To quote from Airbus...
"Except in emergency situations, AP and A/THR must not be overridden manually."
Just curious whether this applies to any other types. I have seen it done for a few moments on Boeings.
Done it on Boeings (B737-777) and MD/DC planes when the automatics didn't wanna do what i wanted it to.
I guess it's all up to design philosophy.
