Abstract:
1. A method of determining anemometric parameters of an aircraft (A), said method using at least one laser anemometer (A 1 to A 4 ) that is capable of measuring the wind speed along a laser axis (L 1 to L 4 ), in which four laser anemometers (A 1 to A 4 ) are mounted in pairs (CA, CB) on the aircraft (A), said pairs (CA, CB) being mounted symmetrically relative to a vertical plane (P 0 ) that corresponds to a plane passing through the longitudinal axis of the aircraft (A) and orthogonal to the general plane of the supporting surface ( 2 , 3 ) of said aircraft (A), and in which: using each of said laser anemometers (A for each pair (CA, CB) of laser anemometers, the two measurements (V using the two duly calculated speed vectors (VA, VB), and at least one reference table, the respective values of the angle of incidence and the angle of sideslip of the aircraft (A) are determined.
