airwave WAVE 2 Manuel D'utilisation page 32

The second method to exit from deep stall is to pull gently on the A risers. This helps the
airflow to re-attach to the leading edge, but care should be taken not to pull down too hard as
this will induce a front collapse.
If the deep stall is particularly stubborn and the previous methods do not work then a full stall
will solve the problem. To do this apply both brakes again fairly quickly, as if to do a strong
stall, then immediately release both brakes and damp out the surge forward in the normal way.
The canopy will collapse behind you then automatically reinflate and surge forward in front of
the pilot before returning to normal flight. It is the surge forward that exits the canopy from
deep stall.
Sp in
This manoeuvre is dangerous and should not be practiced in the course of normal flying.
Spins occur when the pilot tries to turn too fast. In a spin the pilot, lines and canopy basically stay
vertical and rotate around a vertical axis. The WAVE 2 will resist spinning, but if a spin is inadvertently
induced the pilot should release the brake pressure but always be ready to damp out any dive as the
glider exits the spin. If the pilot does not damp the dive on exiting the spin the glider may have an
asymmetric deflation.
Asym etric Front De fl ati on
The WAVE 2 is very resistant to deflations, however if the canopy collapses on one side due to
turbulence, then first of all control the direction of flight by countering on the opposite brake. Most
normal collapses will immediately reinflate on their own and you will hardly have time to react before
the wing reinflates automatically.
However with some more persistent collapses it may be necessary to actually pump the brake on the
collapsed wing. The pumps on the brake should be long, strong, smooth and firm. Normally one or two
pumps of around 80 cm will be sufficient. Each pump should be applied in about one second and
smoothly released. In severe cases it can be more effective to pump both brakes together to get the
canopy to reinflate. Be careful not to stall the wing completely if this technique is used.

It is possible that turbulence can cause the front of the wing to symmetrically collapse, though active
piloting by the pilot can largely stop this manouvre occurring accidentally. The same effect can be
reproduced by the pilot taking hold of both the A risers and pulling down sharply on them. In such a
situation the WAVE 2 will automatically recover on its own in around 3 seconds, during this recovery
period it is not adviseable to apply the brakes as this could stall the wing.

Also controlling the direction will tend to reinflate the wing.
