Also, the Perpignan A320 was, I think, being piloted by very highly experienced Type Rating Examiner; the guys who really know their aircraft inside out.
I agree with the assessment above, something not good about THS's that trim themselves full or nearly full NU and then remain there when it might be appropriate for them to auto-nose down to help overwhelmed pilots in the heat of battle with FBW systems..... not to mention stall warnings that shut down at slow speeds, then warn again as airspeed increases... brilliant.
I am not a fan of autotrim in the 777 either.
