Name the five types of exterior lighting used on aircraft.

• A. Wingtip lights, flood lights, beacon lights, taxi lights.
• B. Position lights, strobe lights, navigation lights, beacon lights, and wing tip lights.
• C. Landing lights, taxi lights, runway edge lights, landing lights, and strobe lights.
• D. Position lights, anti-collision lights, landing lights, taxi lights, and wing inspection lights.

Answer: (D)

Exterior lighting on an aircraft is grouped to help others see the airplane, determine its orientation, and support operations on the ground and in the air. The five distinct exterior lighting types are:

Position lights (navigation lights) that indicate the aircraft’s location and direction: red on the left wingtip, green on the right, and white aft, helping other pilots judge orientation at night or in poor visibility.

Anti-collision lights that increase the aircraft’s conspicuity: typically bright strobe lights and beacons on the top and bottom of the fuselage, designed to alert nearby traffic.

Landing lights that provide forward illumination for takeoff and landing phases, also aiding other pilots and ground crew to see the aircraft on approach or during taxi in low light.

Taxi lights that illuminate taxiways and ramps on the ground, helping the crew maneuver safely while moving around the airport.

Wing inspection lights that illuminate the wings for preflight and in-flight inspection, aiding crew to spot ice, damage, or fuel leaks on the wing surfaces.

Other options mix in ground-based lights, redundant terms, or omit one or more of these standard categories, so they don’t align with the typical set of exterior aircraft lighting.
