Re: Aircraft Systems

But the trim wasn't running away, it was moving a bit and then stopping which it does in normal operation. Probably on occasion it stopped when the pilots did something they expected would counteract the automatic trim and it appeared to work. If it was the only problem they had to deal with then it might have been a higher priority, but there was also an airspeed indication mismatch and a stick shaker active on one pilot's controls. Figuring out that a bit of trim movement is the most pressing issue would have been helped by knowing MCAS existed and has full authority over the stabiliser.
