Abstract There are many factors on different levels which affect aircraft flight safety evaluations as there are many uncertainties and significant mutual interference between the level’s, so it is difficult to attain accurate measurements. In consideration of these flight safety complexities, in this paper, a fishbone diagram is first used to analyze four main factors; the pilots, the aircraft, the environment and the management. We then introduce an innovative method called the ‘Multi-factor Comprehensive Safety Risk Evaluation’ which allows for the introduction of a more reasonable entropy weight by combining objective data and subjective expert preferences to decide the weight coefficients. These results are then combined with safety system engineering to develop a reasonable but fuzzy flight safety evaluation index by building a “combination empowerment—fuzzy comprehensive evaluation model”. From the view of the “human-machine-environment-management systems theory”, it is then possible to evaluate accident probabilities to ensure flight safety classification grading control. Finally, combined with the safety evaluation information and suggestions from airline personnel, the above model and method are verified.
