EXTREME FLYING MANOEUVRES
inflated side to stop the turning movement of the canopy will help the canopy regain
proper flight. If you react immediately with 30% brake on, the open side should 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 maintaining direction can be aided by 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 pilot does not take corrective action the canopy can enter a stable spiral
dive.
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.
“Cravat” / Line-over:
In the event of some lines becoming tangled during flight (caused by whatever), the
following action is recommended:
Stabilize the glider by gently applying the opposite brake. Please be aware that in this
condition the brake pressure can be higher and the brake travel shorter.
Without pilot input, a line-over will result in a stable spiral dive.
Here are the various options to untangle a line-over:
- pumping the collapsed side.
- pulling the stabilizer line or a sharp pull on the D riser can sometimes solve the
problem.
Attention! If these manoeuvres fail or if in any doubt, the pilot should instantly use their
emergency reserve parachute system!
Frontal Collapse:
Frontal collapses provoked at higher speeds can lead to extremely deep collapses.
Recovery requires short and equal application of both brakes.
When experiencing a very large front tuck, a frontal rosette can occur (the wingtips
move forwards: forming a horseshoe shape). Short and gentle braking can avoid this.
A quick recognition of the situation and a quick reaction by braking on both sides for as
long as the collapsed wing is behind the pilot helps the recovery and limits the altitude
loss.
Parachutal stall (deep stall):
A parachutal stall can be caused by having the glider fly too slowly. The most
common cause is from pulling too much brake, however, porous canopies (UV
influence) or canopies out of trim (stretched or shrunken lines) are much
moresusceptible to a parachutal stall. Gliders in poor condition should not be
flown. This is the reason why regular checks should be carried out on your glider.
A wet canopy or temperatures below zero centigrade (0°C) may also cause a
stable parachutal stall.
