Flight Collision Resolution Algorithm Based on ADS-B for General Aviation

To solve complex problems of conflict situations in general aviation flight, a flight collision resolution algorithm in ADS-B surveillance state is proposed. Above all, the conflict scenarios between two planes are divided into three classes, which are intersection collision, opposite collision and chase collision. And the correspondingly viable collision models for different conflict scenarios are deduced by using the heading adjustment method and speed adjustment method based on relative motion. Then the selection criteria for different release strategies are established based on the relevant provisions of the air traffic control to collision resolution, so the practical feasibility of the algorithm is enhanced. The simulation of different resolution strategies show that the algorithm is available to provide a viable solution for a specific flight conflict scenario.
