PROCESS AND DEVICE FOR VERIFYING THE CONSISTENCY OF THE MEASUREMENTS FROM AN ANGLE-OF-ATTACK PROBE

A process and a device for verifying the consistency of the measurements made by an angle-of-attack probe (2) mounted on an aircraft. The device (1) includes: first system (3) for computing a first coefficient of lift of the aircraft from a measurement from the probe (2) and from data relating to the aircraft; second system (5) for computing a second coefficient of lift from information about the aircraft; system (6) for computing the difference between the first and second coefficients of lift and for deducting therefrom that the measurement is or is not consistent.
