Abstract: A system for communicating between a commercial aircraft and the base of the airline that chartered the same when the aircraft is itself located on the ground during the flight preparation phases and before unloading the commercial freight or passengers. A method implements such a communication system by the commercial flight staff and/or the aircraft captain to prepare a flight and the commercial freight unloading phase.

Abstract: A method for the maintenance of an aircraft including an avionics system including a set of operating units. The avionics system is connected to a ground-based infrastructure via at least one communication medium. Maintenance data stored in the ground-based infrastructure and relating to the malfunction of at least one operating unit are obtained via the at least one communication medium, and at least one operating unit is repaired on the basis of the maintenance data obtained.

Abstract: An aircraft communication system including an aircraft terminal connected to at least one input/output unit. The system includes a portable resource connected to the aircraft terminal via a network connection. The at least one input/output unit is configured to interact with the unit formed by the aircraft terminal and the portable resource.

Abstract: A system enabling communication between an aircraft-based computer network and a ground-based computer network. The system establishes a network communication between a ground-based computer network and an aircraft-based computer network via at least one communication medium using a synchronous communication mode. The system can be used to simplify procedures involved in maintaining a fleet of aircraft connected to a maintenance control center (MCC) and, in particular, to facilitate and secure the updating of aircraft logbooks (e.g., a cabin logbook and technical logbook).

Abstract: A method for updating a software application stored in an equipment item on board an aircraft. The method comprises downloading update files to an on-board dataloader, checking the integrity and authenticity of the new software application version, transmitting this new software application version to the equipment item concerned, storing the new software application version in question into a standby memory zone of said equipment item, while this equipment item is still controlled by a previous version of said software application stored in an active memory zone, distinct from said standby memory zone, and finally, switching said standby and active memory zones, said equipment item being then controlled by the new software application version stored in the active memory zone after the memory zones have been switched.

Abstract: An aircraft including a network of computers on board the aircraft, software applications loaded onto the computers of the network of computers. This method includes interrogating the computers of the network of computers on board the aircraft to know the configuration of the software applications loaded into the computers of the network of computers on board the aircraft, analyzing the configuration by at least one computer, identifying the software applications for which there exists a more recent version than the version loaded onto the network of computers on board the aircraft, computing a new software configuration for the aircraft by a computer on the ground, constructing a set of software applications, integrating updated software applications corresponding to a more recent version of a software application loaded into the computers of the network of computers on board the aircraft, loading the new configuration onto the computers on board the aircraft.

Abstract: The invention relates to a method for the maintenance of an aircraft including an avionics system comprising a set of operating units. The invention is characterised in that the avionics system is connected to a ground-based infrastructure via at least one communication medium. The inventive method comprises: at least a step in which maintenance data stored in the ground-based infrastructure and relating to the malfunction of at least one operating unit are obtained via the at least one communication medium, and a step in which said at least one operating unit is repaired on the basis of the maintenance data obtained.

Abstract: A sandwich panel made of a composite material with acoustical attenuation for a wall and/or self-supporting covering, more particularly for doubling the bulkheads or cabin walls of aircraft, and including an alveolar structural core (14) especially a honeycomb core, and two skins (12, 16) disposed and rendered integral on both sides of the core, wherein the two skins (12, 16) include holes and wherein the holes of at least one of the two skins are micropores. A method for producing this panel is also disclosed.

Abstract: A reinforcing fiber of the non-oxide ceramic type or of carbon to be used in the manufacture of a composite material with a glass, glass-ceramic or ceramic matrix, which composite exhibits good oxidative stability, is treated using a process comprising the steps consisting of: if necessary, oxidizing the fiber superficially or depositing thereon a layer of the same composition but including oxygen; placing the fiber in a chemical vapor deposition vessel; carrying out a pre-treatment at a temperature of 850.degree. to 1250.degree. C., in the presence of hydrogen, at a pressure of 50 to 300 mbar; injecting a mixture of neutral carrier gas and ammonia; stopping the injection and adjusting the pressure to a value of 1 to 10 mbar; injecting AlCl.sub.3 in a neutral diluting gas; producing on the fiber a deposit of AlN by simultaneously injecting a mixture of AlCl.sub.3 and a neutral carrier gas, and a mixture of NH.sub.

Abstract: Carbonaceous material according to the invention is protected against oxidation by boron carbonitride, which is infiltrated (4) or deposited in layer form (8) and which contains in atomic %;1 to 98% carbon,1 to 98% boron and1 to 98% nitrogen.

Abstract: This composite material with a fibrous reinforcement has refractory fibres (2) embedded in a nonmetallic matrix (4) and an interphase material (6) interposed between the fibres and the matrix, the interphase material being boron carbonitride with a lamellar or amorphous structure containing in atomic %, 0 to 98% nitrogen, 1 to 99% carbon and 1 to 99% boron. The composition of the interphase material can be homogeneous or vary gradually from the fibre-material interface (8) to the material-matrix interface (10).
