The maximum likelihood parameter estimation method for nonlinear systems is applied to estimate from flight data at a few selected flight conditions the aerodynamic derivatives of the ATTAS (Advanced Technologies Testing Aircraft System). The coupled equations of aircraft motion pertaining to the longitudinal and lateral directional motion in the wind axis system and an aerodynamic model in terms of nondimensional derivatives are employed. In addition, details of the specially carried out flight maneuvers which enable separate estimation of the two pitch damping derivatives due to the pitch rate and rate of change of angle of attack from flight data, are provided.
