Abstract

A centralized maintenance device installed on-board an aircraft notably carries out the following functions: correlation of data relating to failures, warnings, configurations, operational contexts, flags and the logbook, received by the on-board maintenance system; storage of the data received by the on-board maintenance system in a first database; management of a historical record of the data received and of their correlation; transmission to a man-machine interface of the data received, of their correlation and of a date associated with each item of data; display of the received data, their correlation and the date associated with each item of data, by a man-machine interface of the on-board maintenance system.

Claims

1. A centralized maintenance device installed on-board an aircraft, taking account of data relating to:

failures originating from systems of the aircraft;

warnings coming from a warning system of the aircraft;

configurations of the systems of the aircraft;

operational contexts of functioning of the systems of the aircraft;

event flags, set by a crew of the aircraft;

a logbook, filled in by the crew of the aircraft;

the said on-board maintenance system also carrying out the following functions;

correlation of data relating to failures, warnings, configurations, operational contexts, flags and the logbook, received by the on-board maintenance system;

storage of the data received by the on-board maintenance system in a first database;

management of a historical record of the data received and of their correlation;

transmission to a man-machine interface of the data received, of their correlation and of a date associated with each item of data received;

display of the received data, their correlation and the date associated with each item of data, by the man-machine interface of the on-board maintenance system.

2. The device according to claim 1, wherein the correlation of the data is carried out according to rules and criteria defined in a second database, forming part of the on-board maintenance device.

3. The device according to claim 1, wherein the configuration data taken into account by the on-board maintenance device comprise:

a list of the systems of the aircraft and a historical record of updates of the systems of the aircraft.

4. The device according to claim 1, wherein the operational context data comprise physical parameters of the aircraft varying over the course of time:

geographical coordinates, altitudes, speeds, mass, aerodynamic configuration, quantity of fuel on-board, operational state of the on-board items of equipment, meteorological conditions.
