The trim should move to nose down for a few seconds as long as you are in an high angle of attack status. Once the high angle of attack has been recovered the trim automatically resets to the previous value. Any pitch trim input by the pilot and quite possibly also the auto-trim assistance will immediately cancel the activation and makes the system passive for at least 5 seconds.
Thank you very much ipacs... just one question... is the system activated with the autopilot or flying manually? Or in both cases?
