Let me add to that. What Mr Church is advocating, the training and awareness, is all good. The ability to be confident in the machine you fly, at high angles of bank, and AOA, is superb. However, the basic PPL/NPPL course, UK, that omits even spin training awareness, leaves the majority of pilots (I would assume), without the basic skills set to look at the turn around procedure that is suggested.
Where he is coming from I would guess, is that this may/should be part of PPL training. The issue with this is that potentially a lot of trainees/instructors may not be comfortable with these manouveres at low altitude. It is different in practise higher up, but at 500-1000 feet it is a different story.
Everyone should try it though. Qualified instructor at their side of course. G - Jon Eckelbars - Flying the Beech Bonanza (ref).
