WING NAVIGATION LIGHTS
Dual forward navigation lights are installed in each wing tip. The wing-mounted
navigation lights are covered by wing tip lenses on both wings. Two green primary and
secondary navigation lights (position lights) are located in the right wing tip. Two red
primary and secondary navigation lights (position lights) are located in the left wing
tip. These lights are controlled by the NAV switch located on the EXTERNAL
LIGHTS panel.
When the NAV switch is selected, the primary lights on each wing illuminate.
Switchover from the primary to the secondary light system due to a navigation light
failure is achieved automatically, by means of a navigation light control/indication unit
(control box).
The primary wing navigation lights have a higher wattage than the secondary lights
and are protected from overheat due to insufficient cooling. Due to high temperature
conditions (limit temperature of the wing tip lens material) experienced on the ground,
the system will automatically switch to the secondary wing navigation lights. A
thermal switch is integrated in the equipment below each lens to detect temperature
changes for automatic switching to the backup (secondary) system.

TAIL NAVIGATION LIGHTS
Two white navigation lights (primary and secondary) are located at the aft extremity of
the airplane (fin and tail cone).
• Primary Light - One primary navigation light is located on the trailing edge at the
tail fairing. This light is controlled by the NAV switch located on the EXTERNAL
LIGHTS panel to control the wing navigation lights
• Secondary Light - One secondary navigation light is located in the tail cone and is
part of the combined rear strobe/navigation light unit. The bulb portion of the
combined rear strobe/ navigation light unit is the navigation light. The lower
portion of the unit is the strobe light. This navigation light is controlled by the
NAV switch (located on the EXTERNAL LIGHTS panel) which controls the wing
navigation lights
• When the NAV switch is selected the primary light will illuminate. Switchover
from the primary to the secondary light system due to a navigation light failure is
achieved automatically by means of the navigation light control/indication unit
STROBE LIGHTS
The anticollision light system consists of two redundant systems, one wing tip/tail
mounted and one fuselage mounted. One white anticollision strobe light is located on
each wing tip next to the navigation lights and one on the tail cone of the airplane.

WING/TIP TAIL MOUNTED STROBES
The wing strobe lights and the rear strobe light together comprise one system.
The flashing of the three white strobe lights is synchronized and simultaneous, and are
used as the main system on the airplane.
The lights are white in color and are controlled by the STROBE on/off switch located
on the EXTERNAL LIGHTS panel.

FUSELAGE-MOUNTED STROBES
The red/white anticollision strobe lights are located at the top and bottom of the
fuselage. The upper strobe light and the lower strobe light together comprise one
system. The flashing of the two lights is synchronized and simultaneous. These lights
can be selected white or red through a WHT/OFF/RED switch located on the
EXTERNAL LIGHTS panel. The red strobe light is incorporated in the fuselagemounted
lights for ground operational purposes to minimize unfavorable effects on the
crew and outside personnel during ground handling.
The fuselage mounted white anticollision system is used as a backup system on the
airplane.
