What do yellow runway edge lights signify?

• A. The end of the runway is approaching
• B. The start of the runway
• C. The taxiway is closed
• D. The centerline is out

Answer: (A)

The main idea here is that color changes on runway edge lights give you a caution about the usable length of the runway. Runway edge lights are normally white along the usable pavement, but near the far end some systems switch to amber. That amber signals you’re approaching the end of the available runway, helping you judge remaining distance and avoid landing or taking off beyond the usable area. The start of the runway is indicated by threshold lights at the opposite end (not by yellow edge lights). Taxiway areas use blue edge lights, and a closed taxiway or a centerline issue would show different indicators, not yellow edge lights.
