Patent ID: 8718840

Claim:
A device for estimating an estimated fuselage angle of attack of an aircraft moving in the air, the device comprising: a sensor that measures an attack angle based on a direction of the air flowing relative to at least one point on a surface of the aircraft; a memory that stores correspondence tables, each correspondence table is associated with a different configuration of positions of lift devices of the aircraft, and each correspondence table includes entries that relate the measured attack angle and a speed information item about an airspeed of the aircraft to a corresponding estimated fuselage angle of attack of the fuselage of the aircraft; and a determining section that selects a correspondence table stored in the memory that is associated with the current position of the lift devices of the aircraft, and selects an entry in the selected correspondence table based on the measured attack angle and the speed information item about the airspeed of the aircraft as the estimated fuselage attack angle of the aircraft.
