Asymmetric Collapse; Symmetric Collapse; Deep Stall - Axis VEGA II Pilot's Manual

Recovery: The Vega II recovers from a spiral spontaneously as soon as the brakes are
released and weight shift returns to neutral. To exit allow the spiral to slow for a turn
or two by applying outer brake and weight shift then release smoothly. Always finish a
spiral dive at a safe altitude.
C. Flying in turbulent conditions
Deflations can occur when flying in turbulence but in most situations the Vega II will
stabilise without pilot input. Flying with a little brake applied equally will help to
prevent deflations and allow you to experience more direct feedback.
Active flying will help avoid deflations. The aim is to keep the glider above your head
in all situations by responding correctly to the glider's movements by using the brakes
and weight shift.
It is important these manoeuvres are initially practiced under qualified supervision and
preferably during a safety training course.

Asymmetric collapse

The Vega II will normally re-inflate after an asymmetric collapse without input from the
pilot, but the wing will turn towards the collapsed side. You should always maintain
course and direction by weight-shifting away from the collapsed side. This can be
reinforced by applying a small amount of brake on the opposite side to the deflation. If
the collapse stays in, the collapsed side can be re-inflated by pumping the brake on
the collapsed side in a firm and smooth manner.
If you experience a big collapse while accelerated the canopy will fall behind you due
to the difference in inertia between you and the canopy. You must wait until you
pendulum back under the canopy before dealing with the deflation. Reacting too early
can risk stalling the glider completely. Release the speed-bar immediately if you have a
big collapse during accelerated flight and, while keeping weightshift neutral, apply
slight brake to the open side. Let the glider enter a turn if space allows in order to
avoid a spin or stall.

Symmetric collapse

A symmetric, or frontal, collapse will normally reopen without any pilot input. The
Vega II will regain airspeed with a small surge. Be careful not to brake while the glider
is behind you as this could induce a stall.

Deep stall

The Vega II has no tendency to either get into, or stay in, a deep stall. If the glider does
enter a deep stall, accelerate the glider out of the deep stall by either pushing on the
A-risers or by using the speed bar. Never try to steer out of a deep stall. A wet glider
