It is not appropriate for a QFI to teach a new student how to fly a TP investigative technique. We need to teach and fully explain how aeroplanes behave and how to operate them in normal service .
3 Point - I don't want to flog a dead horse but I think we might have to agree to disagree here.
My patter is on the lines of "When test pilots are looking at how a new aeroplane stalls they don't like frights so they do it this way (quick demo) which enables them to nibble at the AoA to gently investigate what happens.
However if you (bloggs) should stall by accident then it is likely that you will overshoot to a much higher AoA
because of the rate at which you are approaching the stall therefore you must learn what that is like and learn to cope with it" (demo S&L throttle shut) "Not the same eh?" "Now you have a go....etc etc"
