Flight Approach Landing Maneuver Performance Evaluation Method Based on Entropy Weighted AHP-FGCM
In order to objectively and quantitatively assess the flight approach and land-ing maneuvering performance,a comprehensive assessment method of flight approach and landing maneuvering performance based on entropy-weighted hierarchical fuzzy gray clus-tering(AHP-FGCM)is proposed.Considering the main manipulate characterization of the approach and landing such as pitch,lateral and yaw,the actual aircraft approach and land-ing flight data of a flight training college was collected and analyzed.Then,7 indicators such as lift rate,pitch attitude,lateral acceleration and so on were picked out as the ap-proach and landing manipulate performance evaluation indicators,which was in accordance with the civil aviation flight quality monitoring Advisory Circular(AC)and Delphi method.The entropy weight hierarchy method is used to determine the combined weight,and the fuzzy gray clustering is used to comprehensively evaluate the approach and landing flight control performance.The evaluation results of the examples are consistent with the actual manipulation performance level,which proves the objective validity of the method.
