On a precision runway, what happens at 2000 feet remaining in terms of lighting?

• A. Runway centerline lights begin to alternate white and red.
• B. Runway edge lights begin to change from white to yellow for the rest of the runway.
• C. Centerline lights turn red.
• D. Threshold lights begin to flash.

Answer: (B)

On a precision runway, lighting cues are used to signal how close you are to the end of the runway. The runway edge lights are white along most of the length, but in the final portion they switch to yellow. At 2,000 feet remaining, the edge lights begin to change from white to yellow for the rest of the runway. This amber color provides a clear cue that you’re in the last segment, helping you judge remaining distance and maintain situational awareness, especially in instrument flight and low visibility. The other options describe lighting changes that aren’t tied to the 2,000-foot boundary on a precision runway.
