What is the minimum bulk fuel temperature allowable when using Jet A fuel?

• A. -20°
• B. -30°
• C. 0°
• D. -40°

Answer: (B)

The minimum bulk fuel temperature allowable when using Jet A fuel is -30°. This temperature is critical because Jet A fuel is a kerosene-based fuel that has a freezing point around this temperature. Maintaining the fuel at or above this temperature helps prevent the formation of ice and other contaminants that could block fuel lines or damage engine components. Operating at temperatures lower than -30° could lead to issues such as fuel crystallization, which can adversely affect engine performance and safety. Therefore, ensuring that Jet A fuel remains above this minimum temperature is essential for safe and efficient operations.
