Front Stall; Parachutal Stall (Deep Stall) - Nova Mentor Betriebshandbuch

- 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 MENTOR generally self re-
covers from an initiated front stall.
When having a very big front stall, a front rosette can happen (wingtips are
moving forwards: the wing is shaping a horse shoe). Gentle braking can avoid
this deformation.
A quick cognition of the situation and a quick reaction by braking on both sides
as long as the collapsed wing is behind the pilot helps to recover and keep the
altitude loss limited.
ATTENTION: IN THE CASE THIS PILOT REACTIONS DON'T SUCCEED, OR
THE PILOT FEELS HIMSELF OVERSTRAINED OR THE ALTITUDE IS TOO
LOW, INSTANTLY USE THE RESCUE SYSTEM!

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 (UV influence) 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.
A whet canopy, or temperatures below zero centigrades (0°C) may as well
cause a stable parachutal stall.
The NOVA MENTOR 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.
WARNING: IF BRAKES ARE APPLIED WHILE IN A PARACHUTAL STALL,
THE GLIDER MAY SUDDENLY ENTER A FULL STALL.
