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: 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.
