Can the -400 autopilot be lightly overpowered without causing an automatic disengagement of the auotpilot? If so at what point would the autotrim run?
Hypothetical scenario: early capture of GS; autopilot demands climb. Crew overpowers autos to maintain altitude causing the trim to run nose up; subsequently autopilot disengages / is disengaged, resulting in a large nose up pitch change. Trim change accentuated by speed reduction / flap deployment.
