Reopening a cravat
In extreme conditions 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 and pull hard towards the pilot until the
trapped section of the wing is released.
A full-stall should be the last option to reopen a cravat and is a manoeuvre for experienced
pilots only and should be attempted only if there is sufficient altitude. At low altitude it is
important to stabilise the rotation, if any, and if necessary use the reserve (rescue) if this is not
possible.
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.
However, if a spin occurs the RISE is capable of recovering automatically when the brakes are
released quickly and equally. The longer the time between the glider entering a spin and the
pilot attempting to recover, the more chance there is of it becoming 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 - never brake
while it is behind you as this can risk a stall.
m.
Full-stall
This is an extreme manoeuvre that should rarely, if ever, be required.
To induce a full stall take one or two wraps of the brake lines and pull both of them 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 the pilot.
In a full stall the canopy will oscillate back and forth. To stabilise this, the pilot 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.
The RISE recovers from a full stall automatically after the brakes are released.
During correct recovery from a stable full stall, the RISE shows no tendency to surge strongly in
front of the pilot.
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 be preferably being practiced during a safety training course.
