Too many of today's trained automatons have a complete aversion of disconnecting the automatics; even when exigent circumstances require immediate manual control, they momentarily hesitate in clicking off the A/P & A/T.
Boeing says: "When the automatic systems do not perform as expected, the PF should reduce the level of automation to ensure that proper control of the airplane is maintained.
The PF should not attempt to restore higher levels of automation until after aircraft control is assured."
