Which description matches the AVTUR color code?

• A. Has the word AVTUR in white letters on a blue background.
• B. Has the word AVTUR in white letters on a red background.
• C. Has the word AVTUR in white letters on a white background.
• D. Has the word AVTUR in white letters on a black background.

Answer: (D)

Signage color coding for fuel types is all about quick recognition and avoiding misfuelling. For AVTUR, the standard is white letters on a black background, which provides high contrast and legibility at a distance in various lighting conditions. This specific dark background with light lettering is what identifies aviation turbine fuel signage consistently across operations. The other color backgrounds would not match this established standard and would reduce readability or cause confusion with other fuel markings.
