Abstract:
1. A method for testing or evaluating a configuration of at least one equipment item in an aircraft, the aircraft including an on-board information system, the on-board information system including a secured part and a less secured part, the less secured part including a network interface configured to exchange data with an information system external to the aircraft, the secured part including a filtering module to filter the data received by the less secured part and including at least one first maintenance function, the method comprising: receiving within the information system of the aircraft at least one command to test or evaluate the configuration of the at least one equipment item via the network interface; encoding, in the less secured part, the at least one received command according to predetermined criteria to make the at least one received command compatible with the filtering module of the secured part when the at least one received command is intended for the secured part, and to make the at least one received command compatible with protocols of the less secured part when the at least one received command is intended for the less secured part; transmitting the encoded command intended for the secured part to the filtering module of the secured part of the information system of the aircraft; in response to reception of the transmitted encoded command, filtering within the filtering module of the secured part the at least one encoded test command to verify that the at least one encoded test command conforms to the predetermined criteria; and in response to the filtering, translating and executing the filtered encoded command in relation to the at least one first maintenance function.
