Hello,One major problem here: Most of the time after a landing and under taxieng, the throttle goes automaticly on full throttle?After hitting the F1-key it 'still' want to go at full throttle???(after hitting the F1-key a several time's the PIC finaly listen.....but then I'm most of the time at the end of the runway in the grass :(Also the speedbrake wont listen? After giving max speedbrake after landing the speedbrakes goes up again automaticly? Ive try the PIC on two differend systems one AMD and one Intel!On both machines the PIC reacts the same???Thanksvortovor

Off the top of my head it sounds like you still have your autothrottle armed as well as the autopilot.If you are landing manually you must disarm the autothrottle and disengage the autopilot before landing.As for the speedbrakes are you referring to the handle or the brakes themselves? Fyi the speedbrakes deploy automatically upon landing. Hope this helps.

If the speedbrakes are armed they will deploy upon touchdown. They will also deploy upon engagement of reverse thrust.For the original poster; could it be the throttle on your joystick interfering?
