It does seem from the info thus far that there was a fairly abrupt nose-down shortly after TO?
If so that must be stressful for AC...?
Can STS be disengaged just like AP or AT?
Just wondering how much the pilots might have had to work against STS.
Thanks for such an informative forum.
I also am concerned that STS as an automated system that uses airspeed as an input could work against the pilot. I note in the training video above the trim wheel merrily spinning back and forth uncommanded after AP and AT disengaged. Can STS be disabled? should it be? for uas_
