Research Abstract	Evaluation by a human pilot of the aircraft flying and handling qualities in terms of the subjective pilot rating needs to be justified by objective data pertaining to pilot control characteristics. Letting the pilot linear control behavior represent his control characteristics, this project has extended an identification method so that it may treat complex multi-input, multi-output systems such as include an inner loop. The extended method utilizes the Autoregressive scheme, and determines the unknown dynamics by reducing the concerned system to the feedback structure suited to the scheme. Distinguishing an assumed system structure from other candidates of system structure is also possible by examining the correlation characteristics of the innovation processes as well as the identified dynamics. The method has been tested by a digital simulation study and a series of simulator tests involving human pilots. Results from the tests show that the method is feasible enough to be applied to flight test data. Application of the method to various flight control situations may further define the objective evaluation of the aircraft flying and handling qualities.
