Full Stall; Negative Spin - Axis VEGA II Pilot's Manual

has a higher tendency to deep stall, so if you pass through rain accelerate a little and
avoid using big-ears until the glider is dry.

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 a stable full stall the canopy will
oscillate back and forth. Be careful not to release the brakes prematurely or
asymmetrically.
The Vega II recovers from a full stall automatically after the brakes are released. During
correct recovery, where the brakes are let up a little to allow air to enter the glider prior
to being released when the glider is in front of you, the Vega II shows no tendency to
surge strongly in front of the pilot.
If the brakes are released prematurely or too quickly there is a possible tendency for
the glider to surge. This can be corrected by simultaneous equal braking on both sides.
Be careful not to release the brakes asymmetrically as this can cause a large
asymmetric collapse followed by a tendency to enter a spin.

Negative spin

Should a spin occur the Vega II is capable of recovering automatically when the brakes
are released. 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.
Remember: A wrong manoeuvre at the wrong time may change a straightforward
situation into a dangerous problem. Extreme manoeuvres also expose your glider to forces
which may damage it. Practice these techniques under adequate supervision preferably
during a safety training course.
