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.

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.

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.
