1. A method for a computer for assisting the maintenance of a complex system of an aircraft comprising a set of items, means for detecting faults of items or of functions implemented by items and means for establishing a first level of diagnostic, this method comprising the steps of:
obtaining an aircraft database, the content of said aircraft database corresponding to part of the content of a ground database comprising at least one entry associating a fault identifier with a list of items liable to be at the origin of the identified fault and a probability, for each item of the list of items, that the corresponding item is at the origin of said identified fault; detecting a fault; identifying a plurality of items of said set of items, each item of said plurality of items being liable to be at the origin of said detected fault, alone or in combination with at least one other item of said plurality of items; for each item of said plurality of items, determining a probability that the item considered is at the origin of said detected fault, said probability that the item considered is at the origin of said detected fault being determined on the basis of said aircraft database; identifying at least one item actually at the origin of said detected fault; and updating a temporary database on the basis of identifiers of said at least one identified item and said detected fault, said ground database being updated on the basis of the content of said temporary database, said steps of detecting a fault, identifying a plurality of items and of determining a probability being implemented in a system of an aircraft and the aircraft and temporary databases being stored in a system of said aircraft. |
