For some reason I can't turn autothrottle off. I press D to turn it off and it well say ATS off. But then I still have no control of the throttles. No matter what I am doing the throttles well be out of my control and I well stall most of the time. And also what I can't do is when I am in Auto Flight Mode and when I select a heading nothing well happen. :(And when I turn and then set auto flight again the plane well automaticly turn to 309, even though I don't want it too. :(

I wonder, are you perhaps refering to a Spitfre - a Cessna 182? People here are not mind readers:-)

You need to sign your name per policy. You also need to provide more information. I presume you are trying to fly the MD-11. Per manuals, in order to select manual heading, you need to "pull" the button, etc...I suggest you go through the tutorial.Fabio

CTRL+Z is the normal command to disconnect the ATS, unless otherwise assigned, if you are indeed flying the MD-11. Try that. If you assigned that command to another key, try switching it back to the default.As far as operating the GCP and AT/AS systems go, RTFM, this is basic stuff.
