A method is provided for determining the speed of the mean wind with respect to the ground during the flight of an aircraft. At each time of rank i of a succession of n times spread out over a flight period, the modulus Vi of the air speed of the aircraft and the three components SNi, SEi and SVi of the ground speed of the aircraft are measured. Then, using the method of least squares, the system of n(n-1)/2 equations with three unknowns WN,WE and WV is solved: 2(SNi-SNj)WN+2(SEi-SEj)WE+2(SVi-SVj)WV =SNj2+SEi2-SEj2+SVi2-SVj2+Vj2-Vi2 (5) in which WN,WE an...
A device for providing the three components WN, WE and WV, in an Earth reference frame, of speed with respect to the ground of the wind during a flight period of an aircraft, for use by equipment of said aircraft which is sensitive to the wind, comprising: means for measuring including an anemobarometric sensor and an inertial unit which comprises accelerometers, at each time of rank i of a succession of times spread out over said flight period, a value Vi of the modulus of the speed of said aircraft with respect to the air mass in which it moves and val...
