Full Stall:
This is an extreme manoeuvre and there should never be any need to perform one in
normal flight.
Do not take wraps with your brakes before entering a full stall. Keep your hands close to
your body during the stall, and lock them under your harness seat plate if necessary. In a
stable full stall, the canopy will oscillate back and forth. Before releasing the stall, raise your
hands slightly and evenly to fill the glider with air.
If possible, let the brakes up when the glider is in front of you to avoid excessive surge. The
U Prime will surge forwards to regain airspeed and you need to counter brake the dive when
the wing surges towards the horizon and then let up the brakes to regain the complete
airspeed of the wing again. Be careful to not stall the glider again when damping the surge.
ATTENTION: IF A FULL STALL IS RELEASED TOO EARLY, TOO SLOW OR TOO FAST,
OR OTHERWISE INCORRECTLY, THE CANOPY CAN SURGE EXTREMELY FAR
FORWARD.
An ”asymmetric” recovery (one control released faster than the other) from a
full stall can cause a big dynamic collapse.
Negative spin:
During a spin the canopy turns relatively fast around the centre section of the canopy while
the inner wing flies backwards (hence the term negative).
There are two usual reasons for an unintentional spin:
- one brake line is being pulled down too far and too fast (e.g. when inducing a
spiral dive)
- when flying at low speed one side is being braked too hard (e.g. when
thermalling).
To recover from an unintentional spin, the pulled down brake line should be immediately
released as soon as a spin is suspected. The canopy will accelerate and return to its normal
straight and stable flying position, without losing too much height.
In case the spin is allowed to develop for some time, the U Prime surges far forward on one
side and a dynamic asymmetric collapse or a line over can occur. If so, brake gently to stop
canopy surging and correct any collapse: See ”collapses”.
Too tight cross bracing increases the probability of a spin with most paragliders!
