In the paper some aspects of aerodynamic characteristics modifications at high angles of attack and big angles of sideslip are considered. Model is based on results of wind tunnel and flight tests and allows to reproduce dynamics features at stall AOA: hysteresis of aerodynamic characteristics, asymmetric disturbing forces and moments at wing and tail, appearing of buffeting.
