Tyro:
The point I wish to make to smilin-ed is that you cannot feel if the a/c in in trim (except in Direct Law). Autotrim was not the reason for this accident.
Tyro, I am well aware the truth in both of these statements. My points are:

1.In my opinion, not having any change in the feeling of the side stick as flight conditions change makes it harder to trim properly. Some people seem to think otherwise, but that is their opinion. This, however is not even a contributing cause of this accident.

2. Autotrim did not cause the accident since the person flying did not even try to recover from the stall which he caused by his persistent nose up inputs. However, if he had tried to recover from the stall it would have been more difficult because autotrim caused the THS to move to the full nose up position. It would have taken more time to attain a nose-down pitching moment than if trim had stayed at the cruise setting.
