An odd concept... I'm therefore curious to know what your instructor or examiner pulled on you - any ideas?
Not sure what you mean by 'give back'.
I can only say what happened on my course, last year. You are required to demonstrate recovery from a spin during your test, but not to teach it, so...
Whenever we had the opportunity to climb to 4,000' during the course, we'd do so at the end of a particular session and practice spin entry and recovery. I did patter through what I was doing, but I'm not sure if this is strictly necessary on the test, providing the recovery is clearly demonstrated. Personally, I think it is better to talk through what you're doing so that if it is less than perfect, then the examiner will at least understand what you were trying to achieve. I did my course and test on C152s. Entry was: wings level, reduce power to 1500 RPM, gradually raise the nose, keeping in balance and level flight, smoothly and progressively pull back on the controls until the aircraft stalls, apply full left rudder. Aircraft enters an autorotative condition to the left (stand back for plenty of arguments from people saying 'this isn't a proper spin' - just ignore them!). Close throttle and ensure ailerons centralised. After 2 turns - count them out loud - apply opposite rudder and centralise elevator. Spin should stop promptly. Recover from ensuing dive as for stall recovery. Make sure that you follow proper POH instructions for the type you're flying.
There'll be many arguments I'm sure about the rights and wrongs of the above. Hope it isn't as many pages as the thread about log book entries!
