Deep/Parachutal Stall; Cravates - Nova IBEX 2 Manual

Deep/Parachutal stall

The Deep Stall, or Parachutal Stall is kind of the pre stage to a Full Stall. The
wing has no forward motion and a high sink speed, but it is almost fully
inflated. The pilot can enter the Deep Stall by applying both brakes. It is very
difficult to keep the wing in a Deep Stall: If you pull the brakes a little too
much, the glider will enter a Full Stall. If you release the brakes too much, the
glider will go back to normal flight. To practice a Deep Stall, it is necessary to
master the Full Stall first.
A very old or worn out glider with a porous cloth or with a changed trim (due
to many winch launches, or deep spirals) might stay in a deep stall even after
releasing both brakes. Do not apply the brakes in such a situation, because the
wing would then enter a full stall ! You can exit the deep stall by pushing the
speed bar, or by simply pushing the A-risers forward. If you fly through rain,
the risk of a deep stall is higher. We strongly advice against flying in rainy
conditions. If it happens, that you get into rainfall, we recommend not
performing a B-stall or Big Ears. Our recommendation is to leave the rain as
soon as possible and to fly with both brakes released, or even accelerated, as
this reduces the risk of a deep stall.

Cravates

After a big collapse or after a badly executed Full Stall, a part of the wing
might be tangled up in the lines, and won't reopen automatically. This is what
you call a cravate. During our extensive test flights with the IBEX 2 we never
experienced a cravate but this situation can not be eliminated with any
paraglider.
In case of a cravate we recommend the following actions:
1.) Counter steer: Probably the wing wants to turn to the side of the
cravate. In some cases, the turning happens quickly and will end in a
stable deep spiral without the pilot's action. So it is important to react
quickly by counter steering.
2.) Opening the cravate by applying the brake with an impulse movement:
Some cravats can be opened with this method. It is important to keep
the wing in straight flight by pulling the other brake all the time.
