3. DESCRIPTION
A. Landing and taxi lights (Figures 1 and 4)
The landing and taxi lights are the elements of the sub-system which enable the pilot to see the landing runway and to direct the aircraft during taxiing. These lights are located into the leading edge of the L.H. wing. The illumination of the lights is controlled by switch-breakers, located on the front section of the central pedestal console.
Two green indicator lights (one for each function) located on M6 advisory panel, illuminate respectively when the switch-breakers are closed.
With light timer (Option)
A timer can be installed on L.H. wing tip in order to increase service life of landing and taxi lights. It allows a progressive energization. The timer is composed of a K203 relay and a R86 resistor for the taxi light, and a K204 relay and a R87 resistor for the landing light. The assembly is mounted on a support secured to N 12 rib.
