more risk there is of it getting out of control.
As the glider surges forward, slow it down with the brakes to avoid the possibility of an
asymmetric collapse. Always wait for the glider to be in front of you or above you when
releasing a fully deployed spin - never release the spin while the wing is behind you, because
the glider would dive very far in front of you or even underneath.
m. Full-Stall
This is an extreme manoeuvre that should rarely, if ever, be required.
To induce a full stall, pull both brake-lines down smoothly. Hold them down, locking your arms
under your seat until the canopy falls behind you and deforms into a characteristic crescent
shape. In spite of how uncomfortable it may feel as the glider falls backwards, be careful not to
release the brakes prematurely or asymmetrically. If the brakes are released while the glider is
falling backwards, the surge and dive forwards is very fast and the glider may shoot in front
and even underneath you.
In a full stall the canopy will oscillate back and forth. To stabilize this, you can release the
brakes slowly and for approximately 1/3 of the brake travel and then hold at this level. Holding
at this position allows the wing to refill slightly across the span. When releasing the brakes
without pre-filling, the ears will most probably hook in the lines, and this can result in a cravat.
After pre-filling, the glider stabilizes its movements and the brakes can be leased until the
glider recovers speed and flies again.
NOTE:
The RISE3 has got long brake travel and it demands a deep pull to enter a full stall. If the glider
is stalled very deeply
– means with even more pull on the brakes – the wing will become very
unsteady, resulting in diving strongly back and front. The Pilot should not try to react on the
strong dives back and front but should slowly reduce the brake pull and hold the brakes
symmetrically till the glider relaxes.
ATTENTION: The full stall requires a lot of height and demands certain skills to recover. It is
important this manoeuvre is not practiced without qualified supervision.
It should preferably be practiced during a safety training course.
The
available brake travel before stalling the wing depends on the size and the loading. For the
RISE3 M and L it is a minimum of 65cm (S minimum at 60cm, XS and XXS minimum at 55cm).
Those numbers are just a rough indication. (The publication of the brake travel is claimed by
the EN 926-2.)
It would be dangerous to use the brake travel according to those numbers, because it is not
practicable to measure the brake travel during flight, and in turbulences the stall might occur
with less brake travel. If you want to use the whole brake travel of your glider safely, it is
necessary to do intended spins and full stalls to get a feeling for the stall behaviour
–
preferable during a safety training course.
NOTE:
IN GENERAL THE BRAKE TRAVEL BECOMES SHORTER DURING A SIDE COLLAPSE (WHEN TRYING
TO STABILIZE ON THE OPEN SIDE)!
