We study on a method of how to create 3DCG animation of aircrafts easily. Our target in this paper is an animation of air show from many kinds of aircraft animations. In the air show, there are two kinds of performances in general. One is group flight and the other is sole flight. We focus on the latter. We propose a method to generate flight course of those who aren't principal aircrafts automatically during solo flight. This method satisfies synchronization and smoothness of the curvature.
