Patent ID: 10502755

Abstract:
Disclosed is a method of correcting at least one result of calculating at least one flight characteristic of an airplane, based on in-flight measurements and on values calculated from the measurements, the in-flight measurements being taken in at least one determined flight condition defining a determined flight point, each flight condition being defined by particular flight parameter values, the measurements and values being in particular: θmeasure the measured pitch angle of the airplane and αmodel the angle of attack calculated by solving a lift equation and an aerodynamic model associating the angle of attack α of the airplane with at least one flight parameter, which is the lift coefficient Cz of the airplane. The pitch angle measurements θmeasure are corrected by a pitch angle correction term Δθ0 that is a particular constant for each flight, and the calculated angles of attack αmodel are corrected by an angle of attack correction term Δα(Cz . . . ).
