I have always been an advocate of spin awareness/training. I understand the salient points about PPL training and the possible lack of suitably experienced instructors, however, wherever possible IMO all pilots should at least experience this. The report on another thread currently running, the Canadian Seneca Training accident, makes valued and very sobering reading. Decay of airspeed, in a climbing right turn, pretty vicious wing drop and stall.
BP is of course very accurate that if it happens at low altitude, then options are very limited, we had an entertaing EFATO thread all about that and the turn back manoeuvre at low altitude.
