history of paramotors
By
Kurt Kleiner
No one is exactly sure who
invented the sport of paragliding.
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 judgement. 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.
