A system for updating data for computer devices included in an aircraft, the computer devices being, when the data is updated, liable to affect or not the safety of an operator performing maintenance, the system is included in the aircraft and includes a data loading device, a communication device, a data router and a module for detecting at least one maintenance operation on the aircraft. The system includes: means, included in the communication device, for receiving a command for updating a computer device; means, included in the communication device, for controlling the data loading device and the data router in order to transfer the updating data to the computer device; and means, controlled by the module for detecting at least one maintenance operation on the aircraft, for blocking the updating if at least one signal indicating that a maintenance operation is being performed on the aircraft is received.

System and method for remotely updating data for computer devices included in an aircraft

A data updating system for computing devices included in an aircraft, wherein one computing device in a first group of computing devices is, and one other computing device in a second group of computing devices is not, when the data of the computing device is updated, liable to affect the safety of the operator carrying out the maintenance on the aircraft. The system includes a data loading device, a connection connecting the data loading device with the computing device in the second group, and a data router connected to the data loading device, the data router transferring updating data to the computing devices in the first group only when a command by an operator in the cockpit of the aircraft is detected.

System and method for updating data for computing devices included in an aircraft

A method and a device for managing software configurations of equipment of an aircraft, comprising a device for managing software configurations of equipment of the aircraft. The device for managing software configurations of equipment of the aircraft detects the availability of a communication link between a server on the ground and the aircraft, checks whether a configuration file is available and importing the configuration file, imports, from the server on the ground, one or more software updates identified in the configuration file and storage of the software update or updates in a temporary memory space; determines the instant as from which each update can be implemented, and demands the modification of the software configuration of the item or items of equipment with the software update or updates corresponding to the item or items of equipment.

Method and device for managing aircraft equipment software configurations

There is proposed a method of in-flight transmission of data recorded by a black box of an aircraft (), the method comprising the emission () by the aircraft () of a radioelectric beam (F, F) transporting said data according to a first directivity (D) if at least one predetermined parameter does not indicate a critical state of the aircraft (), and according to a second directivity (D) different from the first directivity (D) if the predetermined parameter indicates a critical state of the aircraft ().

Method of transmitting flight data recorded by a black box of an aircraft by a radioelectric beam whose directivity changes if a critical state of the aircraft is detected

The invention concerns a PCMCIA card for downloading flight data remotely via a wireless network to a ground station, the PCMCIA card being designed to be connected to an ACMS system of an aircraft, the ACMS system being designed to generate an ACMS report after at least one predefined condition has been satisfied, and to record flight data.
