Default ASW-20 spins

Not a glider but, as the T-33a transitioned from a tail slide to an end
over end tumble, I applied the Dash One out of control procedu

Throttle - Idle Ailerons and Rudder - Neutral Stick - Full Aft

The aircraft shook and shuddered and transitioned into an inverted spin.
The flight manual made no distinction between upright and inverted
spins so I continued the above procedure into the spin recovery
procedu

Rudder - Opposite spin direction (look at the slip ball, not the trees,
and keep the rudder against the spin)

The aircraft transitioned into an erect spin (this I could handle!)

Stick - Forward and neutralize rudder when the spin stops and recover
from the dive. Watch out for that nasty secondary stall, the trees are
getting closer!

It's all about applying the correct controls for the situation and
feeling the aircraft. Each aircraft has its quirks. If you're
adventurous you should learn yours unless your flight manual prohibits
such maneuvers. My LS-6 would roll over the top in a final turn stall,
my LAK-17a is much more benign.


Its interesting that nobody has mentioned what it said in the handbook
for my ASW-20A: First action is to push flaps fully negative, then take
normal spin recovery action (stick central, full opposite rudder), adding
that the spin will very often stop when the flaps go negative.

That is exactly what mine did. I haven't forgotten that instruction,
though its 11 years since I last flew an ASW-20. I suspect a good reason
for this instruction is that pushing the flaps has two immediate
benefits:

(1) it will help unstall the wing, which is why that, by itself
can be enough to recover from the spin.

(2) it sets VNE as high as possible, which never hurts where a
steep dive is involved.
