EXTREME FLYING MANOEUVRES
This section describes flying conditions which can be deliberately induced, or which can
develop unintentionally due to turbulence or pilot error. Any pilot who flies through
turbulence is sure to be faced with these special flight conditions at some point. So take a
good look at these flight manoeuvres or prepare for them by SIV (safety training over
water). Mastering these flying conditions significantly improves your active flight safety.
Sufficient height, as well as carrying a reserve parachute, is imperative.
WARNING!! All the critical flight conditions described here require a thorough knowledge;
otherwise carrying them out may be very dangerous. Sufficient height above the ground is
imperative. Bear in mind that all deformations of the canopy can increase the sink rate by 2
- 10 m/sec, depending on the degree of deformation. Carrying out these manoeuvres
wrongly may lead to a crash.
Remember this is a glider with unspectacular reactions to disturbances in the air.
Whenever in doubt, raise the brakes and let the glider fly. The glider has a high internal
pressure, resistance to tucking and very high degree of passive safety. It is recommended
that at this stage you already practise an active flying style. The key to active piloting is
keeping the glider above your head at all times. We recommend in principle that you hold
the brake handle in your hand whenever possible, or fly with your hands through the brake
handles, to allow you to react immediately to any possible disturbances.
Warning!!! In according to its construction some manoeuvres could not be tested. It
is asymetric and frontal collapses in the combination of accelerator and open
trimmers.
Asymmetric collapse:
A negative angle of attack can cause all or part of the leading-edge of the Eden 5 to
collapse (e.g. in turbulent air). Basically the Eden 5 will re-open spontaneously from
closures of up to 70% with a change of direction of up to 360°. The time this takes, and the
associated height loss, can however be noticeably reduced by appropriate action by the
pilot. Apply opposite brake on the inflated side, the outside of the curve, to stop the turning
movement of the canopy. This should be accompanied by appropriate weight-shift. If you
react immediately, 30% brake on the open side should suffice to hold the canopy on a
straight course. In the event of a big collapse, this braking should be applied very carefully
to avoid stalling the remaining inflated wing. The pilot’s correction for direction can be
aided by a pumping out the deflation; a slow, long pumping action of the brake of the
deflated side of the wing helps the canopy to re-inflate. If the glider does not self recover
and the pilot does not correct the canopy can enter a stable spiral dive!
“Cravat” / Line-over:
In the event of some lines becoming tangled during flight (caused by whatever), the
following action is recommended: The pilot stabilizes the glider by gently applying the
brakes. Please be aware that in this condition the brake pressure can be higher and the
brake travel shorter.
