Dynamic flight test techniques may be employed for the measurement of a variety of aircraft performance characteristics as well as for the measurement of Stability and Control characteristics in the form of for instance classical stability and control derivatives. The present work focusses on the development of nonlinear aerodynamic models from dynamic flight test data. Several closely related characteristics of these models are discussed in detail such as goodness of fit to flight test data, the accuracy of model predictions and model complexity. Results are presented of a flight test program with the DHC-2 beaver experimental aircraft of Delft University of Technology equipped with a high accuracy instrumentation system. Different aerodynamic models are compared with results from wind tunnel experiments.
