Abstract: A scheme for conflict resolution with dynamically changing the speeds of two or three aircrafts flying on the two air flows in the same flight height was proposed. The positions of the aircrafts and the distance between them were dynamically checked while the aircrafts entered the alert area, which was a circle plate around the intersection of the two air flows. The scheme computed the distance between the aircrafts and the intersection firstly. Then the coordinates were set up according to the distance computed on last step; therefore, the coordinates became the aircraft coordinates with small distance. The speeds were adjusted according to a set of partial differential equations and optimal control theory. The experimental results show that the scheme is safe.
