NOTE: We recommend supporting the reopening after a frontal deflation by pulling the brakes.
k. Reopening a Cravat
In extreme conditions and rare cases it is possible that the wing tip(s) can become trapped
between the lines. In general, this would happen only after a big uncontrolled collapse or
during extreme manoeuvres.
If this cravat occurs, in the first instance use the techniques described for releasing asymmetric
collapses.
If it fails to release, take hold of the stabilo-line (green coloured line) and pull constantly
towards yourself until the trapped section of the wing is released. Another method would be
to stall the wing (see at m. Full-stall)
At low altitude it is important to stabilize the rotation, if any, and if this is not possible use the
reserve (rescue).
l. Negative Spin
We recommend that this manoeuvre is only carried out during a safety training course over
water and under supervision. The intention in this situation is for a pilot to discover the point-
of-spin and to control it. This demands a high level of experience and skill.
The longer the time between the glider entering a spin and the pilot attempting to recover, the
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.
The
available brake travel before stalling the wing depends on the size and the loading. For the
VOLT2 M it is a minimum of 50cm. 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
