Too late, it don't take long to turn in to a full spin from an incipient spin.
Exactly the reason why the CAA shouldn't be requiring FI revalidations to include the demonstration of incipient spins in aeroplanes with 'intentional spinning is prohibited' in their POH.
421dog, you clearly have no idea of RAF Bulldog spinning instruction. The reason why we did so much was that the aircraft was flown to its limits and students had to be adequately competent at both spinning and recoveries from the vertical before being cleared to fly aerobatics solo. Whereas the average PPL holder has neither need nor wish to get anywhere close to any such limits and needs more to be taught how to recognise and recover from getting anywhere close to an incipient spin.
Lightning6, 'spin recovery' training in the Cessna 150 and PA28 Cherokee 140 was a nonsense. The C150 was better, but both required what was basically a low speed flick entry to depart from controlled flight. The most difficult part in the PA28 was recovering without overspeeding the engine and/or overstressing. Totally pointless - who is ever going to pull the control column fully aft and apply full rudder other than deliberately?
However, mishandle a T67A at the stall (particularly a dynamic stall) and it would easily enter an incipient spin.... Lousy aeroplane for most aerobatics, but very good indeed for stall / spin training.
