In the last 1000 feet of runway remaining, runway centerlights are which color?

• A. White
• B. Alternating red/white
• C. Red
• D. Blue

Answer: (C)

Runway centerline lighting uses color changes to give you distance-to-end cues. White lights run along most of the runway, helping you stay centered. As you approach the far end, the pattern shifts: the centerline lights become alternating red and white in the final portion, and in the last 1,000 feet they are red only. That solid red in the final segment clearly marks the runway end, signaling you are within 1,000 feet of the end. So the color in the last 1,000 feet is red.
