Hi Sham
Why don't you just generate them at random? They operate at all heights,speeds, distances, destinations,etc, so why not generate your movements at such random condition.The only Corps aircraft that follow airline-style movements and operations are the VIP aircraft,which, in effect, are corporate aircraft, which means that generating a facsimile of their movements is probably something that has already been done for sims.The other aircraft fly at speeds, altitudes,etc appropriate to GA aircraft, except for unusual movements like high-speed aerobatics and gunnery training.
