Hello
the pilot needs only to let go of the controls and the plane will fly itself out of the stall
Very bad training philosophy, imho.
If you teach stall recovery, teach it in realistic conditions.
In conditions less than ideal, in a context that includes some equipment malfunctions and/or pilots mistakes : those are the usual pre-conditions of a real accidental stall ...
If you demonstrate approach to stall recovery in "ideal" conditions, where is the interest? In ideal conditions, you won't approach stall ...
Instead, go as deep as possible into realistic teaching ... A simulator crash is not a drama ...
A light airplane is a good teaching tool too :
I can demonstrate trim upset in a C182 ... with different recovery options
And accidental
vicious spin entry as well. I garantee that!
