This is a first !!............ I find myself agreeing with Bose-X
Ditto !!!
I don't see much value in it until after someone is an accomplished pilot and can actually enjoy it and do it as part of exploring the envelope of the aeroplane.
Why? Well how many Twin pilots were taught to spin a Twin? How many Boeing drivers are taught spin recovery in a Boeing? None!! You could argue that you are more likely to spin a twin, with asymetric power and all that, but other than experiencing Vmc you never go near a spin....And why should you, the idea is not to spin!
Anyway with *most* single engine low performance aeroplanes there is one fool proof recovery technique, given enough height. Throttle closed and let go of everything.....
