Lighting Systems

Exterior Lighting

The airplane is equipped with wing tip navigation lights with integral
anti-collision strobe lights and recognition lights. The landing light is
located in the lower cowl.
Navigation Lights
The airplane is equipped with standard wing tip navigation lights. The
lights are controlled through the NAV light switch on the instrument panel
bolster.
28 VDC for navigation light operation is supplied through the 5-amp NAV
LIGHTS circuit breaker on NON ESS BUS.
Strobe Light
Anti-collision strobe lights are installed integral with the standard naviga-
tion lights. Each strobe is flashed by a separate power supply. The strobe
power supplies are controlled through the STROBE light switch on the
instrument panel bolster.
28 VDC for strobe light and control circuits is supplied through the 5-amp
STROBE LIGHTS circuit breaker on NON ESS BUS.
Landing Light
A High Intensity Discharge (HID) landing light is mounted in the lower
engine cowl. The landing light is controlled through the LAND light switch
on the instrument panel bolster.
Setting the LAND light switch 'on' energizes the landing light control relay
in the Master Control Unit (MCU) completing a 28 VDC circuit from the
airplane Main Distribution Bus 1 to the light's ballast located on the fire-
wall. The ballast provides boosted voltage to illuminate the HID lamp.
A 7.5-amp fuse on the Main Distribution Bus 1 in the MCU protects the
circuit.
Recognition Lights
The airplane is equipped with recognition lights on the leading edge of the
wing tips. The lights are controlled through the landing light switch on the
instrument panel bolster.
28 VDC for recognition light operation is supplied through the 15-amp
LANDING LIGHTS circuit breaker on Main Bus 3.
