Abstract:

In the flight management system,the analysis of flight leg and the construction of transition path have to be realized based on the fight plan in order to obtain a proper path for horizontal navigation. The construction of transition involves the processing of two types of transition,standard leg transition and the special "fish-bird"transition. The present paper provides an analysis of the formation machanism of "fish-bird"path and proposes a judging method as well as a processing method. Based on this,a construction algorithm of transition between different types of legs is proposed,and the analyzing process of flight plan is produced. It is demostrated by the simulation that the proposed algorithm could effectively perform the leg analysis and construct the proper transition path.
