Abstract：To efectively evaluate the safety risk of aircraft hard landing，which is a typical unfavorable flight state，a comprehensive evaluation method of aircraft hard landing risk considering multiple coupling interaction is proposed in this paper. Correlation analysis is caried out on the preprocessed quick access recorder （QAR）data，and six flight parameters，such as altitude rate，vertical acceleration，angle of attack，etc.，are selected as the hard landing risk research factors，and thelanding risk coeficient calculation method is proposed by analyzing the data characteristics of the visualization curves.Trapezoidal fuzzy decision-making trial and evaluation laboratory（DEMATEL） method，which integrates the subjective experience of experts，is used to determine the coupled weights and optimize the risk coefficients，soas to construct acomprehensive cloud model for normal landing and hard landing segments.Numerical analysis is performed using flight data from 20 000 segments to demonstrate that the proposed method accurately maps QAR data in the landing phase to the risk evaluation space，and that the proposed method that incorporates risk weights improves the identification performance of hard landing segments significantly.
