Today I have flown from Shanghai to Los Angles.When I disengaged the Autopilot at 10000ft,I found that I cannot have my elevator controlled,it seemed that the elevators was in the situation of Pitch Hold.After several tries,I simply shut off the LSAS and got elevators work properly. Same problem have happened to me weeks before,when I flew from Heathrow to Nice,and I used the same method to solve the problem. Another thing I must say is that my joystick does have some problem of banking left,but so far I haven't got any difficulties in Longitudinal control.

Oh I thought this might have been about the aircraft flipping inverted after a hard landing. :(

Well,I usually just shut down the FS when one flight completed,so there's no chance for a hard landing to do any impact to the plane.
