Study On The Management Oversight And Risk Tree Of The Air Traffic Service System

The article can be divided Into following parts:First, Introducing the development and existing situation of air-traffic service and aeronautics safety, directing the potential and great Insidious danger caused by disco-ordination between air-traffic service and aeronautics safety and aeronautics development, analyzing the causes of accident. Second, Introducing the related theory of safety and safety systematic engineering and methods of analyzing accident. Third, based on the above content, analyzing the factors that affect the safety of air-traffic safety management, especially the human factor. Finally, using MORT to improve the air-traffic management safety.The analytical model of the MORT and user's manual have been compiled.The using of the analytical model of the MORT and user's manual can not only find out the defects and omissions in the existing safety management system, but also improve the safety situations, so that the safety management for the air-traffic can be raised to the modern level.
