Lighting Systems
Lighting systems described in this chapter include:
Exterior Lighting
Exterior lighting consists of these lights:
Landing Lights
The landing lights consist of the left, right, and nose gear landing lights. The left
and right landing lights are located in the left and right wing root. These lights are
optimized for flare and ground roll. The two nose gear landing lights are optimized
for approach. The nose gear landing lights are inhibited when the nose landing
gear is not down and locked.
Runway Turnoff Lights
Runway turnoff lights are installed in the left and right wing roots. The lights
illuminate the area in front of the main gear.
Taxi Lights
Taxi lights are installed on the non–steerable portion of the nose strut. To add
lighting during ground roll, the two taxi lights are also illuminated when the nose
gear landing lights are selected ON. They are inoperative when the nose landing
gear is not down and locked.
