Method, device and system for analyzing flight quality of aircraft

The invention provides a method for analyzing the flight quality of an aircraft, and the method comprises the steps: receiving flight data, and carrying out the hierarchical management of the received flight data; collecting parameter decoding rule configurations of various types of aircrafts and performing hierarchical management to construct a parameter decoding library suitable for the various types of aircrafts; performing parameter matching decoding of the flight data according to a parameter decoding rule of the same level to generate engineering value data; key points and intervals are constructed, threshold values corresponding to the key points and the intervals are set, and judgment and analysis rules are written; reading fragment engineering value data corresponding to key points and intervals in the engineering value data, comparing the parameter engineering value data with preset thresholds of corresponding parameters, and then detecting event contents in the fragment engineering value data based
