An “asymmetric” recovery (one control released faster than the other) from a full
stall is only used by test pilots to simulate a paraglider falling out of a thermal and
must not be practised by pilots.
An asymmetric recovery from a full stall may result in a big, dynamic, tuck.
The danger of overcorrecting and overreacting exists during all extreme flight
manoeuvres: Thus, any corrective action must be gentle and steady and done with
feel !
Spin :
A spin is induced when the pilot in full speed (DHV test) or in very slow flight
(AFNOR) pulls one brake line all the way down very hard and very quickly.
During a spin the canopy turns relatively fast around the centre section of the
canopy while the inner wing flies backwards.
To recover from a unintentional spin, the pulled down brake / control line should be
immediately eased off as soon as the situation is noticed, so that the canopy may
accelerate and return to its normal straight and stable flying position, without losing
too much height.
For recovery from an intentional spin, also release pulled down control line. Watch
for and dampen any surging.
In case the spin is allowed to develop for some time, the SOL KANGAROO surges forward on
one side and a big and dynamic asymmetric tuck can occur. If so brake gently to stop canopy
surging, correcting tuck : see “tucks “.
Wingover :
To induce a wingover the pilot flies consecutive alternating turns to gradually
steepen the angle of bank. Too steep an angle of attack will result in a collapse,
which may be quite dynamic.
Warning:
A turn with more than a 60 degree angle of bank is illegal aerobatics !
Front stall :
If the pilot pulls both A-risers a front stall is induced: the entire leading edge tucks
and the canopy generally forms a frontal horseshoe.
THE SINK RATE FROM THIS MANOEUVRE CAN BE VERY HIGH. ENSURE
YOU HAVE ENOUGH HEIGHT.
