Abstract: Configuring an on-board maintenance information system in an aircraft, the information system comprising a first communication interface and a second communication interface, a protected domain, an open domain, a first maintenance application module of the protected domain, a second maintenance application module of the open domain, a first data filtering module, and a second data filtering module. After having determined a mode of connection for a mobile maintenance terminal to the information system, the second data filtering module is configured to filter data exchanged between the first communication interface and the maintenance application module of the open domain if the terminal is directly connected to the information system via the second interface.

Abstract: A method and device for accessing maintenance functions of an aircraft from a mobile maintenance terminal. First, the situation of the aircraft is determined. Then, if this situation allows a mobile maintenance terminal to access a maintenance information system on the ground and the information system of the aircraft, a connection is established between the mobile maintenance terminal and the maintenance information system on the ground and at least one maintenance command intended for the information system of the aircraft is transmitted to the maintenance information system on the ground. If this situation allows the mobile maintenance terminal to access only the information system of the aircraft, a connection is established between the mobile maintenance terminal and the information system of the aircraft and at least one maintenance command is transmitted to the information system of the aircraft.

Abstract: A method for testing or evaluating the configuration of at least one equipment item in an aircraft includes receiving at least one command to test or evaluate the configuration of the at least one equipment item via a network interface of a less secure part of an on-board information system of the aircraft. The network interface is capable of exchanging data with an information system external to the aircraft. The method also includes encoding the at least one received command and transmitting the encoded command to the secured part of the information system of the aircraft. In response to reception of the encoded command, the at least one encoded test command is filtered. In response to the filtering, the encoded command is translated and executed in relation to at least one first maintenance function of the secured part.

Abstract: A method executes at least one instruction in an on-board maintenance device from a remote system connected to the maintenance device via a communication network. The method includes receiving at least one datum representative of at least one command having a correspondence with the at least one instruction. The method also includes filtering the at least one received datum. In response to the filtering, if the at least one received datum represents a valid command, the method includes converting the at least one received datum to identify the at least one instruction.

Abstract: The invention in particular has as an object the configuring of an on-board maintenance information system in an aircraft, the information system comprising a first (285) and a second (250) communication interface, a protected domain (240) and an open domain (245), each of the domains comprising maintenance functions (260, 275), and a data filtering module (255, 270). After having determined a mode for connection of a mobile maintenance terminal to the information system, the filtering module is configured to filter the data exchanged between the second interface and a maintenance function of the open domain if the terminal is directly connected to the information system via the first interface. If the terminal is connected to the information system via an information system on the ground and via the second interface, the filtering module is configured to filter the data exchanged between maintenance functions of the protected and open domains.

Abstract: The invention in particular has as an object to access maintenance functions of an aircraft from a mobile maintenance terminal. First of all, the situation of the aircraft is determined (705). Then, if this situation allows a mobile maintenance terminal to access a maintenance information system on the ground and the information system of the aircraft, a connection is established (710) between the mobile maintenance terminal and the maintenance information system on the ground and at least one maintenance command intended for the information system of the aircraft is transmitted (730) to the said maintenance information system on the ground. If this situation allows the mobile maintenance terminal to access only the information system of the aircraft, a connection is established (740) between the mobile maintenance terminal and the information system of the aircraft and at least one maintenance command is transmitted (755) to the said information system of the aircraft.

Abstract: An aircraft wireless network in an aircraft includes a maintenance server, a cabin server, a radio switch, a network switch, and a cabin access point. The network switch and radio switch are configured to arrange the aircraft wireless network according to at least two distinct configurations. In a first configuration the cabin server is permitted to connect to the at least one cabin access point by the network switch and a first aircraft access point is connected to the external antenna by the radio switch. In a second configuration the maintenance server is permitted to connect to the at least one cabin access point by the network switch and a second aircraft access point is connected to the external antenna by the radio switch. In the first and second configurations the maintenance and cabin servers are prohibited from simultaneously connecting to the at least one cabin access point.

Abstract: The object of the invention is a method and a device for testing or evaluating the configuration of an equipment item in an aircraft comprising an on-board information system having a highly secured part and a less secured part, the less secured part comprising a network interface capable of exchanging data with an external information system, the secured part comprising a maintenance function. After at least one command to test or evaluate the configuration of the equipment item has been received (400) via the said network interface, the received command is encoded (410) then transmitted (415) to the secured part of the information system of the aircraft. In response to the reception of the encoded command, this is filtered (420). In response to the filtering step, the encoded command is translated and executed (425) in relation to the maintenance function.

Abstract: The object of the invention is a switching device in an aircraft wireless network for configuring the network from a maintenance configuration to a commercial use wherein the passengers have access to the network. The aircraft comprises a maintenance server and a cabin server as well as a cabin access point connected to an internal antenna and an outside access point connected preferably to two external antennas. The network infrastructure additionally comprises a network switch, a radio switch and a maintenance access point. In a first configuration, the cabin server is connected to the cabin access point and the outside access point is connected to the two external antennas. In a second configuration, the maintenance server is connected to the cabin access point and the maintenance access point is connected to one of the two external antennas.

Abstract: The object of the invention is a secure command method and device for controlling an on-board maintenance device, such as a maintenance device installed on board an aircraft, from a remote maintenance terminal. The maintenance device is connected to the remote maintenance terminal by a communication network. After at least one datum representative of at least one command associated with at least one instruction has been received, the received datum is filtered to determine the validity of the command. If the received datum is valid, an instruction or a set of instructions associated with the command represented by this datum is identified in order to be executed. The filtering step is preferably iterative and based on the transmission protocol as well as on the encoding of the datum.
