Which part of the aircraft is identified by the white navigation light?

• A. The nose
• B. The left wingtip
• C. The tail
• D. The fuselage

Answer: (C)

Navigation lights are used to show an aircraft’s position and orientation at night. The red light sits on the left wingtip, the green light on the right wingtip, and the white light is mounted on the tail. Placing the white light at the tail gives other pilots a clear cue of the aircraft’s rear aspect, helping them gauge where you are and which way you’re moving when visibility is limited. So the white navigation light identifies the tail of the aircraft.
