METHOD FOR SELF-TESTING AN ANGLE-OF-ATTACK PROBE AND METHOD FOR CHECKING THE VELOCITY OF AN AIRFLOW PROVIDED BY A SERIES OF ASSOCIATED PITOT PROBES AND ANGLE-OF-ATTACK PROBE

摘要

The present invention relates to a method (100) for self-testing an angle-of-attack probe comprising the steps of controlling (110) an angular excitation of a rotary element that is rotatable about its equilibrium position according to known excitation characteristics; acquiring (120) angular measurements relating to the rotation of the rotary element, determining (130) a parasitic torque applied to the rotary element on the basis of the angular measurements and of the excitation characteristics; comparing (160) at least one component of the parasitic torque with at least one predetermined threshold and detecting (170) an operating fault in the probe when said component exceeds the predetermined threshold.
