On fast identification problem of the aerodynamic aircraft characteristics solved by means of current flight parameters recording

The problem of fast aircraft aerodynamic characteristics identification performed by means of current flight parameters recording is presented in the paper. Basic concepts of fast identification algorithms; e.g., Nonlinear Filtering (NF) (based on the Lipcer and Sziriajev theory) and Estimation Before Modelling (EBM) are presented, as well.

Tips on how to implement EBM and NF methods in practice are shown, as well. The numerical results presented seem to be very interesting.
