6. Extreme Flying Manoeuvres
EXTREME FLYING MANOEUVRES SHOULD ONLY BE CARRIED OUT
DURING SAFETY TRAINING COURSE (INSTABILITY TRAINING) UNDER
PROPER INSTRUCTION!
TUCK
A negative angle of attack will cause the Dudek VOX, like any other
paraglider, to tuck.
If one wing tucks, straight flight is maintained by "correcting for direction", by
weight shifting and braking gently on the inflated side. The pilot's "correction
for direction" can be aided by a "pumping out of the deflation", a slow, long
pumping action on the brake of the deflated side of the wing helps the
canopy to re-inflate.
In case of a big tuck more weight shifting should be made and this braking
should be very gentle to avoid the remaining inflated canopy from stalling.
This will result a greater margin of safety from the stall point.
If the pilot does not correct for direction, the canopy usually self-recovers, in
smooth air, in less than 1 complete turn. In case the canopy does not
recover by itself, the appropriate amount of brake must be applied to correct
for direction and exit the turn otherwise the glider will enter a spiral dive.
If this spiral dive is entered, it should be exited by slowly and gently applying
the outside brake until the canopy starts to retain a level bank angle.
Just at this phase, when the pilot pendulums under and in front of the
canopy, it is vital that the brakes are applied very gently, feeling the pressure
and not applying too much. In fact, often it is necessary to partially release
the brakes. When the glider is flying straight and level again, "pump out" the
collapsed side.
IF THE PILOT DOES NOT ACTIVELY EXIT FROM THE ABOVE SPIRAL, IT
WILL CONTINUE UNTIL IMPACT!
FULL STALL
To induce a full stall, apply full brake on both sides and hold the brakes in
that position with all your strength.
Applying the breaks slowly more and more, will also lead the Dudek VOX
into a full stall. In this case however, wing will warn pilot before it enters the
stall point.
At this moment pilot feels a very high resistance on the breaks and wing falls
