What color lights indicate a taxiway?

1. White

2. Blue

3. Red

4. Amber

The correct answer is: Blue

Taxiway lights are specifically designed to guide pilots along taxiways safely and efficiently. The correct answer, indicating that blue lights represent taxiways, reflects the standardized color coding used in aviation. Blue lights are used exclusively for taxiways and help distinguish them from other types of lights on the airfield, such as runway lights, which are typically white or red, and provide important visual cues for pilots managing their ground movements. The use of blue lights enhances situational awareness, ensuring pilots can identify taxiway boundaries clearly, especially in low visibility conditions. Color differentiation is crucial in an airport environment to prevent confusion and maintain safe operations. Understanding this will aid pilots and ground personnel in navigating effectively on the airport surface.
