Can the autopilot be engaged while UAS warn is active?
Yes, but procedurally incorrect. One of the first steps of UAS is to disconnect the A/P.
Also puzzled by 'the stick shaker active' in above, is this an expected side effect of all UAS events?
Only if one airspeed/AOA was registering low enough to trigger a stall signal from the Stall Management Yaw Damper (SMYD) computer.
