What is emerging from this thread is a disagreement over the best time in one's training to experience and recognise a spin, and to avoid or correct as needed.
Not until five years after starting to fly could I anticipate the required spins without fear and trembling. Certainly not helped by a macho power instructor who I think wanted to actively discourage my further flying.
I still came back. But got a different instructor.
As a gliding instructor, we introduce a "confidence stall" at the very beginning, in fact, 2 or 3 gentle stalls just to get over the fear of stalling.
(And I like to demonstrate that we stall on EVERY flight, if it is a properly held off landing).
But a fully developed spin is a real freak out for a lot of people. I did make the mistake of using one to descend from 5,000' after a half hour's trial lesson with a very very bold pupil, who actually asked for a spin. He never came back. (During the flight, I asked what he did for a living, he told me he was a bomb disposal expert on a nearby base).
Even experienced pilots still dread the spin, even in the docile K13. I must say overall I agree with the current approach, because even if someone has turned back dangerously after EFATO, and added to the statistics, can this not be better avoided by emphasising correct action of landing ahead?
