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 ARGON 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.
In close proximity to the ground, due to the forward surging pendulum
effect, a recovery may be more dangerous than a hard landing in
parachutal. If landing in a parachutal stall, the pilot should prepare for a
hard landing and make a parachute roll landing.
Full stall:
To induce a full stall, apply full brake on both sides.
The glider slows down steadily until it stalls completely. The canopy
suddenly surges backwards a long way. In spite of this uncomfortable
reaction of the canopy, both brake lines must be consequently held down
with all your strength until the canopy is stabilized (directly overhead).
The NOVA ARGON generally flies backwards during a full stall but
doesn’t always form a front rosette.
A frontal rosette can be formed by entering the full stall slowly. When
entering (braking) fast, the canopy will not always form the desired front
rosette.
ALWAYS APPLY BOTH BRAKES EVENLY!
To recover from a full stall, both brakes must be let up symmetrically at a
fast to moderate speed (within 1 second).
The NOVA ARGON surges forward a moderate amount after recovering
from a full stall, whereby a resulting front collapse is possible. Gentle
symmetrical braking will avoid too strong a forward surge.
