OK.
I did take time to absorb the meat of the presentation and some of the attached documents. As a light ac pilot I can appreciate there are some differences between stall/spinning a Pitts vs an Airliner.
We can go on about 'how can you fly an aircraft if you don't hit the edges of the envelope a bit' (I think I do every time I fly). I took a 200+ hour pilot up recently for a check flight and he was horrified when I asked him to hold the acin the stall after the stall warner had announced in order to se a wing drop recovery.
Perhaps we need to reintroduce spin /stall training in a light a/c as part of an airliner LPC syllabus. And if we get to the point where noone dreads it maybe we will have moved forward.
