According to the correlation between the measured load and the flight parameters, the output error method is used to identify the end-of-flight differential load model, and the calculation model of the end-of-flight load under the flight condition is obtained. At the same time, a method suitable for the identification of flight loads is obtained. The method can study the influence of different handling laws of aircraft on the structural loads, and has high precision and is feasible and effective.
