With the criterion of the minimum fuel or the time used in transition maneuvers of flight test, this paper studies the optimal ordering problem of flight test maneuvers by genetic algorithm (GA), which is based on the mechanics of natural selection and genetics. The basic principle and technique of genetic algorithms on the optimal ordering problem are presented. In order to solve the specific optimal ordering problem of flight test maneuvers, it establishes the proper fitness function and improves the selection operator and cross operator of genetic algorithms. The advantages of GA, such as its engineering flexibility and extensive application range are utilized. The results showed that reasonably arranging the sequence of flight test maneuvers by GA can make best use of fuel and time available in flight test, then the cost is saved and the efficiency of flight test improved.
