DYNAMIC / FULL STALL
If you pulled the brakes further down whilst parachuting, the canopy would tilt backwards while
deflating at the same time. This is what you take advantage of when landing: The canopy is stalled
dynamically - stall and ground contact occur synchronously. In every other situation the full stall is
an unpredictable and dangerous flight configuration, which should not be flown intentionally.
Since the GREEN provides very long brake distances up to the full stall point, an unintentional
dynamic stall can be excluded mostly.
Caution: Never release brakes out of the backward tilt at the beginning of the full stall! You run
the risk of the canopy accelerating below yourself which would result in contact with the canopy
or even falling into the canopy.
In the stalled condition, the GREEN performs a strong flapping movement with the outer wings.
The effect of this movement is transferred to the pilot via the brakes. Safe recovery is performed
smoothly and with medium speed out of a forward movement of the canopy. Here, the brakes must
be released fully, in order to allow the glider to regain speed. In rare cases a frontal or asymmetric
deflation can occur (see above).
SPIN
A stall occurring at one side of the canopy leads to a spinning motion (spin, negative turn). In a spin
the axis of rotation lies within the canopy and the glider turns in the horizontal plane.
You fall into a spin when the brakes are pulled too abruptly out of trim speed as well as out of
slowed speed. This transition from normal turn to spinning is relatively smooth with the GREEN.
By releasing the brake on the inside of the turn you will regain laminar flow and the GREEN contin-
ues with the positive rotation. Both brakes should be released out of a full spin so that the glider
catches up speed. Caution: A spin is a dangerous, unpredictable flight manoeuvre and should not
be flown intentionally! Should the case arise that out of a spin or stall movement a line-entangle-
ment or a tangled outside wing emerge, the resulting rotational movement must be stopped by
counter-steering immediately. The steering force required for this may be considerably higher
than usual! (see above: Collapse with entanglement). Visual reference with the surface must be
maintained at all times and in case of doubt or when losing control, the safety parachute must be
deployed right away!
