Flight quality evaluation method and system based on entropy weight

The invention discloses a flight quality evaluation method and a flight quality evaluation system based on entropy weight, which utilize data of QAR equipment to evaluate flight quality, avoid division of unsafe events by an original threshold comparison method, and avoid one-sidedness caused by whether an event occurs or not or comparison by a single parameter. According to the technical scheme, the method comprises the following steps: setting flight quality evaluation dimensions, respectively establishing corresponding flight quality evaluation parameters under each flight quality evaluation dimension, and setting a corresponding threshold value for each flight quality evaluation parameter; carrying out segmented exponential transformation on the parameter values of the flight quality evaluation parameters, and carrying out corresponding processing according to whether the larger the parameter values are, the better the parameter values are or the smaller the parameter values are; carrying out standardizat
