Extreme Flying; Deflation And Collapse; Deep Stall; Full Stall - FireBird Z-One DHV 1 Manuel

5. Extreme Flying

It is advisable for all pilots who wish to learn extreme manoeuvres and how to
handle emergencies to attend a safety training course.

5.1 Deflation and Collapse

Due to the flexible shape of a paraglider, turbulence may cause a portion of
the wing to suddenly collapse.
An asymmetrical collapse can be easily controlled by weight shifting to the
open side and applying the minimum amount of brake required to control your
direction.
A long, smooth progressive pump on the deflated side will assist reinflation.
A symmetrical collapse should reinflate quickly without pilot input, however
smooth input of brake applied symmetrically will speed up the process. If a
wing tip remains stuck in the lines, it is recommended to pull the stabiliser line
(the outer B-line).
Active flying will virtually eliminate any tendency to collapse.

5.2 Deep Stall

This paraglider is designed to exit immediately from any deep-stall
configuration within four seconds of the brakes or B-line stall being released. If
you find yourself in a deep stall situation (loss of forward speed, low internal
wing pressure) ensure your brakes are up. If your glider does not return to
normal flight, your should gently push the A-risers forward until the glider
surges slightly and normal flight is resumed.

5.3 Full Stall

Every pilot full stalls their glider during every flight (Flair, coming into land)
however, carrying out a full stall while flying, is a radical and dangerous
manouver and should be avoided at all costs. It is possible to enter a gust stall
during strong thermal conditions; if this happens then the following actions
should be taken:
Keep your brakes applied, don't be tempted to release them. Allow the canopy
to re appear above head then release the brakes smoothly, be prepared to
damp down the surge. A wrong exit from a full stall could lead to further
difficulties, therefore be prepared to deploy reserve.
