Abstract: A port expansion device is connected to a user interface terminal in an aircraft. The user interface terminal displays a first selection page designed to make it possible to select a peripheral system from among a first set of peripheral systems connected to the user interface terminal, so as to transfer graphical interface control to the selected peripheral system. A second set of peripheral systems are connected to the user interface terminal via control circuitry of the port expansion device, which emulates peripheral system behaviour. The control circuitry exports a name representative of a menu navigation action on the user interface terminal, and emulates a second selection page in the style of the first selection page generated by the user interface terminal, making it possible to select a peripheral system from among the second set of peripheral systems. The port expansion is thus performed transparently.
