The method of identifying a flight profile of an aircraft, the aircraft including a centralized maintenance system and an item of equipment including a component designed to measure the environmental conditions, comprises:

Methods of identifying flight profiles in aircraft maintenance operations

The invention relates to a device for system diagnosis of an aircraft. The device includes: means for the monitoring of equipment of the system, the means for emitting messages of observations on the basis of effects produced by equipment; means for the determination of a set of observations on the basis of the messages of observations arising from the monitoring of a log of the messages of observations and of a model representing a current state of the system; means for the determination of indictments on the basis of observations of the set of observations and of a behavioral model of the system, the indictments being logical relations between operating modes of equipment having produced effects; and means for the determination of maintenance operations on the basis of the indictments.

Device for system diagnosis

The invention relates to a method for aiding the maintenance of a system, the system comprising a set of networked elements, the system being accompanied by indications defining subsets of networked elements E, each subset of networked elements Ebeing associated with a probability of failure P, the including the steps of calculating a first value Tfor each subset of networked elements E, the first value Tincluding an estimation of the maintenance time related to the repair of the subset of networked elements E, calculating a second value Ffor each subset of networked elements E, the second value Fincluding a representation of a compromise between the estimation of the maintenance time Trelated to the repair of the subset of networked elements Eand the probability of failure Pof the subsets of networked elements E, and sorting the designated sets of items of equipment Ein order of decreasing second value F.

Method and device for aiding the maintenance of a system

The subject of the invention is a device for managing equipment maintenance. It relates to a device for managing maintenance of a number N of items of equipment EQi built into a system, i designating an index identifying the item of equipment EQi and lying between 1 and N, the system furthermore comprising a main computer RC, the equipment EQexchanging data with the main computer RC through a communication network, the equipment EQbeing capable of being built into the system or of being removed from the system, each item of equipment EQbeing protected by a protective housing BP, the communication node Noccupying a position internal to the housing BPand being devised to exchange data with the radio tag ET, the radio tag ETbeing fixed securely to the housing BPand being devised to deliver data through a contactless link.

Device and method for managing equipment maintenance

A rapidly installable and rapidly removable set of equipment (-) which can be replaced by standard exchanges, furnished with individual electronic circuits for monitoring proper operation (---) assuming, at their level, a BITE function (Build [sic] In Test Equipment) for testing, for fault diagnosis and for issuing fault messages sent by data transmission to a central maintenance computer () itself formulating a report regarding the overall state of operation of the set of equipment. It relates more especially to the hardware parts of the electronic circuits for monitoring proper operation which are integral with the equipment (-) or with equipment parts (--) and which are furnished with a nonvolatile memory () and by means of detection, selection and capture () into their nonvolatile memories (), of the report formulated by the central maintenance computer (). Since these hardware parts of circuits for monitoring proper operation track the tribulations of the equipment parts or pieces of equipment with which they are integral, they make it possible for the latest report regarding the overall state of operation of the set of equipment often causing the removal, to be always available, in a repair center, with an item removed for repair, thereby facilitating the drawing up of a repair diagnosis.
