Beschreibung
Zusammenfassung:	The appts includes an incidence probe (2) mounted on an aircraft is connected (4) to a calculator (3) which also receives information on the position of the flaps (10), the airbrakes (11) and the aircraft Mach number (12). A first coefficient of lift is looked up from tables determined by the received information (10,11,12). A second calculator (5) computes a second coefficient of lift from quantities such as the loading factor (13,14), the aircraft mass (15) and the dynamic pressure (16,17) and the difference between the two coefficients is determined (6). If this difference is less than a predetermined threshold the incidence probe measurement is considered to be consistent. La présente invention concerne un procédé et un dispositif pour vérifier la cohérence des mesures réalisées par une sonde d'incidence (2) montée sur un aéronef. Selon l'invention, ledit dispositif (1) comporte : des premiers moyens (3) pour calculer un premier coefficient de portance de l'aéronef à partir d'une mesure de la sonde (2) et de données relatives à l'aéronef ; des seconds moyens (5) pour calculer un second coefficient de portance à partir d'informations sur l'aéronef ; des moyens (6) pour calculer la différence entre lesdits premier et second coefficients de portance et en déduire que la mesure est cohérente ou non.
