there is no stanard spin recovery as there are differences in the recoveries of most aircraft. Some subtle, some large. The recovery technique on one may not work for another - or may even prevent recovery.
I do not agree that this statement applies to civil aircraft in general use. It is, and has been for quite a long time, a design requirement that for any of the "western" civil types which are common to general aviation (in part):
It shall not be possible to obtain uncontrollable spins by means of any possible use of the controls.
And, more recently (in part):
It must be impossible to obtain unrecoverable spins with any use of the flight or engine power controls either at the entry into or during the spin
So, I am unwilling to believe that new pilots cannot be safely taught the basics of spin recognition and recovery.
If they cannot, why not? We were....
