I wonder what the bus would have done if he had used a handful of nose up trim to get the nose up?
Golden
In Normal or ALT Law, the elevator position is controlled by the FBW computers. I think if Sully had added stabiliser trim, then the elevators would have moved in the opposite sense in order to maintain the same Alpha.
I am afraid none of that is going to happen. See below:
DSC-27-20-10-20 P 1/8


When angle-of-attack protection is active, the THS setting is limited between the setting at the aircraft’s entry into this protection and 3.5 ° nose down. (Neither the pilot nor the system can apply additional nose-up trim).
