LIGHTING SYSTEM
EXTERNAL LIGHTING
I The airplane is equipped with three navigation lights, two retractable
landing lights (right light is optional), an optional taxi light, two anti-
collision lights and two optional wing deice lights.
Navigation Lights
The navigation lights are located in the tailcone stinger and in each
wing tip assembly. These lights are energized with the navigation lights
switch breaker on the left side console, see Figure 7-18. Proper operation
can be checked by observing reflections on the ground below the tail light
and from objects surrounding the airplane to ensure the lights are illumi-
nated.
Landing Lights
The retractable landing lights (right light is optional) are located in
the lower
surface of the wing tips. These lights are extended, retracted
and illuminated by the landing light switch breaker on the side console,
see Figure 7-18. With the switch positioned to LOG, the landing 1 ights
wi 11 extend and ill urni na te. In the off (center) position, the 1i ghts wi 11
remain extended but will not illuminate. In the RETRACT position, the
lights will retract flush with the respective wing tip.
Taxi Light
The optional taxi light, attached to the nose gear, provides adequate
illum,ination
for night taxiing. The taxi light is controlled by the taxi
1 ight switch breaker on the side console. see Figure 7-18.
Anti-Collision Lights
The anti-collision lights, with individual power supplies, are located
adjacent to each wing navigation 1 ight. These 1 ights are actuated by the
anti-collision light switch breaker on the left side console, see Figure
7-18.
~--------NOTE:----------.
Do not operate the anti-collision lights in condi-
tions of fog, clouds or haze as the reflection of
the light beam can cause disorientation or vertigo.
Wing Deice Lights
The optional wing deice lights are installed in the outboard side of
each engine nacelle and illuminate the outboard wing leading edge deice
boots. The lights allow the pilot to check for ice accumulation on the
wing leading edges. The lights are actuated by the deice light switch
breaker on the side console, see Figure 7-18.
All exterior lighting should be checked for proper operation before
night flying. Cockpit recognition of operational exterior lighting can be
determined by looking for ground illumination by the various lights.
