Abstract

In order to prevent and control flight risks, construction of safety risk matrix and probability theory are used to study quantitative analysis method of flight operational quality risks. Firstly, probability and severity of events were obtained based on probability density function of normal distribution after normalizing skewed data. Then, a risk measurement method for flight operational quality was put forward based on the idea that "risk is a product of probability and severity". Finally, flight risks were measured from four different perspectives: light, medium, heavy and comprehensive, and QAR data were used to analyze and verify the method. The research shows that the proposed method can integrate probability and severity of events and measure four types of flight risks.

RESULTS obtained from it can be used to guide differential management of risks. © 2019 China Safety Science Journal. All rights reserved.
