What do runway centerline lights indicate until the last 3000 feet?

• A. Red/White
• B. Amber
• C. Green
• D. White

Answer: (D)

Runway centerline lights are designed to provide crucial visual guidance to pilots, especially during takeoff and landing. Until the last 3,000 feet of runway, these lights display white. This consistent white color assists pilots in maintaining proper alignment with the runway centerline and provides clear visibility of the runway's length and boundaries. As pilots approach the end of a runway, the color of the lights changes to indicate the remaining distance available for landing. This transition is essential for situational awareness, allowing them to make informed decisions about their approach. Therefore, the white lights in the initial portion of the runway serve as an important indicator for pilots, helping them navigate and assess their landing conditions effectively.
