Thanks MemberBerry, #3655
Your helpful description, interpretation of the EASA text, infers that the trim demand will be as required for the flight condition. Even in extreme ‘normal flight’, in-trim conditions, the trim system should not hold any significant load other than that required for a balanced aircraft, which will fly ‘hands off’.
The situation with MCAS malfunction is that the flight condition is not balanced - ‘abnormal flight’; the trim system is creating the flight path deviation which the crew are attempting to correct. A correcting force has to be applied via the trim motor and elevator; these forces are probably much higher than that for the near trim condition.
Thus are the differences in the required force and direction of motion, at or beyond the capability of the trim elect motor ?
The apparent anomaly towards the end of the FDR could be interpreted as a nose up elect trim demand, but no trim movement, yet shortly after MCAS trim demands nose down and the tail moves. This of course is not evidence of a nose up elect trim limit (stall), but remains a possibility.
Is this above a valid position, is it one which the EASA (FAA, Boeing) text might not have considered ?
