The model of the propeller–driven aircraft DORNIER DO 28 of the TU Braunschweig is being identified during the last years. This nonlinear, multi–point aircraft model considers the special effects which arise from the aircraft geometry and the propeller influence. Flight test data are used for identification of the physical, aerodynamic parameters, after having been checked for data compatibility. The resulting parameters show a good consistency for well prepared flight tests.
