Abstract: The disclosure herein proposes identifying precursors to all the phenomena which can have an impact on the service use of an aircraft. It relates to a system for predicting failures in an aircraft, including a processor configured to analyze a current behavior of at least one flight parameter of the aircraft to detect any deviation of the current behavior relative to a predetermined behavior model of the parameter, the behavior model being determined from a plurality of series of learning data relating to the parameter collected during the flights of a set of aircraft.

Abstract: A method of assistance for troubleshooting is provided. A purpose is to prioritize identifiers each associated with a piece of equipment the failure of which can be the cause of a fault within an aircraft. The method is based on transmitting to an expert system, a list of identifiers, and receiving, for each identifier, a family of pertinent parameters, with each pertinent parameter being associated with at least one sensor of the aircraft and taking measurements of the pertinent parameters. Knowing these measurements, it is possible to deduce therefrom, for each identifier, a priority corresponding to the probability that the associated equipment is effectively defective. A system for implementing this method is also provided.

Abstract: According to a first aspect, the subject matter disclosed herein relates to a decision aid method for maintenance operations of aircraft equipment, the aircraft including a maintenance system arranged to make a record of equipment failure messages and of equipment failure warning messages emitted during a flight, the method comprising extracting at least one combination of failure messages corresponding to failure messages recorded by the maintenance system during a flight and a set of previous flights; determining, as a function of the at least one extracted combination, a probability of occurrence of at least one warning message possibly accompanied by one or more failure messages.
