-- front / symmetrical tuck collapse
A front tuck / collapse is a symmetric tuck of the leading edge of the wing, starting from
the centre of the canopy to the wing tip. This can be either a tucking of just the central
part of the leading edge of the glider, which can sometimes cause a front 'horseshoe' or
'rosette-ing' of the glider, or even a complete 'front tuck' of the whole canopy in extreme
situations.
When flying, a front tuck may occur
either when leaving a strong ther-
mal, or more often while using the
speed system in turbulent air, or
even sometimes whilst flying into
the wake turbulence down-wind of
another glider.
Remember, the pilot can learn to
help stop collapses by flying 'active-
ly', but if a front tuck does occur it
will easily clear itself. Re-inflating
the wing can be helped by correct
pilot input and, once the glider is
overhead, symmetrically applying
40% of both brakes
& then releasing
immediately will get pressure back
in to the glider and speed up the
recovery. Do not brake when the
glider is behind you, as this can stall
the wing, but wait for the glider to
come forwards above your head,
then brake.
-- asymmetric stall (spin)
This is a very difficult situation for the pilot to provoke with the tuareg, given its excellent
feedback and very low stall speed, you have to really abuse the controls a lot to manage it.
Even so, a spin can be induced if, for example, the pilot is turning very slowly and tight-
ly in a thermal (near the stall point), and wants to tighten the turn further, for whatever
reason. If the pilot brakes too much on the inside brake, stalling the wing on that side,
the wing may then go into a spin.
Beware in turbulent air, as it is easier to stall, or spin, the wing due to the already a tur-
bulent airflow.
If a spin is entered, return to normal flight by raising both hands to return air speed to
the stalled side of the wing. Be careful, as this may cause the wing to surge and dive for-
