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 the NON ESS BUS.
Strobe Light
Anti-collision strobe lights are installed integral with the standard
navigation 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 the 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 firewall. 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 5-amp
RECOG LIGHTS circuit breaker on the NON ESS BUS.
