A330 Manual Pitch Trim
The manual pitch trim is mechanically connected to the THS. That THS is pretty big.
Just out of curiosity - approx. how many revolutions of the manual pitch trim would it take to bring the THS from the max nose-up angle (12 degrees) to an angle where elevator authority is sufficient to command pitch down (8 degrees I recall). What about 0 degrees?
What force is required to move the pitch trim wheel? It says: "Mechanical connection", but is there some kind of power assist?
If the THS jammed, would the wheel also jam? Can icing cause the THS to jam?
What is the relation between manual trim and autotrim? If I manually trim does the autotrim disengage? When does it re-engage? What if autotrim is commanding nose up and I trim nose down - who has the last word?
