Line Over; Front Stall; Parachutal Stall (Deep Stall) - Nova PRIMAX Betriebshandbuch

43
If the pilot does not correct, the NOVA PRIMAX usually self-recovers. However, if
it does not self recover and the pilot does not correct the canopy can enter a
stable spiral dive.

Line over:

The pilot stabilizes the glider by gently applying the brakes. Without the pilot's
action the line over will result in a stable spiral dive.
Here are various possibilities to untangle a line over:
- pumping the collapsed side.
- pulling the stabilizer line or lines causing problem.
- should both measures fail, it is possible to untangle the line over by inducing
a full stall. This manoeuvre, however, should only be carried out by advanced
pilots with experience in extreme flight situations and with sufficient altitude
available.
IF THESE MANOEUVRES FAIL OR IF IN ANY DOUBT, THE PILOT SHOULD
INSTANTLY USE THE RESCUE SYSTEM!

Front stall:

A front stall can be induced by strongly pulling the A-risers or by sudden, heavy
turbulence. The entire leading edge impulsively collapses.
Gentle braking on both sides will reduce the lateral pendulum motions and
simultaneously accelerate reinflation. The NOVA PRIMAX generally self recov-
ers from an initiated front stall.
When having a very big frontstall, a front rosette can happen (wingtips are
moving forwards: the wing is shaping a horse shoe). Gentle braking can avoid
this deformation.

Parachutal Stall (deep stall):

The paraglider has no forward momentum combined with a high descent rate.
A parachutal stall is caused, among other reasons, by a too slowly exited B-
stall or severe turbulence.
Porous canopies or canopies out of trim (stretched or shrunken lines) are
much more susceptible to a parachutal stall and therefore should not be
flown. These are some of the reasons regular checks should be carried out
on your glider.
The NOVA PRIMAX generally is self recovering from parachutal stall. If the
canopy remains in a parachutal stall, it is sufficient to gently push both A risers
forward or to push the accelerator.
