How many 777 pilots have been caught out by Boeing FLCH … is the mode the same in all models?
Probably quite a few, but as some pilot 777 admitted when he got "caught" a few times he very quickly recognized the problem and corrected it. We don't expect pilots to behave like programmed robots, mistakes do happen, we expect them to be vigilant enough to self-correct. In this particular case they had minutes (not seconds) to correct the situation, they never did.
