I'm using the POSKY 757 with the LevelD panel. From time to time I find that my elevator trim runs wide and goes to a full up position. I've got failures set to zero (no failure). I try to disable the elevator trim by activating the guarded switches on the throttle panel but that does nothing.
I get no EICAS warning message and everything else seems fine (hydraulics). I'm completely at a loss to figure out what to do.
Has anyone else had this problem? Have you found a solution?
