Extreme flight maneuvres 45
PARACHUTAL STALL
Deep stall can occur after heavy use due to porous material (UV radiation)
and in the rain (absorption of moisture). The parakite does not accelerate and
gets a high rate of descent.
The FLARE FLARE MOUSTACHE will recover from a parachutal stall by re-
leasing the brakes to ‘full speed’ position immediately.
IF YOU APPLY THE BRAKES DURING A PARACHUTAL STALL, THE
GLIDER WILL IMMEDIATELY ENTER A FULL STALL. NEAR THE
GROUND, A STABLE PARACHUTAL STALL SHOULD NOT BE
EXITED DUE TO THE RESULTING OSCILLATIONS. INSTEAD, THE
PILOT SHOULD SIT UP IN HIS HARNESS AND PREPARE FOR A
PARACHUTE LANDING FALL..
NEGATIVE SPIN
A parakite enters a negative spin when one side of the wing is stalled.
The canopy rotates around the vertical axis with the center of rotation locat-
ed within the wingspan. The inside wing flies backwards.
There are two causes for the negative spin:
> One brake is pulled too far and too hard (e.g. when entering a spiral dive)
> One brake is pulled too hard when flying slowly.
If an accidental negative spin is exited immediately, the FLARE MOUSTACHE
will usually resume flight without much altitude loss. Just release the brake
line pulled too far until the airflow is restored to the inside wing.
After a long negative spin, the canopy may surge forward on one side.
This could result in an impulsive collapse.
WINGOVERS
Alternating left and right turns as the bank angle is gradually increased.
If wingovers are flown high with a large bank angle, the outside wing tip may
loose pressure and start to feel light. In this case, don’t increase the bank an-
gle any more as the tip could collapse impulsively.
NEGATIVE SPINS AND WINGOVERS OVER 90° ARE FORBIDDEN
ACROBATIC MANEUVERS ARE NOT ALLOWED TO BE FLOWN
UNDER NORMAL CONDITIONS IN GERMANY. THE WRONG EXIT
TECHNIQUE OR PILOT OVERREACTION CAN HAVE DANGEROUS
CONSEQUENCES REGARDLESS THE GLIDER TYPE OR PARAKITE!
