Where Is My Plane

[bolox]

You can't 'place' planes directly where you want them, - airfields have their behaviour coded.

You say your planes are a long taxi away from runway. This leads me to believe 'spawn parked' is ticked in the properties box?
If you want to start on the runway 'ready to go' untick this check box.

If you want to use spawn parked but want to move plane(s) to a different place you must 'cheat' by placing static objects over the 'parking places'- this includes inside hangars on some airfields.
