I was taught Chop(power), Prop(full), Drop(nose down), Gear (at gear speed),
Flaps (initial, then full when in white arc), 60 degree bank away from the
fire, holding airspeed at the top of the white arc. It would get you down
fast, add rudder and we'd see over 2500 fpm down. After about 2 turns of
that demonstration, my DE said... Ok, good enough.

Commercial students that I taught this method to needed to be eased into it,
but after one or two attempts, most found it fun.

Thanks Jim.
That gets me to wondering... what about a spin?
A spin will give you a high rate of descent at stall speed.
If the aircraft is not approved for spins, that might lead to an
indecisive moment. Just because it is not approved, does not mean it
will not recover. It just means that it might not have been tested.
