How are airport taxiway edge lights identifiable at night?

1. White omnidirectional lights

2. Blue omnidirectional lights

3. Green omnidirectional lights

4. Red omnidirectional lights

The correct answer is: Blue omnidirectional lights

Airport taxiway edge lights are identifiable at night by their blue omnidirectional illumination. This color is specifically used to delineate the edges of taxiways, providing pilots with a clear visual reference as they navigate on the ground. The use of blue lights minimizes confusion for pilots, especially in low visibility situations, and helps differentiate taxiways from runways, which are marked with a different color system. Understanding the color coding for airport lighting is crucial for safe ground operations. Taxiway lights illuminate the way for aircraft taxiing to and from runways, ensuring they remain on designated paths. This differentiation aids in preventing runway incursions and maintaining orderly ground traffic.
