Thanks all. I'll try NASA Ames and FSF, its just that it was the weekend and I thought someone could point me in the right direction.
There has been research done on this subject (about 20 years ago!) , the manufacturers have a reason for recommending a specific practice (and its what all the airlines do).
The way most do it as stated on this forum is the norm...ie. AP ON - PF does it otherwise PNF does it.
I'm faced with having to defend the norm against a planned change where they want they want PNF to do it ALL times - no exceptions. None of our various manufacturers have a recommended practice.
Indeed, in the big scheme of things, this is a trivial matter but surprisingly, it has polarized our crews.... ahh well, I guess I'll still live.
No more posts please..if anyone has any information, then pm me please.
Thanks for taking the time to post.
