Dozy
In Alternate Law 2 the pilots have complete control over all aspects of the aircraft, though you're commanding pitch and roll rate unlike in Direct Law which commands deflection. In short - the pilot is in charge and the computers are specifically programmed to do whatever the pilot asks.
I think you are missing a big aspect of the crew's control problem that night.
If the aircraft is right wing heavy, the aircraft will only fly straight with continuing left stick. How easy is it to separate the roll chanel from the pitch channel in this case? This aircraft was flying in
Direct Law in roll.
Think about what this means to the lateral trim situation.!!!
NO Lateral Trim.
NO tendency to return to wings level. You must fly the roll angle full time.
Yes you have enough roll authority to level the wings.
You cannot let go of the stick-It will roll.
Do you see how a guy settling into this situation might apply nose up at the same time???
If not, do this experiment:
Place right arm on table in front of you. Point thumb up.
Put a stick in hand. Tilt stick to left.
With opposite hand, resist the attempt to tilt stick. Do you accidentally tilt stick toward you?? If not, apply more force until you have to cup stick in hand instead of with finger tips.
Get the idea?
