whatunion, do you find English difficult....
1. The reasons for tip stall:
Cl v AoA curve and actual AoA at each part of the wing. Exacerbated by poor rigging, power effects and flap angle (eta tab)
2. The difference between design requirements for stalling behaviour and the standard stall recovery techniques for a stall with wing drop....
One is an airframe design requirement, the other is a technique.
Given your "35 yeras of profesional flying" (sic), please explain what on earth 'falling out of the bottom of a loop' means? In 35 years of professional flying I have never come across this phenomenon before. Others have also asked you to expound on this, but all we've heard so far is a deafening silence.
Earlier you stated:
".....for anybody who is not convinced can i suggest you stall and spin a cherokee with a front seat passenger and then try it with 4 heavy male passengers on board (but dont do it until i give you the recovery technique in my next post)"
You do know what the spinning limits on the PA28 are, I suppose?
