Abstract: The system includes additional display means including at least one additional screen and additional graphic interface handling means of the additional screen (able to display on the additional screen, a summary window depending on the operational state of the aircraft. The summary window comprises at least one first pictogram able to be displayed on a first display window of main display means of the aircraft without being displayed on the second window of the main display means, and at least one second pictogram intended to be displayed on the second display window of the main display means without being displayed on the first window of the main display means.

Abstract: This assembly (24) includes an emergency electricity generator (60). The electricity generator assembly (24) is controllable between an inactive rest configuration and an active configuration for producing energy in which the emergency electricity generator (60) delivers emergency electric energy to the electric network (20), without being electrically powered by the electric network (20). The emergency electric power generation assembly (24) is able to be placed in an intermediate standby configuration, in which the emergency electric power generation assembly (24) is electrically powered by the electric network (20) so that the emergency electricity generator (60) produces standby electric energy of lower power than the power delivered by the emergency electricity generator (60) in the active configuration.

Abstract: The device according to the invention comprises a holder and a transmitter supported by the holder, the transmitter being capable of transmitting an electromagnetic signal toward the surface any transmission frequency (Fe). It includes a receiver for receiving a signal reflected on the surface. The device comprises a guide assembly for guiding the movement of the holder to move the transmitter and the receiver across from the surface, tangentially relative to the surface. It comprises an extraction unit for extracting, in the signal received by the receiver, a shifted frequency component of the transmission frequency resulting from a local impedance variation of the surface. The extraction unit produces an extracted signal representative of the state of the surface from the shifted frequency component.

Abstract: The pipe (1) according to the invention includes: a fluid circulation hose (3), an outer protective tube (5), arranged around said hose (3) coaxially to said hose (3), and means (9) for centering said hose (3) in the outer protective tube (5). Said outer protective tube (5) comprises: at least one shell (21) in the form of a hollow tube having a transverse section larger than the transverse section of said hose (3), and forming an annular space (7) between said hollow tube and said hose (3) to receive said centering means (9), and an enclosure (23) that is wound on the outer surface of said shell (21), the enclosure (23) sealably surrounding the annular space (7).
