ABSTRACT:
Detection of the failure of a pressure sensor of an air data system of an aircraft having at least two pressure sensors includes measuring first and second pressure values with the aid of the two pressure sensors, respectively. The deviation between the first and second pressure values is calculated, and this deviation is compared with a predetermined threshold value. If the deviation is greater than the threshold value, a failure cue relating to the air data system is displayed on a display device that is mounted in the aircraft.
