What do yellow runway edge lights signify?

What do yellow runway edge lights signify?

• A. 2000 Feet of runway remaining, or half the runway if half the runway length is less than 2,000 feet
• B. End of runway
• C. Clear weather indicated
• D. 1000 feet remaining

Answer: (B)

The main idea here is how runway edge lighting communicates the usable length of the runway. Yellow runway edge lights indicate the boundary of the usable runway, signaling that you’re at or near the end of the surface intended for landing or takeoff. In other words, they mark the end of the usable runway area you should expect to use. So, seeing yellow edge lights tells you to treat the area as the end of the runway boundary rather than a regular, fully usable section. The other statements describe distances or weather, which aren’t conveyed by these lights.
