C-Stall; Collapses; Asymmetric Collapse - Nova Prion Manual

The pilot will feel the entering of this phase by the suddenly increased g-force.
In this moment, the pilot is being pushed to the outer side of the harness. It is
important to not counteract. So the pilot should lean to the outer side to avoid a
stable spiral. (See below)
If the pilot weight shifts to the outer side, the spiral movement will get slower
as soon as the pilot releases the inner brake. The rest of the exit works as
explained above for the first phase of the deep spiral.
If the pilot shifts his weight extremely to the inner side, the PRION might stay
in a deep spiral, even when releasing both brakes. In this case, it helps to apply
the outer brake, or both brakes and of course to shift the weight to the outer
side.
Please don't underestimate the difficulty of learning the deep spiral. The sink
rates are a lot higher than what you are used to from other manoeuvres and the
fast rotation might lead to disorientation. The high g-loads of up to 3g make the
manoeuvre even more demanding as you might have problems like the so
called "black out", where you temporarily lose your vision due to the g-load. It
is very important to get a feeling for the reactions of your body to this
manoeuvre.
If you practice it well, it is a fun manoeuvre that enables you to loose height
faster than with any other manoeuvre.

C-Stall

This manoeuvre can be found sporadically in some paragliding literature. We
don't recommend it, because entering and exiting the C-stall can be very
demanding and dangerous for many pilots.

Collapses

Asymmetric collapse

If you fly in strong turbulences, one side of the glider might collapse. This
happens if one side of the wing doesn't produce lift anymore, due to a low
angle of attack. If there is no lift, the lines get loose and the wing deforms or
collapses.
