Airplane controlling

Do us all a favour and get yourself a joystick

believe me all the joysticks are not better and easier than mouse and please answer my question otherwise dont....ok

I'm not too sure what you mean. If you mean moving the plane while on the ground by moving the mouse, I don't think that is possible (but it may with a program to set the mouse to emulate a game controller). If your talking about controlling it (buttons and so on), just click them in the cockpit. I would recommend a joystick (or other controller) though for controlling (although I use an Xbox 360 controller) as controlling the aircraft via the mouse or keyboard is quite difficult

I think 2002 was the last time the FS was controlled by mouse.
There was an add-on for FS9 that someone wrote but as for FSX, I can't say yet.

If you have realism settings on max then the only way you can turn the aircraft on the ground is by using the rudder.
