The mathematical model of the system has been set up. On the basis of it, the simulation research was made to the system by adopting the real-time distributed simulation system. It has also given the structure scheme of the real-time distributed system and discussed the questions of simulation algorithm, the selection of simulation step, and so on. The simulation result under the circumstances of dry and wet runway of a certain aircraft anti-skid braking system has been analyzed. The experiment verified that the real-time distributed system possessed the advantages of good realtime distinction,strong processing ability, and so on.
