The main function of the system is described, and data types of database and the operation modules of model-base are also discussed. The flight path marking model, protected-area auto-generating model, obstructer extracting model, obstructer threat evaluation model, flight conflict avoiding model and flight ordering model are used in flight procedure management. After sufficiently elucidating the system structure and function, the assistant decision-making process supported by the system for chief officers is analyzed finally.

First, the angular velocity function and maneuver load for certain maneuver flight (including hover, dive-hike and these two combined) are set up. The simulation results of the vibration of double-disk rotor system with cantilever supported on rigid bearings show that rotor would be apparently deformed under maneuver load. Second, the performance of oil force of SFD in maneuver flight is analyzed. The results show that in maneuver flight, the SFD with centering spring will become eccentric and its oil force will be time-related and offset-related. Then, SFDs are introduced into typical Jeffcott rotor system. The whole system will be statically displaced in maneuver flight and the nonsynchronous components of oil force appear in the response of rotor system.
