If you are an instructor, in power, what type do you use for teaching? what altitude? Do you let the student put it in the stall and recover, then in the spin and recover, or do you deprive him of that valuable experience?
Once the exercise has been demonstrated it is time for the student to practise, there is no better way of letting them enter the manoeuvre and use the correct recovery technique, better still if they mess it up and have to sort out the problem for themselves that way they are less likely to forget.
I have seen so many instructors hovering over the controls or worse touching/applying inputs to the controls while the student is practising probably because they are not confident in their own ability to recover from a situation.
