Abstract: The invention relates to a device for checking a plurality of indicator lights, wherein the intensity passing through each indicator light is sequentially measured and the measurements are compared with nominal intensities. The invention is more particularly applicable to the checking of the indicator lights of devices monitoring functional members.

Abstract: The present invention relates to a system for braking an aircraft taxiing on the ground. According to the invention, if an abnormality such as hydroplaning or bursting of a non-braked wheel is detected, the speed most representative of the real speed of the aircraft with respect to the ground is memorized. This memorized speed is regularly reduced to allow braking for the whole duration of the disturbance, avoiding locking or elimination of braking of the wheels of the main landing gear. The invention is more particularly applicable to the braking of wide-body aircraft.

Abstract: The invention relates to a device for automatically braking the wheel of a vehicle, in which a hydraulic brake controlled by a mechanical member is associated with the wheel and is controlled by an electrohydraulic servovalve receiving an electric signal for controlling a transmitter charged with converting the displacements of the mechanical member into electric signals, wherein, between the transmitter and the servovalve, the device comprises a switch which, for a first position, directly connects the transmitter and the servovalve and which, for a second position, connects the output of the transmitter to one of the inputs of a first adder whose output is connected to the servovalve, the other input of this first adder being connected to the output of an automatic braking signal generator. The invention is more particularly applied to the braking of aircraft.

Abstract: A braking system for an aircraft undercarriage with carbon disc brakes comprises apparatus responsive to the rotational speed of the wheels for regulating the rate of increase of braking pressure.
