The 2 methods are being taught on FIC's.
BEagles method was explained to me to be the RAF's method of teaching which is basically unload the plane and the stall shall disappear. Which dates all the way back to the guy that found out that you cure a stall by pushing forward instead of pulling back which was the method before he discovered this fact. I seem to remember he got court martialled for not pulling back,but hey at least he was alive to be court martialled. It works for all types of stall be it low speed, high speed in the turn etc.
The other method of picking the wing up with yaw is also taught along with some more unusual "unusual attitude recovery techniques" which the yanks are all in favour of. I believe it was a factor in the fin coming off the airbus which was caught in wake turb just after sept 11th.
So the method being taught is mainly due to the background of the instructor. If they have any mil training behind them they will unload. US training they will pick the wing up. And home grown will depend on who trained them for there PPL / FIC.
Most staff examiners are ex mil so they will accept both.
Who's right? who cares the full stall is one of the most artifical exercises in the PPL with some examiners making the students hold it in the full stall for 15-20 seconds or until a wing drops and others letting them recover on the buffet.
Until the chief examiner actually expresses an opinion and publishes it. Both methods will be instructed.
Myself personally had to teach the pick the wing up method because thats what the local examiners wanted. So until the examiners get there act together and stick to the party line there is not alot the instructors can do about it.
Its a bit like the instructors who teach point and push instead of power for sink and attitude for speed in light aircraft.
