US 2004/0111193 A1 · Process and device for detecting the failure of a pressure sensor of an air data system of an aircraft

Abstract

Process and device for detecting the failure of a pressure sensor of an air data system of an aircraft. The device (1) for detecting the failure of a process sensor (5) of an air data system (2) of an aircraft comprising at least two pressure sensors (5), comprises means for acquiring the values of measurements made by the pressure sensors (5), means for calculating the deviation between the values thus measured, means for comparing this deviation with a predetermined threshold value, and means (13) for displaying, if said deviation is greater than said threshold value, a failure cue relating to the air data system (2) on a display device (15) which is mounted on the aircraft.

A process for detecting the failure of a pressure sensor (5) of an air data system (2) of an aircraft, which comprises at least two pressure sensors (5), wherein at least the following first series of steps is carried out:

A1) pressure measurements are made with the aid of said two pressure sensors (5) so as to obtain, respectively, first and second pressure values;
A2) the deviation between said first and second pressure values is calculated;
A3) this deviation is compared with a predetermined threshold value;
and
A4) if said deviation is greater than said threshold value, a failure cue relating to said air data system (2) is displayed on a display device (15) which is mounted on said aircraft:
