From
Parachutes to Paragliders

No one is
exactly sure who invented the sport of paragliding, but we think it was
David Barish, Nasa 1963 ?
However, there are photographs and video footage of a group of skydivers
flying their parachutes off of small hills in eastern Montana in the
late seventies. At about this same time, a handful of climbers in the
French Alps began to use ram-air skydiving canopies to make safe and
efficient descents from peaks after ascending technical routes. These
parachutes weighed only eight pounds, flew at 20 mph., and were able to
glide about three feet forward for every foot of altitude lost. By the
mid-eighties, people realized there was a whole new challenge in
prolonging the distance and duration of such flights if one could find
and loiter in areas of rising air like the hang gliders did.
With this challenge came many attempts to improve parachute glide
performance by using non-porous fabric, increasing the wingspan, and
modifying the shape and trim of the airfoil. As each new design was
tested, unexpected changes in the flight characteristics often appeared
which demanded different pilot skills and techniques. Ideas which worked
well were produced in large numbers to meet the demands of a growing
population of paraglider pilots. The sport was well-established in
Europe by 1986.
For several years, a wide range of equipment was developed in the US,
Europe, and Asia. A few gliders with very dangerous flight
characteristics were hastily distributed in the international market
while other manufacturers conducted thorough tests with pilot safety in
mind. In the US, at least three manufacturers of skydiving equipment
were involved in developing and marketing paragliders which were
extremely safe and stable, but which lacked the performance of the
European designs. Since then, all three have returned their attention
exclusively back to the skydiving market, primarily for economic
reasons. By the early nineties, there were fewer radical new designs
emerging, and production was concentrated on paragliders with very
stable handling characteristics for the general flying population.
Distinctions emerged among wings intended for students,
intermediate/recreational pilots, and competition pilots. Standardized
procedures for testing and certifying paragliders were established in
France and Germany which now represent the benchmark for manufacturers
around the world. Today, there are few pilots willing to fly an
uncertified glider, and there are many regulated flying sites where the
French or German certification is required. It is interesting to note
that, although paragliders evolved from ram air skydiving parachute
technology, the two sports have not completely diverged. In fact, they
have begun to come full-circle in some regards. There are presently
several sport jumping canopy designs emerging which have non-porous
fabric, elliptical shaped wings, and thin-profile airfoils which allow
for higher speeds, better glide performance, and greater aerodynamic
efficiency. These features, which were developed for paragliders, are
now being incorporated back into skydiving parachutes. Beware that, even
though paragliders may look similar to some skydiving canopies at first
glance, they have very different flight characteristics which require
completely different pilot technique. Proper instruction is an absolute
must, even for a hang glider pilot or a highly experienced skydiver. A
student paraglider pilot spends hours learning how to ground-handle and
launch a wing in different wind conditions. There is also a variety of
procedures for managing the dynamic changes in flight characteristics
which commonly occur when paragliders are flown in turbulent air.
Understanding what is taking place and practicing the appropriate
response under the direction of an instructor is essential for pilot
safety.
In addition to learning how to launch, land, and control a paraglider in
flight, a student spends considerable time studying meteorology on both
the large and small scale. For example, it is critical to understand the
effect that terrain features have on the movement of air. It is also
important for pilots to know how changes in cloud conditions,
atmospheric stability, and even the time of day can dramatically
influence the outcome and safety of a flight. Considering the complexity
of the weather, it's no wonder that even the most experienced pilots
feel they are in a constant state of learning throughout a lifetime of
soaring.
The most important requirement for safe and successful paragliding is a
proper attitude and good judgment. A pilot flying the most stable
glider on the market, off the safest hill on the planet, and in a calm
wind is not guaranteed a safe flight if concentration is lost, poor
decisions are made, or a complacent attitude prevails. When learning to
fly, listen carefully to your instructor and other pilots. Read what is
recommended and then more. Pay close attention to what you are doing and
double check all your equipment before launch. Spend considerable time
studying the clouds and the wind speed and direction for changes,
trends, and cycles. Watch how these changes affect the flights of other
pilots. Once you are skilled enough to earn a pilot certification and
fly on your own, don't let the learning stop. Review emergency
procedures frequently in your mind and always leave yourself a "way
out" should the conditions of your flight change. Do not be in a
hurry to buy high performance equipment. Allow yourself a couple hundred
hours to experience different conditions and fly at different sites
before complicating your life with equipment that requires more
attention and quicker responses than you can provide as a novice. While
in the air, know where all the other gliders are at all times.
Constantly think and plan ahead. You must be in control of the glider,
not vice versa. Most of all, trust your instincts. Don't fly if
something doesn't feel right. There is much truth to the old saying that
it's better to be on the ground wishing you were in the air than to be
in the air wishing you were on the ground. Respect the weather and what
it can do. Have fun and let's be careful out there.
