Abstract

The invention discloses a landing operation performance evaluation method based on flight data. The method comprises that a QAR system collects landing distances, landing loads and landing elevation angles of multiple flights of the same type within certain historical period, and predicts parameter distribution; the risk values of abnormal landing events including distant landing, heavy landing and tail strikes are calculated; a landing operation performance evaluation model is established according to the risk values of the three abnormal landing events and weights thereof; and the evaluation model is used to calculate a landing operation performance evaluated value of certain flight, and an evaluation result of a landing operation performance level is output according to a division standard of the landing operation performance levels. According to the method, the landing operation performance of the single flight is evaluated in an integrated manner, the risks of landing events of the single flight or in certain period can be predicted, and the landing performance of the whole fleet or airline can be evaluated and compared. In addition, the invention also provides a landing operation performance evaluation device based on flight data.

Description

technical field [0001] The invention belongs to the technical field of flight quality monitoring, in particular to a landing operation performance evaluation method and device based on flight data. Background technique [0002] Flight accident statistics show that landing is the most dangerous stage of civil aircraft flight, and the incidence of accidents and unsafe incidents is significantly higher than that of other flight stages, because during the landing process, pilots need to face more operational tasks and the resulting Workload. The pilot's operation is closely related to landing safety, so an accurate evaluation of the pilot's operational performance level can provide a direct basis for evaluating the operational risk and overall safety level of the flight team, and provide an important reference for improving flight operations and training. [0003] However, how to accurately evaluate the operational performance of pilots has always been a difficult problem for a...
