Abstract:

Carrier-based aircraft landing is a complex process, its safety largely depending on the control deviation of the pilot which is again influenced by a combination of the state of the physical condition of the pilot, the environment and the equipment (carrier-based aircraft). Taking a certain type of foreign carrier-based aircraft as an example, this paper provides a method of carrier-based aircraft landing process safety modeling and simulation based on fuzzy inference. The uncertainty of pilot control during the process of carrier-based aircraft landing is considered, and this method analyzes the influencing factors of the uncertainty from the point of view of human-machine-environment. A hazard model is presented based on fuzzy inference, on the basis of this model, a safety simulation model of the landing process is proposed. And then the degree of influence of key factors, such as hazard mode, criticality, and hazard occurrence time, etc., is determined from simulation analysis which lays the foundation for safe carrier-based aircraft landing.

Key words: system safety, carrier-based aircraft, landing, safety simulation, fuzzy inference
