Abstract: The invention in particular has as an object a method and a device for centralized management of warnings in an aircraft comprising a centralized system for management of warnings (405) and a plurality of warning presentation interfaces (220?, 225?), each interface being adapted for presenting at least one warning to a user. After having determined at least one warning in the said centralized system for management of warnings according to at least one alarm activation signal received, the said determined warning is presented by a first interface (220?). The said determined warning is filtered and, in response to this step of filtering, the said determined warning is presented or not by a second interface (225?), separate from the first interface, According to a specific embodiment, the said step of presentation of the said determined warning by the said first interface comprises a step of filtering to determine whether or not the said determined warning should be presented by the said first interface.

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.
