What does "Clean and bright" indicate regarding aircraft fuel?

• A. Cloudy
• B. Hazy
• C. Contaminated
• D. Clean and bright

Answer: (D)

Interpreting fuel sample appearance: clean and bright means the fuel is visually free of contaminants. When you visually inspect an aviation fuel sample, a clear, bright look indicates no water, sediment, or haze is present, so the fuel meets the acceptable appearance standards for use. If the sample looks cloudy, hazy, or shows obvious contamination, that signals water or particulates are present and the fuel would require action before it’s used. In short, clean and bright is the sign of good visual quality for the fuel.
