14.8 Flat spin
A one sided stall leads to spinning (one-sided negative turns). Here the centre of rotation
is inside the glider’s canopy and the glider hardly has any banking. Spins occur if, due to
trim speed and braked flight, the brakes are pulled on too abruptly. With the Green b
the transfer from normal turns to a spin is very smooth. By easing off the inner brake line
the flow is reintroduced and the Green b continues on a positive turn. Both brakes
should be completely released from a full spin so that the glider can pick up speed again.
Caution: Spinning is a dangerous flying manoeuvre that cannot be calculated and should
not be intentionally undertaken! If a line cross or tangled outer wing occur due to a spin
or stall movement, the resulting rotational movement must immediately be stopped by
counter steering.
The steering power needed for this can be considerably higher than normal! (See above
collapse with tangles.) You should always observe the height above ground and if in doubt
or in cases of a loss of control immediately deploy the rescue equipment!
14.9 Brake failure
The brake handle must always be attached to the brake line with a suitable knot (see
chapter on adjustment options)! If this is not ensured or if the brake line is damaged then
this can lead to a loss of braking. The same thing can occur if the brake handle has be-
come knotted in the brake pulley.
In these situations you should remain calm. The Green b can be steered adequately
even without using the brakes. The C-main lines on the affected side can be pulled down.
As the stall will therefore occur somewhat earlier, no strenuous manoeuvres should be
attempted.
