To assess the flight qualities of a modern aircraft with flight control system, it is a widely acceptable way to match its dynamics with that of a low-order equivalent system. In this paper, five kinds lateral and directional dynamics models of low-order equivalent system are abstracted according to the latest handling qualities specifications and other relative information. Their structures and usages are investigated, and then some example aircraft are used to test the validity of the models and the...

To assess the flight qualities of a modern aircraft with flight control system, it is a widely acceptable way to match its dynamics with that of a low-order equivalent system. In this paper, five kinds lateral and directional dynamics models of low-order equivalent system are abstracted according to the latest handling qualities specifications and other relative information. Their structures and usages are investigated, and then some example aircraft are used to test the validity of the models and the matching methods. Some problems which were found in the process of matching are discussed and the possible solutions are suggested. All of them are expected to be helpful in studying and evaluating the lateral and directional flight qualities.
