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: System for braking a vehicle comprising an anti-skid device receiving speed data from a detector coupled to a non-braked wheel, wherein the system comprises a correction device comprising on the one hand first apparatus adapted to tramsmit to the anti-skid device the speed data each time that the variations of these data in time are lower than a deceleration threshold representative of the aquaplaning of the non-braked wheel, and, on the other hand, second apparatus adapted, each time that the variations of the velocity data are greater than the threshold, to transmit to the anti-skid device an estimated decreasing speed datum. The invention is more particularly applied to the braking of aircraft.
