Abstract

An index system was proposed for safety assessment of civil aviation systems. Fuzzy comprehensive evaluation method was used to calculate the safety degrees corresponding to management and to the human-machine-environment system composed of flight, support and maintenance subsystems. The comprehensive safety degree was obtained based on the above degrees, and divided into 5 grades. The system is not safe enough if the comprehensive safety degree is under grade 4. A further evaluation to the data can reveal the possible hints that cause the data to be evaluated as 'bad' or 'very bad', so that precautions can be taken accordingly.
