Abstract: A method for checking the compatibility of a complex installation which incorporates various electronic, electrical and mechanical units of apparatus including at least one computer when one of the units is substituted by another substantially equivalent unit. The method comprises: (a) recording identification codes for each of the units of apparatus comprising the installation, including the identification code of replacement devices so as to obtain a base of the new configuration of the installation; (b) recording in computer memory a reference base for the identification codes of the devices of the installation corresponding to the former configuration, and (c) comparing the reference base of the identification codes of the former configuration with the base of the identification codes of the new configuration so as to trigger an alarm when this comparison indicates a configuration change.

Abstract: This invention relates to a system for supplying fuel to an aircraft engine, wherein an electronic computer subdivides the stroke of the throttle lever into a plurality of zones, in each of which the thrust of the engine varies between a maximum value and a minimum value. The computer ensures a modulation of the thrust about the value corresponding to that displayed by the position of said throttle lever. No mechanical link is provided between the lever and the fuel admission valve.
