Ah, Machinbird, I'd separated the roll and the pull up as two different problems. The roll correction should be automatic. The pull up was wrong. So I suppose "do nothing at all" is probably wrong. Correct roll once you recognize it is real and then do nothing about speed.
And, of course, doing nothing about communications with DAKAR or Brazil trying to reach the plane without using selcal is also the wrong thing.
All that said, if the roll was not dramatic, why not wait a half dozen or dozen seconds to see what happens? The ride for the SLF might be a little rougher. But, they might have lived through it. Diagnose then do. "Don't just do something (reaction), sit there( think), then do (action)."
It will be interesting to find out how fast the plane rolled when the AP kicked out. Was it urgent? Was it slow enough to ask why then act? That much tonnage seems like it'd take quite awhile to develop a really sincere roll or pitch change absent strong control surface actions. Is my intuition here right?
