In a crosswind, I find it quite difficult to transition from autobraking to manual braking with heels on the floor. How do you slide your feet up with constant pressure on a rudder pedal? I can’t. If I try I always lose rudder pedal pressure, and therefore a swing off the centreline.
This goes for both the RTO case as well as normal landing case. So for both takeoff and landing, I don’t like heels on the floor. However, I would like to think I would never go near to touching the brakes inadvertently.
Maybe I need to buy shoes with a more slippery sole. But then I would slip on the stairs or an oily tarmac.
