What do location signs look like?

• A. Red letters on white background
• B. White letters on blue background
• C. Black letters on yellow background
• D. Yellow letters on black background

Answer: (D)

Location signs tell you exactly where you are on the airfield, which helps you taxi safely and stay in contact with ATC. They use a black background with yellow letters (often with a yellow border) because this high-contrast combo is easy to read quickly against the pavement in all lighting conditions. This color scheme is distinct from other field signs: mandatory signs are red with white letters, while information and direction signs use yellow backgrounds with black lettering. Recognizing the black-and-yellow look immediately tells you you’re at a location sign and your current position on the airfield.
