Thanks for that last report punkalouver.
I can see now there are 2 schools for that matter, I would not have thought so. As sheppey wrote, the FCTMs do not seem to specify anything on that subject. My way to do it is heels on the floor, toes clear of the brakes as long as braking is not necessary. That's the way I've been teached and I'm very comfortable that way. It provides me a more accurate control, like the need to use the armrest to get a more precise control on the sidestick.
But actually I don't know how are doing the guys I'm working with, so I will take a few months to observe and question, and I'll be back here to report ...
