Abstract：A data-driven ideal landing trajectory construction and evaluation method is proposed,taking the flight training da-ta recorded by the avionics equipment of a small general aviation aircraft as the research object.After extracting the landing phase data,abnormal landing data is filtered out.The ideal landing curve is constructed through the quadratic optimal approximation mod-el.And finally,the evaluation index and model of"area-angle dual-dimensional deviation"are proposed.The results show that 82.4％of the landing trajectory deviations are less than 33.3％,which verifies the rationality of the ideal curve construction and the effectiveness of the evaluation method.It provides a data-driven quantitative basis for flight training quality evaluation,which has practical and reference significance for improving the standardization of carrier-based aircraft operations.
