affect our ability to attain that goal.

solitude and the fulfillment of a dream. Bird's Eye View Tolife,Dan Gravage of Livingston, Montana, it

WHAT COULD BE MORE INCREDIBLE? by Lauran Emerson This is the last Bird's Eye View. As a firm believer in the theory that all institutions, with the possible exception of Dennis Pagen, should be dissolved every couple of years, Lauran is dissolving the column. Ed. A winter storm is sweeping the landscape. The bleak outdoors bears a sinister resemblance to the long winter of 1978. That year, the first storm lasted five months and the flights of October had to carry us through till spring. That year, on a day like today, with Bonnie and Jose crawling over the typewriter and snowdrifts creeping up the side of the house, I first sat down to write about hang gliding. My intentions were twofold: to record a personal view of free flight, and to keep my mind from turning into mush during the snowbound months. Two years later, I'm not sure the writing served the latter purpose. I still find guinea pig food in the clothes dryer and popsicles in the breadbox. But I still try to laugh at the follies of flight and flyers, and record the human side of this awesome and beautiful thing we do. For several years, much of my time has been spent flying, associating and corresponding with other hang glider pilots. For several months, I've also had a chance to review comments about hang gliding from pilots everywhere: their answers to "What Does Hang Gliding Mean to You?" and other questions on their annual renewal forms. The comments reinforce my observation. Hang gliding, to hang glider pilots, means "Everything," "Almost Everything" and everything in between. It means freedom, 10

is "the biggest rush of all." To Ben Rogers of Alstead, New Hampshire, it is "an integration with the main engines of the universe." To John Harvey of Costa Mesa, California, it "offers the supreme individual challenge ... All in all, it satisfies fully." Again and again, flyers repeat the importance of aloneness in the sky, of a total awareness of themselves and their capabilities, and, after a flight, of the comraderie of their fellow pilots. Seldom heard are the macho sentiments seen so often in print. More often, humility and gratitude are the pilots' feelings towards this life in the sky that they share. Without their wings, hang glider pilots are a very diverse bunch of people. With them, they are bound together by a single activity which may be the most free and independent thing they've ever done. The simple and powerful joy of a perfect flight transcends ordinary associations. It is such a total and individual experience that those who share it are united by a very basic bond. For me, there was one day this summer when this bond was even more evident than usual. It was a day in August, when everything that usually goes wrong on a flying expedition went right instead. Six of us, longtime best friends, found a driver to lead us to a new launch site: a site we'd wanted to fly for many years. We didn't get lost. The wind wasn't crossing. No one forgot his equipment. Nothing went wrong. We launched and spent the afternoon flying thousands of feet above the ridges, river and ranches near Lincoln, Montana. By the time we landed, all that mattered was that flight. We were just six very happy human birds, standing around grinning and yakking and glowing in its aftermath. All that mattered was that flight, and that the six of us had been lucky enough to have been a part of it. The feeling is not unique to our small group. The glow of a good flight is always brightened by friends in the sky and on the ground. "Superb friendships with strong, gentle people," is how Dwight McKee of Camarillo, California, describes this comraderie which is an extra bonus of our wings. While flying may be the biggest thing in many pilots' lives, it is not the only thing. Most people who fly do so in their spare time. They are weekend pilots who must juggle jobs, homes, families and cash in order to fly at all. Flying is "my weekend therapy. It breaks up the work week and balances out my life," says Robert Heaton of North Hollywood, California. How fortunate we are to have such a balancer. As pilots, we are special. We are

not better than others, but we are luckier. We were born into an age that was a dream to every generation before us: to a thousand men over the centuries who looked to the skies and dreamed of silent flight. As for me, I have been even luckier than most. My vantage point as a mother and a flyer has brought a thousand bright moments, a hundred unexpected journeys, and many true friends for life. Our children were born into a world of mountain campfires, clear streams, thermaling days, and surrogate mothers and fathers that few children ever know, and they love it. Flying means so many things to me. Bob Perk of Waukesha, Wisconsin, strikes a chord when he says, "Hang gliding is the means by which I can get in touch with myself. It puts everything in perspective when I'm alone in the sky." And Missourian Roy Caton speaks for me, and many other pilots, when he says, "In five years, I still have not been able to find the words to express exactly what hang gliding means to me." Among those who managed to sum it up in a few words is California pilot Stanley Chase. "Using only my skills and judgment and whatever conditions exist," he writes, "I can soar with hawks. What could be more incredible?" I salute that sentiment. I hope that none of us, who are lucky enough to fly, will lose sight of just how incredible it is. As I take a break now, to let my fingernails grow back after 25 consecutive deadlines, I hope that others will keep that spirit of incredulity alive, in writing, by writing. Every bit of human folly or wisdom, every human perception of the awe and beauty of silent flight that finds its way into print will help preserve that spirit. And we will all become better, safer, wiser pilots for it. Goodbye for now. I hope to meet you in the sky some day. ~

HANG GLIDING



POWER PILOT by Glenn Brinks

EAA Ultralight Association

The EAA Ultralight Association has been the subject of a lot of speculation over the last year. At Oshkosh, the speculation ended when the official announcement was made that the group would be formed as a part of the EAA. Now, much of the initial organization has been done and the association is starting to take shape. Most importantly, the temporary officers have been appointed. They are: President, John Ballantyne; Vice Presidents, Bob Ring, Dennis Pagen and Lucky Campbell; Secretary /Treasurer, Marv Zellmer; Directors, Lyle Byrum, Tracy Knauss, Dave Starbuck and Don Stewart. Elections for these posts 12

will be held later, once the group has stabilized and is functioning smoothly. The first meeting was held on November 7 at the EAA headquarters in Franklin, Wisc. Among the results of the meeting were the appointment of committees, the adoption of a logo and the approval of a promotion program to attract members. The program will include advertisements, promotion in the EAA magazine, Sport Aviation, and in EAA chapter newsletters, direct mail distribution of the first newsletter, contact with pilots at fly-ins and a poster with application form which will be distributed. One of the immediate goals of the Ultralight Association is not just the signing of new members, but the formation of many local EAA ultralight chapters. To form a chapter, the requirements include ten current EAA members (if you have trouble finding enough EAA members, get a free copy of their chapter directory and call the chapters in your area), establishment of a time, place and date for meetings, election of officers and completion of an application form. (Available from EAA Chapter Offices, P.O. Box 229, Hales Corners, Wisc. 53130 (414) 425-4860.) Another major function of the Ultralight Association will be publishing a monthly newsletter. John Weaver (12530 Locust, Olathe, Kansas 66062 (913) 782-9334) is the editor and he will have the help of the EAA in getting the newsletter typeset and published. The first issue is being put together now and should be sent out before long. Liaison with the FAA and other government agencies is one job the EAA does superbly and the Ultralight Association is following in this tradition. At previous Ramona fly-ins, each ultralight was required to prove foot-launchability. This year, a few phone calls were made and the problem was resolved. At the fly-in, the FAA left the ultralights alone completely. In the future, this type of activity will become more important and also look for the Ultralight Association to establish a mutually beneficial relationship with USHGA, the Soaring Society of America and perhaps even with the Aircraft Owners and Pilots Association (AOP A) and other aviation-oriented groups. There's a price for all this, of course. Annual membership in the Ultralight Association is $25.00 and also includes EAA membership but not (in the interests of keeping costs down) Sport Aviation. For those who also want a subscription to Sport Aviation, the additional charge is $15.00. Those who are already EAA members can add a membership in the Ultralight Association for $15.00.

Illinois DOT Holds Ultralight Aircraft Seminar It seems that lately, most of our dealings with the government and various official agencies are antagonistic in nature - them vs. us., so it's nice to be able to report an agency doing something really constructive and helpful. The Illinois Department of Transportation, Division of Aeronautics, sponsored a seminar on ultralight aircraft. It was held November 14-15 at the Holiday Inn in Elgin, Illinois. About 250 people attended, and heard a variety of speakers. The EAA organized Friday evening's program and showed three movies; To Fly, John Chotia on Ultralights and a movie Bob Ring made of ultralights at the Lakeland fly-in. There was also a presentation on the EAA Ultralight Association, and a few new members were signed up. On Saturday, Bruce Coppernoll, Flight Safety Coordinator of the Division of Aeronautics, started the program with a talk on 'The Challenge of Growth of Ultralight Aircraft." Bill Adaska of Rotec followed with a discussion of ultralight design and structure. The final talk of the morning was on ultralight aerodynamics by Gene Utz, Chief of the Bureau of Aviation Safety of the Division of Aeronautics. After lunch, Nick Lung, Ultralight Judging Chairman at Oshkosh '80 talked about "The Care and Feeding of Ultralights" and Theo Moore of the FAA discussed low altitude weather. Finishing up the seminar was a forum and roundtable discussion. Perhaps this will be the start of a trend of government agencies dealing with ultralights in a responsible and constructive way. For more information on the seminar, call or write Charlie Wells, Illinois DOT, Division of Aeronautics, One Langhorne Bond Drive, Capital Airport, Springfield, Illinois 62706 (217) 753-4400 ext. 522.

American Ultralight Association The American Ultralight Association is being formed by John Chotia (manufacturer of the Weedhopper) to provide information gathering, communication and liaison with the FAA. The group is open to anyone interested in ultralights. An interesting aspect of the group is that there are no dues. Chotia wants the group to be funded by the various ultralight manufacturers as "an extension of customer service" and has already received some funding to get the group going. The AUA will have a quarterly newsletter and will also sell AUA t-shirts, hats and so forth to help support the group. So HANG GLIDING


far, Chotia claims a membership of 8,500. First priority for the AUA is to appoint a safety officer in each state to provide communication with the FAA and to encourage self-regulation through observance of the FARs. The safety officer's job will be to intercede if an individual is "unreasonably inhibited" by the FAA, but it is the AUA's position that if there is an obvious violation of the FARs (such as flying an ultralight into a terminal control area), the AUA will support the FAA. Chotia says he doesn't see the AUA as competition for the EAA Ultralight Association. "The EAA does its fly-ins and has a lot of club activity, but this is more of a political representation group." "When the EAA speaks, they have to

US HCA REPORTS

USHGA Report of the National Coordinating Committee by Les King Director, Region 9 This is an update on the status of possible federal regulation of our sport. The FAA continues to say that they are planning to issue a Notice of Proposed Rule Making. A couple months ago, the Federal Register scheduled this NPRM to be published in October. It now appears this will not happen until possibly next year. We don't seem to be too high on their list of priorities. My sources indicate that this NPRM will not make any distinction between footlaunch and power. I get the impression that the FAA would like to solve all their problems concerning hang gliders and ultralights with one set of regulations. I'm told the NPRM will take the form of a definition, probably based on weight. Below something like 150 pounds empty weight, JANUARY 1981

keep in mind the warbirds, the antiques, the experimentals and aerobatics and everything else they're involved in and I think it is important that somebody be there to speak strictly for powered ultralights." The AUA's address is P.O. Box 2287, Ogden, Utah 84404, (801) 621-3941.

For Professionals Only At the Tullahoma fly-in, a meeting among the various ultralight manufacturers to discuss FARs and other points of interest developed into the beginning of a new organization, the Professional Ultralight Association. Just as the EAA Ultralight Association and the AUA were formed to represent individual ultralight enthusiasts, the PUA is being formed to provide a

the aircraft will not be subject to FAA certification, nor will the pilot be licensed. Notice, no mention of foot-launchability. There will probably be some airspace use limitations. In my discussions with various FAA officials, I have repeatedly told them that hang glider pilots will accept no more airspace restrictions than currently applied to a non-radio-equipped, conventional aircraft. They seemed willing to accept that. They do not seem to want to even contemplate the possibility of splitting out foot-launch from power. Several pilots have told me about being "hassled" by their local FAA GADO (General Aviation District Office). In some cases, the pilots were at fault. (It isn't too intelligent to hassle people with your flying, no matter what you fly.) In other cases it appears that the local FAA officials don't know what to do because there are no "real" regulations at the present time. If you're threatened by your local FAA office, and you're not doing anything stupid, like flying at night without lights or flying into restricted airspace, gently explain to the FAA types that the national office of the FAA is working on an NPRM and that your aircraft is legal under the current understanding of foot-launchability. Be reasonable; four-hundred-pound aircraft are not what we're talking about. If the local GADO troops insist on giving you a rough time, call me. I might be able to help. Les King (301) 840-9284

Election Results The ballots from the mail election to select nine Regional Directors with twoyear terms to run through December 31,

unified voice for the manufacturers. Seven manufacturers have signed up and Lyle Byrum of Eipper is the acting president and Tracy Knauss, publisher of Glider Rider is the acting secretary I treasurer. Knauss is currently working on incorporating the PUA as a non-profit organization. Knauss says the organization will do some of the same jobs as the HGMA does with hang glider manufacturers, but they don't want to get into comprehensive flight and structural testing yet. However, they do plan to provide some consumer services, such as hearing complaints about faulty products and such. Membership fee is a hefty $250 annually, but for manufacturers, it may prove worthwhile. ....

HANG GLIDING


Dear Jim and Henry, On July 25, 1980 two llritlshers, who attempted records at Cerro Gordo for 10 days straight, plus Chris Aro!, o top notch U.S. pilot, ond George Worthington launched from Cerro Gordo about 1 :30 pm. All four were trying for the World Flex-wing (P.ogallo) Distance record. It was a special day because of the location and excellence of the cumulus clouds. The Mego climbed straight to cloudbose at 16,500, directly over toke-off. I allowed the Mego to enter the cloud until vision directly downward was starting to fade. Then I pushed the control bar toward the knees Just enough to mointoln downword vision. There was extro speed left, if needed, at oll times. When the edge of the cloud wos reached the Mego was slowed to minimum sink speed and steered to the next cloud ahead. The Mego's sink rote helped to get the glider to the next cloud at o height where the thermal underneath was still very active. When the second cloud was reached, the some procedure, as used in the first cloud, was repeated. The Mego flew 60 miles like this, from cloud to cloud. :The Mego offered a unique advantage on this flight. Many of the clouds were as muc:h as one and two miles "behind" (downwind) the spine of the mountain. With the Mego's better speed range ond penetration, it become reasonably safe to fly such o distonce behind the spine and toke advantage of these clouds. It mode on extremely significant difference In achieving the record. At the 70 mile mark, the Mega was under o solid overcast which stretched ahead for 15 miles. It looked bod because no heat was getting through to the volley floor or to the sides of the mountains. And it was bod. Every scrap of lift was used but the glider was forced lower and lower. At the 85 mile mark, at 8,000 feet ASL 1500 feet above the oluviol fan of the volley floor) the er finally flew out from under the overcast and over a s eer rugged rock canyon wall facing the sun. A violent, snakelike, thermal existed right next to the wall. The Mego hod to fly within 50 feet of the woll or lose the thermal. The turbulence was violent. I put my faith in the reputation of Moyes and the llraddocks that the glider was strong. After long minutes of thrashing around, trying to catch pieces of the "snake" that was going up, (you could never stay in the lift for more thon o quarter turn) the altimeter began inching up. Finally, the "snake" become a reol thermal, and took the Mego up ta 16,500. From there, in a straight glide, with no real thermals, but with the help of some buoyant cool evening oir, and o bit of downwind toilwind component, the Mega glid!l'd 23 more miles and to a new World Record.

BIRDS IN FLIGHT s;gg;~._/~ Illustrations and text © 1980 by Dennis Pagen In a few short generations, our species has overcome ageless limitations by venturing into the cool expanse of the sky. We are now free to explore the realm of the birds. Powerful engines, gleaming fuselages and silver wings can carry us to great heights at wondrous speeds, but only hang gliding truly resembles bird-like flight. Several weeks ago I rode my glider in a thermal 2,000 feet above the hilly terrain. I was concentrating on centering in the lift, when a flicker of motion caught my eye. Looking up, I saw a little Broad Winged Hawk (Buteo Platypterus) maneuvering about three feet in front of my glider's noseplate. He stayed with me for almost four circuits before sailing off to better lift. Soon, he was well above, leaving me to marvel at his grace and flying expertise. This was the closest I had been to a soaring hawk, but not the first time I had appreciated their beauty and skill. As a child, I envied their ability to enjoy the rapture of the sky. I became an official bird watcher when I joined the Audubon Society in 1960, but it wasn't until I began hang gliding that I truly learned to understand the hawks on their own level. Today, I view the soaring birds as teachers and mentors. They have a willing student. I believe that eventually we will come even closer to the mastery of the air displayed by the birds through our increasing practice and improved glider designs. To reach this ideal, we must watch our feathered friends with a keen eye and acquire their secrets through unspoken communication. We must create wings that embody the essence of bird wings. We must learn their intuitive methods of exploiting lift. This pictorial study is a brief introduction to the function and control inherent in a bird's flying apparatus. Certainly, the more we know about the birds' efficient mode of flight, the more readily we can improve our own primitive ventures into the sky. With new materials and insights, perhaps we can ascend to the birds' level of performance and achieve even greater beauty and freedom. .,,.. 16

HANG GLIDING


In the United States during the early ] 960s hang gliding was conducted by a few individuals in sections of the East and West coasts. The kites were usually constructed of bamboo and plastic. Design and construction of the machines was given a boost by a series of experiments in flexible wings conducted by the National Aeronautics and Space Administration in the late 1950s to middle 1960s. The wings were being considered as possible vehicles for returning space capsules to earth, but the effort was abandoned in favor of utilizing parachutes. By the early J 970s aluminum and dacron sail cloth were the standard construction materials. The increased strength and durability provided by this combination allowed a series of design and manufacturing advances that helped set the stage for the sport's explosive growth.

The official journal of the sport is Hang Gliding, published by the United States Hang Gliding Association (USHGA). Hang Gliding is descended from the newsletter of the Southern California Hang Gliding Association (SCHGA), Ground Skimmer. The newsletter was first issued in May, 1972. SCHGA began as the 25-member Peninsula Hang Glider Club in December, 1971. Within a few months it attracted many members across the state and the name was changed to reflect the wider membership. Favorable mention of SCHGA and its newsletter by a number of national magazines led to a substantial increase in membership nationwide. By November, 1973 more than 4,000 people were members and newly formed hang gliding clubs across the country asked to affiliate with SCHGA.

On November 13, 1973 the directors of SCHGA voted to change its bylaws to become a national organization, and change its name to the United States Hang Gliding Association. Members ratified the proposal on December 18, 1973. Annual election of officers and directors for the new organization was held during January, 1974. Lloyd Licher of Los Angeles, CA was elected as the association's first national president. USHGA bylaws were further changed on November 18, 1974 to provide for election of board members from geographic regions. The first meeting of the newly reorganized board was held September 27 and 28, 1975, in Denver, CO. The number of directors

COMPETITIONS The first national hang gliding meet was held July 1, 19'73 at Nags Head, N.C. National championships, firsl held July 11--15, ·1973 in Sylmar, CA, are conducted annual-ly by USHCA. Regional meets are also sanctioned by USHCA. The topperforming pilots arc authorized to repre·· sent their region at national championships. The Masters, an international invitational meet sanctioned by USHGA is held annually the third week in September at Grandfather Mountain, N.C. The first world championship was held September, 1976 in Kossen, Austria. World championship competition is held every other year in odd·-number years.

INTERNATIONAL HANG GLIDING eligible to serve on the board from each of ] regions was determined by the number of USHGA members residing within the region, a system that remains in use today. USHGA offices were established in Los Angeles. The mailing address is P.O. Box 66306, Los Angeles, CA 90066.

SELF-REGULATION Recognizing the need for self-regulation to improve the sport's safety rcocrcl, USJ--!GA issued a series of regulations affecting flyers, instructors, schools and flight equipment. A flyer rating system was first published SCHCA in June, 19'73. The USHCA system was established in March, 19'75 and provides for five levels of pilot proficiency. Requirements for instructor training and certification were also issued. These requirements arc reviewed and updated periodically. USHGA-certified schools and appointed members help administer the programs. Hang glider manufacturers formed the Hang Clider Manufacturers' Association (HM/\) on January rn, l 974. Later reorganized as the Hang Glider Manufac. turers' Association (HCMA), it operates a system of certification for hang gliders meeting HCMA standards of performance safrty. Only certified hang gliders can be used by flyers in sane I ioncd competition. The Federal I\ via ti on Administration (FAA) issued an Advisory Circular dated May 16, ·1974 regarding recommended safety parameters for operation of hang gliders. This document has been reviewed by the FAA and continues to serve as guidance to the sport. Hang gliding's self-regulation through USllGA continues to work effectively to improve the sport's safety record and operations.

The international hang gliding commission of the Federation Aeronautique Internationale (FA!) is the Commission Internationale de Vol Libre (CIVL). The CIVL held its first provisional meeting in Paris, France on June 26-2'7, 19'75. The F/\1 Ceneral Conference of September, 19'75 approved 2stablishing a hang gliding commission. CIVL's first official meeting was held in Paris, November 26-27, 19'75. The creation of C!VL marked a change in USHCA's relationship with the National Aeronautic Association, upgrading USHGA's status from affiliate to division. USHGA is thus recognized by NAA as the only organization in the United States authorized to sanction national championship contests, sanction attempts for national and world records, and carry out F/\l responsibilities delegated to it by NAA.

HANG GLIDING


OFFICIAL RECORDS Design improvements have changed the appearance and performance of hang gliders. The "standard" Rogallo kite featuring narrow nose angles of less than 80 degrees and billowing sails, with consequential low performance, has evolved into flying-wing shapes of larger nose angles, tighter sails, double-surface wings, keel pockets, battens and other devices that provide increased performance. Most hang gliders have retained the quick set-up and portability features of the earlier generations. Improvements to hang gliders are reflected in the official records established this year. The 100-mile distance barrier has been broken, and altitude gains of over one mile have been achieved. As the hang gliding section (Class 0) reveals, the United States currently holds all official records in the sport. THE PAST INFLUENCES THE FUTURE Hang gliding occupies a spectrum of flight performance that was investigated at the beginning of modern flight in the 1890s and early 1900s. The reopening of activity in this long-neglected sector brings aviation full circle. Renewed interest is having an influence on aviation. The international prize-winning series of manpowered "Gossamer" aircraft were based on hang gliding manufacturing, design and pilot training techniques. National and international sanctioned competitions and official record activity will help insure the continued development of this oldest and newest method of flight. The future holds much promise for this rapidly evolving sport. Its advancements will be reflected in the pages of this ~ publication.

MARYLAND: Mario Manzo of Kettering, Ohio took his own design, a bowsprit prototype, over into Maryland for a memorable flight which included Mario's highest altitude gain so far. At Cumberland, MD, he went eight miles cross-country and gained 3,500 feet above takeoff. The 32-year-old photo technician has spent several years going for airtime in the 200 to 400 foot hills of Ohio, and it looks as though it's paid off. NEW YORK: Flight #75 was the magic one for Mike Cimino of N. Syracuse, NY. On July 13, 1980, the 24-year-old took off from a 350 foot hill in a half-mile wide valley. He gained 700 feet in thermals, using his vario for just the third time. His comment: "I felt at home in my SST." PENNSYLVANIA: David Grindel, 22, of Freedom, PA put lots of time on his Hang II rating with a flight of 3 hrs. 35 min., setting an endurance record for the area at the same time. David flies an Alpha. FLORIDA: An Advanced pilot with six years of hang gliding experience now holds the Florida State record for distance. Ray Foley, 35, of Tampa, Florida made the record 21-mile distance in a two-hour thermal flight on his Atlas. For flatlands flying, that's amazing! NEW MEXICO: An Albuquerque pilot, Mark Ostrower got to see some special scenery while in flight, on the way home seven miles from launch. At 10,000 feet msl, he and his Spirit passed over a Fighter Squadron, out on maneuvers.

I just love rural airports at night when no one is around except the ghosts of past flights who whisper their stories in the gen·· tle night breezes. We took the Pterodactyl engine out of the small camper and laid down to wail for morning and the other six ultralights. The July sun was just beginning to lighten the sky when the first of the other gliders arrived. Soon the ramp was crowded with Pterodactyls, engines, instruments, gas cans

and spectators. The plcm was to fly from New Cuyama, California, lo Taft for fuel, then Bakersliekl. We would return that evening if the weather allowed. TV and newspaper reporters had promised to be at each of the destinations. The round trip measured l 20 ground miles. By 8:30 a.m. the sky was dotted with circling ultralights. The last one took off and the group headed cast. Due lo the flip of a coin I had ended up driving a ground support truck fur the morning flight, then would fly the return legs while my partner, Mike, drove. Being on the ground is a whole different adventure from flying. It was common to pass stopped cars on the sparsely populated highway, their occupants staring skyward at the invasion of strange tailless wings. We counted the planes about every five minutes to keep track of everyone and checked in with a flight report, "smooth air, engine is a little rough, running low on fuel." Mike had circled a long time waiting for everyone lo leave New Cuyama and was realizing that he might not have enough fuel to make the Taft airport. His new engine was not running well and wasn't fully broken in yet. He was the last to touch down at Taft and the fuel line was full of bubbles as he taxied to the crowd of local people who were surrounding the other planes. The local reception was really great. The Taft people were pleasant and curious. We refueled and laid a course lo Bakersfield over Buena Vista Lake which is known for recreational boating. Some of the guys got quite low over the lake and by the time we all left, many of the ski boats showed red flags which indicate a fallen skier. Since the highway took a round--about route, the Pterodactyls got to Costerisan Parms, Bakersfield, sooner than we did in the ground truck. We arrived just in lime to sec the six gliders land smoothly on the 1,000-foot grass strip and it was after the last propeller slowed to a slop that the ll 8 ° heat surrounded us. The only thing that saved our minds and spirits from the oppressive heat was the tcr-rific hospitality shown lo us by Mr. Costerisan and his staff. He offered us full use of his lake, fresh peach punch and sliced watermelon. Soon the lake was full of pilots who were intent on disguising themselves as ducks. The idea was to be able to join the local flock since the ducks clearly had the best lifestyles for such a steaming day. The ducks were prct ty smart, though. They must have been able to tell the real ones from the people ones by the shape of the paper cup beaks. The game was abruptly

ended when the TV and newspaper photographers arrived. There seems to be an unwritten rcquircrnent for a pilot's rating which reads, "He shall demonstrate that he is a ham and show-off before any and all cameras." The lake was suddenly void of all but the ducks and soon the sky was full of Pterodactyls. Formation fly-bys with sequential pull-ups dazzled the photographers who had come from the local newspaper and TV stations. Cramped by the limits of the video camera's tripod, the TV cameraman grabbed his shoulder cradle so he could shoot straight up, lo the sides, and even bend backwards.

then, as we approached Taft. The Taft wind was 90° cross to the only nmwc1y so we landed across the asphalt and used the bordering weeds for brakes. This visit lo Taft was more brief and not so glorious. We were feeling the effects of the heal and most of us were anxious to fly on to our point of origin which necessitated a 1,800-foot climb. We refueled with avgas and when we left the ramp, my Pterodactyl effortlessly climbed lo 4,000 feet ms] where the temperature was much better. Noting the unusually excellent climb rate, I chose to throttle back and be as fuel efficient as

When we were asked if anyone minded the station using some of these shots as background for station idcntifica-lion and news shows, I don't remember anyone objecting. After a drive to the local deli for some prepackaged sandwiches and Gatoraicl, we departed the traffic pattern to the west, into the wind. The 3:00 p.m. air was predictably rougher and the wind slowed our ground speed although it was somewhat cooler at 3,000 feet msl.

The 4,000-foot glide back to New Cuyama (engine at idle) was a pleasant way lo end this adventure and, after landing, the only pressing issue was to quickly break down and get lo Jerry's for margaritas and steaks.

BLUE STRATOS Power and Towing CHAMPIONSHIPS Article and photos by Keith Nichols

-

For years now, hang glider pilots have been looking for some kind of contest sponsorship . It's long been felt that the sport will never rea lly take off or achieve public acceptance without ma jor, sponsored competition . So you can imagine my elation when a PR firm in ew York City called me and said they had a client who wished to sponsor two hang gliding tournaments . Visions of all the spectacular sites I'd flown waltzed through my head as I asked where they wanted them . The waltz came to an abrupt end, however, as I was told they would have to be in Atlanta, Georgia and Dallas, Texas. Shulton, Inc. , the makers of Old Spice and Breck, were introducing a new men's cologne and after shave called Blue Stratos and the 19:30 test markets were to be Atlanta and Dallas. The client wished to see how well hang gliding could generate publicity. The only problem that he failed to consider was that neither city had any significant mountains. Alternatives would have to be found .

TOP: The lineup for launch. ABOVE: USHGA Director Dick Turner gets his Eagle ready.

In Atlanta, I got together with Doug Lawton, a long-time professional tow pilot, and we put together a tow kite contest that was held at Callaway Gardens, Georgia, about 1 1 2 hours south of Atlanta . For Dallas, I recruited Gary Scheer and Jerry Kitchens at Lone Star Hang Gliders, long time power advocates, and we set up the first professional powered hang gliding contest, to be held at Air Park , North Dallas. We were fortunate in Atlanta in attracting many of the top competitors from the Cypress Gardens Tournament. We designed a threefold task using reversing 360's, an alternating gate crossing (LID) task, and a target splashdown . The competitors had to decide when to stop the 360's and go for the gates, and then when to leave off and set up an approach. After the pilots spent Friday for practice, five rounds were flown Saturday and Sunday for the $5,000 purse. A seeding system was used that constantly moved the better pilots up to fly against the other better pilots. By the fifth round, T.J . Beatty had moved into first , followed by Robert Bailey, Matt Wagner, Matt Bablitz, and Campbell Bowen . These five were battling it out for the big money. However, round five had a few surprises. T .J. had an upside down landing, knocking him down to fifth ; Dave Ledford, with a very high-scoring flight, moved up from 11th to fourth ; Campbell slipped down to eighth and Bruce Pemberton moved into third with a perfect score, 3, 100-point flight. But the real battle was between Robert Bailey and Matt Wagner. Robert was 208 points ahead of Matt going into round five. Matt went for the maximum 360's getting 1,000 points, leaving Robert with 800, but Robert took the gate crossings for his 1,000 giving Matt 800, still tied in the task going for the landing area . This was when Matt turned on . Robert landed only a few feet from the target but Matt planted his feet


dead center in the innertube to pick up not only 1,000 points to Robert's 750, but also a 100-point bonus for the bullseye. Gaining 350 points on Robert, Matt moved into the winner's circle, taking the Blue Stratos Tow Championship and winning $1 ,500 along with a 15-inch high carved Lucite trophy . In Dallas, we were both surprised and pleased when David oell offered us his AirPark for the weekend . The facility allowed us lots of controlled spectator room, an excellent runway, and tie-downs for the gliders . Through the efforts of the Lone Star people, this contest turned into a full-scale air show. The program each day was opened by a parachute team landing right in front of the crowd, the U.S. ational Aerobatics Champion put on an amazing show in his Pitts Special, the old farmer-steals-an-airplane-and-flies-away-out of-control stunt was staged, and there were flybys and displays of a VariEZ, a 1917 Curtis Pusher, and others. The competition consisted of six rounds of three different tasks. Task one was a race around a pylon course with a minimum altitude restriction . Task two was a double bomb drop from 50 feet. For task three, each pilot was given one quart of fuel and told to stay up as long as possible. Tasks one and three had accuracy landings on the runway as close to a set line as possible. Task two only required that the pilot land on the runway . In Saturday's pylon race, competition experience seemed to give an edge. American Aerolights factory teammates Gil Kinzie

and Barry Gordon turned in the fastest time of the day on their Eagles: 4 min. , 41.08 sec. and 4 min ., 54.39 sec . However, the next day, Terry Pressley blew everyone away with a time of 4 min ., 18.53 sec. There was no question that he had learned what to do. The bomb drops provided some comic entertainment. The first time around, Tom Peghiny amazed the scorekeepers by placing both of his bombs exactly 21 feet, 8 inches away from each target. Now that's consistency! But he was beat that day for the high score by Barry Gordon with drops of 12 feet , 6 inches and 14 feet, 6 inches. This was from 100 feet. For Sunday, the

drop altitude was lowered to 50 feet. T his day, the Quicksilver pilots shined. Bob Grassl not only got the best total score of the meet, he got the closest single drop : 5 feet , 8 inches. Tom Peghiny and John Lasko were right behind him, both with drops closer than 10 feet. The third task of each day proved to be the most challenging. O ne qua rt of fuel was the most a pilot could have and the object was to stay up as long as possible. National and World Champion Rex Miller, flying for Manta Products, had the best duration Saturday by keeping his Soarmasterpowered Fledgling in the air for 15 min.,

TOP: Launch. Note the steep climb. ABOVE: Jerry Welch on the launch deck.


45.39 sec. His closest competitors were Terry Pressley with his Easy Riser, Gil Kinzie, and Eipper factory pilot John Lasko, all over a minute behind Rex. Once again, however, Terry showed that he was a good student. When this task was flown on Sunday, Terry racked up an impressive time of 18 min., 28.06 sec. in bumpy, crosswind conditions, beating Rex this day by just three seconds. The two of them were more than four minutes ahead of their nearest competitors. By the end of the third round, Pressley, Gordon, Lasko and Loren Prescott had firmly established their leads in that order. The rest of the standings changed with each round but after all six rounds, it was Terry

Pressley and his powered Easy Riser solidly in first place with 5,621 points.

I managed to stay very dry and enjoyed eleven of the cleanest, coolest, most dirt·· free flights I'd had in a long time. The guys got about eighteen. After the day was over I really felt good about my superman takeoffs, the chance to feel the thrill of free

flight, and the eleven opportunities to practice my shaky spot landings. Towing certainly is an exciting way to hang glide with a bit of a twist for a change of pace. For those of you who think you need to be strong or think it's too dangerous I suggest you don't let rumors or bad press scare you off. Towing has come a long way and with someone like Peter Brown at the controls you know you are in good hands.

be from a load test (preferably before flying it).

I think deflexorless leading edges are the greatest thing since the Flexi Flier definitely a step in the right direction from a design standpoint. Essentially two reactions support the leading edge at the crosstube and noseplate. Such a simple structural system lends itself to numerical analysis. This is not the case with a bow-sprit leading edge which is virtually impossible to numerically analyze because of all the cable attachment points. The only way to determine the deflection characteristics of a bowsprit leading edge under flight loads would

On the other hand, the deflexorless leading edge bending moment distribution can be determined from statics (Figure 1). If the stand-up keel pocket is assumed not to carry any of the flight loads, then the leading edges carry it all, and the problem becomes statically determinate resulting in loading, shear and bending moment diagrams like in Figure 1. To get the precise solution, a special loading test must be done to determine what share of the flight loads the stand-up keel pocket is taking. The interesting part of the solution is that

there is an optimum deflexorless leading edge design for a given sail planform. If the crosstube/leading edge junction is too far out on the leading edge, the bending moments become excessive between the noseplate and the crosstube causing the leading edge to collapse. If the crosstube is too close to the noseplate, the tip breaks off. This optimum crosstube reaction point location is a function of the sail loading and isn't difficult to calculate for a deflexorless leading edge.

Mean Camberline Profiles (Batten Shapes) Mean camberline profiles (batten shapes) are pretty straight forward for an JANUARY 1981

camber. So if I ever get back into the jet engine business, I'm all set with that profile. I've actually seen the second batten shape on some hang glider tips, although it is kind of inefficient because it generates a negative lift coefficient of - .35, but has a positive pitching moment of + .1. The next three batten shapes are mean camber lines that I consider usable on some hang glider designs. All three shapes meet the HGMA positive pitching moment coefficient specification of + .05. The value of lift coefficient created by the profile itself is peanuts, and in order for a typical hang glider wing to generate a lift coefficient large enough to lift the gross weight, it has to generate lift through angle of attack. So the only purpose of the batten profile is to insure that the free-stream flow meets the leading edge smoothly over a wide angle of attack range and flows over the wing in such a fashion that it generates a positive pitching moment. This isn't always the case in some batten profiles. Some battens don't have reflex as in Figure 2, but have straight backs. This shape has a negative pitching moment, although it's small; so small that they are popular for helicopter blade profiles (Reference 4). With enough tip washout, the wing could be made positively stable with these negative pitching moment profiles.

aerodynamicist to calculate (Reference 6). Unfortunately the theoretical batten shape may have nothing to do with reality. The first profile in Figure 2 has a 2-D lift coefficient of + .75 and a positive pitching moment of + .1. Unfortunately it has too much camber for a hang glider application because of separation off the bottom and top surface. I haven't given up entirely on it though. It might work for a high-pressure turbine nozzle profile. In a typical fighter jet engine the pressure may drop by four or five atmospheres across the high-pressure turbine. Turbine nozzles have what is known as a positive pressure gradient as opposed to an adverse pressure gradient. The flow is literally sucked around the blade without separation, regardless of the

There are a couple of ways to get rid of crosstube drag area - either by hiding it like the Comet or Sirocco or by using fairings. There are some structural problems with hiding a crosstube and fairings are great if they are at the right angle of attack, although fairings are a hassle to pack up after flying. A real novel approach to crosstube drag reduction is tripping the laminar boundary layer on the crosstube to a turbulent state (Figure 3). The turbulent boundary layers can negotiate the trailing edge of the crosstube more efficiently than laminar ones, and as a consequence, the separation region on the backside becomes much narrower. This is the precise reason golf balls are covered with turbulator pits. They just go much further. The tricky part of doing it for a hang glider crosstube is that there is an optimum grid roughness to crosstube diameter ratio for a particular flight speed (Reference 3). At low flight speeds the turbulators don't do much for you, but at high flight speeds, since the parasitic flat plate drag area of the cross tube is 30 % to 40 % of the total, the proper choice of grid roughness could reduce the drag on the crosstube 35


by a factor of three or four, which isn't too shabby. The turbulators have a great angle of attack range ( ± 45 °) and should pack up conveniently.

Multiple Coplaner Wing Planform Designs The big difference between flying wings and monoplane, canard, or Montgomery wing designs is that besides the induced drag of each individual wing, there is the interference drag of the front surface upon the rear surface. It is sort of like designing a biplane; if the two wings are sandwiched closer than a chord length, serious flow field interference occurs between the two wings. This interference phenomenon is twice as serious in biplane design because both surfaces interact with each other, but in coplanes, monoplanes, canard and Montgomery wing designs only the induced interference of the front surface is convected over the rear surface. The interference calculation is something like the interference calculation for a biplane, but a coordinate transformation is performed (Reference 7). The resulting interference factor is plotted in figure 4. The actual interference drag between the two surfaces is: D,, = SPAN,)

hang glider. Variable geometry usually implies large in-flight wing planform changes, but in hang gliding, in-flight billow and C.G. adjustment would probably suffice. The variable geometry concept is sweeping up in sailplane competition. John McMasters, apparently the next Low Speed and Motorless Flight Symµosium warlord and master of ceremonies, wrote a series of articles in Soaring magazine which discussed the incredible performance capabilities of variable geometry sailplanes. Essentially the pilot could dial in 50% span increases, 50% chord increases, and camber increases. He could dial in whatever LID, sink rate or flight speed he needed for flight conditions. There is one small problem with variable geometry sailplanes, however. A good German one goes for 500,000 marks,

implying that all the people winning the competitions are either rich or sponsored. I think this is a pity. Hang gliding doesn't have this problem, though, so I don't think variable geometry hang gliders will be outlawed from competition because of prohibitive costs. Variable geometry hang gliders aren't a new idea. I remember talking to Tom Peghiny a few years ago about having an in-flight expandable crosstube for billow adjustment. There is reference to it every once in awhile in the technical literature. Reference 6 describes the exciting possibilities of varying the cable trailing edge tension in-flight on Princeton Sailwings. The advent of the floating crosstube in hang gliding has exciting variable geometry possibilities. Without too much imagina-

So the actual interference drag is a function of how the surfaces are loaded, and also their spans. The important thing is to get the interference factor ( er ) small, because it's just multiplied by the whole mess. To minimize the interference, the wings have to have their aerodynamic centers separated by a tolerable distance (1 in Figure 4). For example, a good Montgomery wing design (front span, B,, equals rear span, B2 in Figure 4) has the front and rear spans separated by a semispan. This amounts to having '1] , the non-dimensional separation distance in Figure 4 greater than .5. The same calculation can be done for Quicksilver monoplanes and Eagle-type front canard designs. Just calculate '1} and if the interference factor, er , is .1 or lower, you probably have a pretty clean multi-surface design.

tion, a floating crosstube could be designed for billow variation by merely moving the pivot point fore and aft. The glider could be trimmed up for 360's by merely moving the pivot point left or right. The design of the adjustable crosstube is a mere mechanical engineering problem - definitely beneath an aeronautical engineer. If this pivot adjustable crosstube could be coupled with a variable pilot C.G. attachment point, the glider would have incredible performance capabilities. The pilot could tighten up the sail for cross-country work, or loosen the sail for minimum sink capabilities. The day of the flex wing is coming. Because it is very difficult to make a variable geometry rigid wing (Fledge, Quicksilver, etc.), the variable geometry flex wing eventually could out-perform rigid wings.

HIGH

Iii

Have you ever been in the position of gaining gobs of altitude, so much so that the possibility of hypoxia seems at hand? At what altitude would you be affected? What symptoms would you have? Could you recognize the symptoms? What effects would these symptoms have on you? What can you do (or stop doing) to reduce the effects of hypoxia on yourself, or at least postpone them for a higher altitude? You can answer these questions and more by participating in a session of physiological testing sponsored by the FAA and the U.S. Air Force. Four Arizona Hang Glider Association pilots recently participated in one of these programs at Williams AFB, near Phoenix. On Sept. 10, 1980 Miles Fagerlie, Hans Haydrich, Phil Richards and Bob Thompson, along with 16 other pilots, both private and commercial, spent 7 1/2 hours learning about flight-related physiological problems, including hypoxia, hyperventilation, the bends, night vision complications, spatial disorientation, trapped gas

and evolved gas disorders, central nervous system (CNS) disorders, self-imposed stresses, and more. Anatomy and physiology of the inner ear, eye, lungs, circulatory and digestive systems were carefully explained so we could understand not only what the physiological problems were, but also what causes the problems and how can we as pilots counteract or postpone them. Much of the information on hypoxia and hyperventilation presented in the physiological training session has previously been elaborated upon in an excellent and informative article by Alan Reeter: "To Breathe or Not to Breathe." Rather than duplicate his article here, I'll leave it to you to go back to the February 1979 Hang Gliding and read it for yourself. We arrived early, not wanting to miss anything. The program began promptly at

8 a.m., as one might expect at a military installation. Most of the morning was spent in lecture sessions, with the baromey chair demonstration being the only time we actively participated in the program. Hans volunteered to be the guinea pig in the baromey chair. Blindfolded and slowly rotated in the chair, Hans became disoriented, as a pilot might in a cloud. When he moved his head perpendicular to the rotating movement, as we might while looking around in our gliders, he suddenly became violently disoriented, which, if he had been piloting a plane or glider in a cloud would have undoubtedly resulted in an uncontrolled spin or spiral dive. Anyone interested in flying in clouds would be well advised to take a baromey chair ride first. After lunch at the Officers Club we returned for another short lecture, then donned red goggles in a dark room to prepare us for a session on night vision complications. The wide range in individuals' physiological capabilities first began to surface in this test. There were few owls amongst us. A few bits of information which I found especially interesting in our lecture were: 1. Gin and tonic destroys part of the inner ear. This could aggravate any equilibrium/ disorientation problems a pilot might get into. 2. Marathon running and jogging is hard on pilots. This slows down heart beats and lowers blood pressure - just the opposite of what you need at high altitudes. 3. Carbon monoxide is attracted 250 times more to blood hemoglobin than oxygen. Think of that next time you ride in the back of a truck or camper on the long drive up to your favorite high launch point. 4. Make sure the water level is up in your body. Coffee, tea, colas, Gator Aid, beer, etc. add liquid to your stomach, but because of their chemical makeup (acidity, salts, etc.) they reduce water levels in your blood. For best results, drink water. 5. Within a 24-hour period don't mix scuba diving and high altitude flying of any kind, commercial or hang gliding. This may cause an evolved gas problem which could seriously incapacitate you. 6. Stay away from beans, carbonated beverages, and other gas producing foods prior to high flights. A lowering of the pressure on the outside, as you gain lots of altitude, allows for greater expansion inside. The trapped gas problems which could result might not feel too pleasant. (On the other hand, maybe a taco thermal might help keep you up in marginal conditions!) While we were at 25,000 feet in the altitude chamber numerous double flutter blasts were emitted. Handily, there is a rapid air HANG GLIDING

exchange in the chamber and no nasal passages were offended. The high point (take that however you wish) of the program was at the end of the day, about 1/2 hour in the hypoxia cham·· ber. We were split into two groups, allow·· ing us to observe others while our minds were functioning normally. We were carefully briefed on what to expect and look for, fitted with oxygen masks, and the massive vault-like door was shut. First, we went up to 10,000 feet and checked all the people and systems. A few adjustments and we were off to 25,000 feet. Ears popped, some eyes blinked nervously, and we were there. Now for what we primarily came here for off with the oxygen masks. Our bodies were now in the same pressure and oxygen percentage equivalent to flying at 2.5,000 feet. Conditions were optimal, however, as the temperature was comfortable, we had not physically horsed our gliders around to get that high, and stress factors were almost non-existent. We also had highly trained personnel in the chamber with us (they stayed on oxygen) and outside (controlling everything), who JANUARY 1981

could advise or help us with any situation, including mental or physical distress. We were given a sheet of paper with various mental tasks to perform. In one to six minutes everyone showed some signs of hypoxia, some sooner, some more prominantly. It was fascinating! Several people looked like they were in a drunken stupor, some looked almost hyper, a couple were euphoric, some hand writing got very sloppy, some people failed simple arithmetic problems (2 + 4 Tl), some had recall problems. After six minutes I was still able to write and do math just fine; the only symptoms I was aware of was slight tunnel vision and deeper breathing. Upon coming out I was informed that I showed a pronounced blueing around the mouth and fingers. Our trip to 25,000 feet had been very educational. We all experienced some hypoxia (under safe and controlled conditions) and were able to sec, feel, or be told about how each individual showed signs of hypoxia. Many of the questions I presented in the beginning of this article had been answered. One last experience we participated in

was a rapid decompression such as might be experienced in a pressurized aircraft when a window or door blew off. This certainly would not pertain to hang gliding, but it was interesting, nevertheless. Ears pop·· ped, the temperature plummeted, and the air fogged up. The vault-like door was opened, we removed our masks, and the day's activities were over. As I sit here writing this article, looking over my notes, and thinking of our experience, I am still amazed at how much information was presented in one day. It was definitely time and money well spent.

GENERAL METEOROLOGY: PART I Introduction to Global Circulation by Rick Jesuroga Rick Jesuroga is a 25-year-old hang gliding enthusiast and meteorology student at Metro State College in Denver, Colorado. A former ski addict, Rick moved from Connecticut to Colorado in 1976 to take in some western powder, saw a Sun Swift fly off Lookout Mountain in Golden and started lessons the next day. Rick continues his studies at Metro State with a specialty in thunderstorms, and instructs the blind and handicapped ski program at Winter Park, Colorado. The National Center for Atmospheric Research is located about 20 miles from his residence and provides an excellent source of information. This is the first in a five-part series broken down as follows: PART 1: Introduction to Global Circulation PART 2: High and Low Pressure Systems PART 3: Divergence and Convergence Aloft PART 4: Warm and Cold Fronts and Cloud Types PART 5: Lifted Index and Soaring Forecasts In the Denver area meteorology is a prominent field of study, with the National Center for Atmospheric Research (NCAR), the National Oceanic and Atmospheric Administration (NOAA) and the National Oceanic and Atmospheric Survey, all located in the Denver Metro area. Rick's series should certainly prove enlightening and informative. -Ed. JANUARY 1981

Ever since recorded history, man has been bewildered by the sky and the stars. Ancient cultures believed the weather was controlled by gods and the heavenly bodies. Amazingly so, today some hang glider pilots still believe in thermal wizards

and invisible dragons. I think Galileo would roll over in his grave if he heard some of the explanations of weather-related phenomena by the average hang glider pilot. Only a few years ago while in a desperate effort to get out of the flush, I would yell "Help Mr. Wizard," as I was certain some non-terrestrial being pulled the plug. After lots of scary flights and many fruitless screams, I decided it was time to learn more about this new element of which I was at-

biners. Recent glider design innovations and pilot eduction have provided us with flights of over 18,000 feet and over 100 miles. As this trend continues, it will become important for us as pilots to be more familiar with the elements of our atmosphere and less dependent on the wizards. The cumulative content of this series of five articles will help enhance your knowledge of our atmosphere, unfolding the secrets of the sky. You must remember 41


that I can only touch on areas I feel will be of importance to you. Research in more detailed areas will be left to the interested reader. Before we can understand the flow of the atmosphere and how forecasting is accomplished, it is important that you have a general understanding of the global circulation. Of course, the atmosphere provides us with the necessary elements to survive. Air is a mixture of several gases. The most abundant are nitrogen 78%, and oxygen 21 % . The remaining 1 % is made up of argon, neon, helium, carbon dioxide, ozone and water vapor. Without this precious mixture, humans wouldn't survive. The atmosphere, however, was not placed here for our survival; we are a mere by-product of our environment. The atmosphere was produced long before man or woman. The atmosphere provides a method of transporting hot and cold air. Without this circulation the poles would freeze over forever while the equatorial regions would boil indefinitely. The global flow will show us how this circulation is accomplished. Initially the atmosphere is set in motion by the imbalance of solar radiation from the sun. As the equator receives more direct rays from the sun than the polar regions, intense heating at the equator causes the air to become less dense and rise aloft. Cold, dense air above the poles descends to the surface and flows downward toward the equator replacing the rising warm air. Here we see our single cell theory (see Figure A). First, we'll define a cell as an area enclosed by arrows showing the circular air flow. Here we see a cross section of our atmosphere. The single cell theory only exists in theory. Illustrating only one cell in each hemisphere, it shows the initial movement of hot and cold air. The triple cell theory gives us a more realistic illustration of actual air currents. From this point on, we will deal with the northern hemisphere alone. The southern hemisphere is an exact mirror image of what takes place north of the equator. The triple cell theory is the result of the earth's rotation on our single cell. The rotation of the earth has a different effect on the atmosphere at different latitudes (see Figure B). For illustration, note carefully the paddle wheels drawn on the equator and the north pole. As the earth rotates, the paddle wheel located on the equator does not actually spin relative to the earth's axis. The paddle wheel located on the north pole however, spins counterclockwise as the earth rotates around its axis. If the paddle wheel at the north pole were moved southward to 60°N, it would still spin as the

earth rotates, but not nearly as fast. If we moved it southward again to 30°N, it would spin even more slowly than it did at 60°N. Finally, at the equator, the paddle wheel would not spin at all relative to the earth's rotation. This is known as the Coriolis Parameter. At different latitudes, it affects the apparent motion of the air flowing over the earth's surface. The Coriolis Parameter also has an effect on high and low pressure systems. We'll look further at high and low pressure areas in Part II of this series. Now back to our cells. The cell originating from the equator is known as the Hadley cell. Warm air rises at the equator and heads north. As this air gets colder and denser, it descends at about 30°N. This cold, dense air creates high pressure at the surface while pressures at the equator are generally lower. At 30°N, we find the subtropical high while the equator is generally referred to as the equatorial low. The polar cell up on top of the earth has the same type of circulation. Warmer air at 60°N rises and heads north. As this air becomes colder and denser, it descends to the surface at the north pole creating a semi-permanent high pressure region. This air then pushes southward along the surface to replace the rising air at 60°N. This area is referred to as the polar low. The middle cell, called the Ferrell cell, is less well-defined than our other two cells, but can be observed statistically. The circulation within this cell travels in an opposite direction than our other two cells, as shown in Figure 13. The curving vertical lines in the center of our triple cell illustrate the Coriolis force on each of the three cells. Surface winds from the equator to 30°N are generally deflected toward the southwest. These are called the

northwest tradewinds. They received their designation from the early sailing ships conducting trade within that region. Surface winds from 30°N to 60°N are generally westerly. Aside from surface heating over land masses during the day which change local wind directions, we can note that weather systems over the continental U.S. flow from west to east. Surface winds in the polar regions are also easterly as the polar cell flow is the same as the Hadley cell. Santa uses these winds to fly his reindeerpropelled glider southward during Christmas. Be sure to note the similarities between the curving lines in the middle of our illustration in relation to their corresponding cell. One last feature among our cells is the jet streams. There are two jet streams in the northern hemisphere. As shown in Figure B, the subtropical jet originates at the top of the descending portion of the Hadley cell. It ranges in altitude between 50,000 feet and 60,000 feet. The polar jet is located around 60°N but does wander in latitude considerably. It is much stronger in speed and much lower in altitude. In the winter, it is not uncommon to find the polar jet sweeping across the U.S. with speeds of over 150 mph at 30,000 feet. The polar jet also contains smaller pockets of extremely highspeed air called jet maxima. We'll learn more about the jet stream and the role it plays in shaping our soaring weather in Part III of this series. A total view of our atmospheric layers will complete this section on global circulation. First, we have the troposphere which is our closest layer to the surface. 80-90% of all weather occurs here. The thickness is greatest at the equator where warm, buoyant air rises, and least at the poles where cold, dense air descends. At the

equator, the troposphere reaches up to 12 miles while at the poles its top is about 4 miles (see Figure C). Temperatures in the troposphere decrease with height on the average. Next, a small, thin layer called the tropopause lies between the troposphere and the next higher layer. The tropopause acts as a lid or cap on the troposphere. As the troposphere descends in altitude over the poles, so does the tropopause. The tropopause however, has the unusual characteristics of "breaks" where there is a dramatic change in altitude of the layer (see Figure D). It is within these breaks that we often find the jet streams. The next layer is the stratosphere. The stratosphere is between 26 to 29 miles thick. JANUARY 1981

feet

There is no temperature change with altitude in the lower regions. In the upper regions however, the temperature increases with height. This is a very stable layer which keeps most towering cumulus development below. While most commercial jetliners travel in the troposphere near the tropopause, the French built SST Super Sonic Transport operates within the stratosphere. A lot of controversy about permanent damage to the environment from operating such aircraft in the stratosphere has kept scheduled flights of the SST out of the USA. Above the stratophere is another thin layer called the stratopause. It too acts as a lid or cap on the stratosphere. Next we have the mesosphere which is about 19 to 22 miles thick. Here, tern-

perature decreases with height much like the troposphere. Gravity affects the atmosphere up to the top of the mesosphere. Above this layer is the ionosphere where electromagnetic forces from the earth's poles prevail. Within the ionosphere, the temperature increases with height very rapidly. At the top of the ionosphere, the temperature is over 2,200°F. Twenty-four hours after solar flares occur on the sun, positive and negative charges in the ionosphere disrupt radio communications here on the surface. The magnetosphere is the last layer above the earth. The magnetosphere is responsible for the northern lights or the Aurora displays after solar eruptions on the sun. The earth's magnetic field (magnetosphere) is directly caused by the interplay of fluid motions and electric currents in the liquid core of the earth. The magnetosphere and the ionosphere are sometimes termed together as the thermosphere. All of these layers combined make up our atmosphere. Although upper atmospheric layers may not have a direct influence on our great sport of hang gliding, your basic understanding of what is up there will give you greater insight into atmospheric changes that occur down below. Part II of this five-part series will offer some valuable insight into the flow of high and low pressure systems. Once you have understood the material in this series on general meteorology, you won't have to rely on the wizards and dragons to tell you what the air is up to. And even Galileo will once again rest in ~ peace.
