【 摘 要 】

The authors consider the algorithmic and methodological support for estimating nonlinear dependencies when performing the parameter identification of the aircraft mathematic models using the flight test data. Examples of the considered methods practical application to identifying the nonlinear parameters of several modern aircrafts are presented.
