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 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 method of preventive maintenance for an aircraft, the aircraft having components, including items of equipment of the aircraft and/or electronic modules and/or physical links. The lifetime information for the components is known. The aircraft also includes means for monitoring the components, a centralized maintenance system, and means for estimating the life time of the components. The aircraft carries out a set of functions, each being ensured by a chain of components. The method comprises several steps including, a first step of locating the degradations of the items of equipment, a second step making it possible to allocate the located degradations to the various functions of the aircraft, a third step of estimating the lifetime of the functions identified in the second step, and a fourth step of formulating the maintenance message constructed on the basis of the previous steps.

Formulation of a preventive maintenance message relating to the functional degradations of an aircraft

A centralized maintenance system for aircraft which includes line replacement units (LRUs). The system includes at least one digital database whose data are information relating to the LRUs; and a device for updating the data of the database. The lifetime information for the LRUs is known and contained in the digital database. The database includes a mean time between failure (MTBF) data of each LRU. The MTBF data is able to be modified and updated, according to at least one event modifying the failure probabilities for at least one LRU.

System for centralized maintenance of onboard electronic equipment

The present invention concerns a method and a system for filtering tracks originating from several sources and intended for several clients to which they are supplied. The method comprises at least a phase () for establishing a link between tracks resulting from a single aircraft and a phase for selecting one of the linked tracks to represent the aircraft according to a client-dependent criterion, so that a single client may not receive several distinct tracks representing the single aircraft but so that distinct clients may receive distinct tracks representing the single aircraft.
