I love the MSFS 787.  I notice sometimes the elevators stop working.  I see on the ground The FLT CNTR indicators show I can move the elevator to full up and down position, but while in the air the hardly move.  Is that because the FBW system is preventing me from over-stressing the plane.

But sometimes, I am losing altitude and I deed to pull up, no matter how hard I try, the elevator axis won't move.  same happens in a climb, if I push yoke forward nothing happens.  AP Pis OFF, no other elevator axis assigned.  It all works when I take off, but somewhere it (elevators) stop working. The indicators seem to "try" to move, but something forces it back to neutral.  Again, this doesn't happen all the time - I'd say 33% of the time. It just seems like something is forcing the elevators back to neutral.  Also I can't trim the plane either.  On the ground I can easily trim the plane to get to the correct trim setpoint for takeoff, but once in the air I can't trim the plane.  (AP OFF)

Do you have any AI assistance on? Doesn’t work well with complex airliners.
