摘　　要：在军、民用飞机的飞行中,保证飞机间的安全间隔始终是确保飞行安全需要首先考虑的问题。该文以现行的飞行间隔规定为基础,以星基导航设备的使用为前提,构建了飞行冲突的判定模型———一个由保护区,警戒区组成的双层保护区域;并在对飞机之间的水平间隔和垂直间隔分别计算的基础上,实现了飞行冲突的检测算法。飞行冲突的检测算法可以提供详细的信息:何时不存在冲突;何时存在冲突;何时冲突已经发生;何时不存在冲突但存在警告,而不仅仅是给出一个判断结果。最后以该模型和算法为基础,应用遗传算法解决飞行冲突,取得了良好的效果。Maintaining safe distance is most important to insure safety in both civil flight and military flight. This paper uses current rules as the foundation and supposes navigating equipment based on satellite as prerequisite to establish a judge model of flight conflict and a conflict measure algorithm to help controllers in making decisions. Conflict measure algorithm provides detailed information about flight but doesn＇t just provide simple result of if there is a conflict. Based on the judge model of flight conflict and conflict measure algorithm, GA is used for solving flight conflict with good result.
