Tom,
I flew with a Boeing test pilot of 30 odd years on a recent C1 flight. I asked him a few questions and then whinged about pilots having so many theories on things. This is his qwote back to me, "son, theories are like xyzholes, everyone has one." Pretty nice I thought.
But what I am getting at is, that even in Boeing they have different theories on what we are talking about. I specifically asked a test pilot who was head of training standards 737 about calling V1 early. She said not to, that there was a 2 second reaction time for Mr Average etc.. So as time goes by the Boeing symposium you were at becomes history (which will repeat itself of course) and as new people take up their posts they forward their own theories.
This is a great game isnt it?
