Abstract : This report documents the results of efforts to develop that can be used for the computation of nonlinear flying quality parameters. A variety of candidate nonlinear flying quality parameters and candidate specifications for them were developed. These parameters are genuinely different from expressions derived from linearized models. They depend on the nonlinear aerodynamic functions themselves and not their derivatives, and these parameters can be computed directly form preliminary nonlinear aircraft models. Keywords: Dynamic inversion, Nonlinear inversion, Nonlinear flying qualities, Equilibrium manifold, Lift/drag ratio, Highly dynamic maneuvers.
