Abstract: A method and system for determining an estimation of an anemometric parameter of an aircraft. The anemometric parameter including an angle of attack, a sideslip angle and a calibrated airspeed. The method including obtaining an indication of a secondary surface state of the aircraft; obtaining a position indication of a horizontal primary surface; obtaining a load applied estimation on a corresponding actuator using the position indication of the horizontal primary surface and the position of the corresponding actuator; accessing a lookup table with the indication of the secondary surface state of the aircraft, the load estimation applied on the corresponding actuator, and the position of the corresponding actuator; obtaining an estimation of the anemometric parameter associated with the horizontal primary surface; providing the estimation of the anemometric parameter associated with the horizontal primary surface and wherein the lookup table is generated during a learning phase.
