What effect does ambient temperature have on fuel temperature requirements?

• A. Higher temperatures require lower fuel temperature.
• B. Fuel temperature must always exceed freezing point.
• C. Temperature does not affect fuel requirements.
• D. Fuel temperature must vary with altitude.

Answer: (B)

The selection that states fuel temperature must always exceed the freezing point is correct because it's crucial for ensuring proper fuel flow and preventing the formation of ice crystals in the fuel, which can occur at low temperatures. In aviation, fuel is typically required to remain a set number of degrees above its freezing point to avoid any potential blockages or fuel system failures during flight. When ambient temperatures drop, the risk of fuel freezing increases, so maintaining a temperature above the freezing point helps to ensure that the fuel remains effective and safe for engine operations. This requirement is particularly significant at higher altitudes, where temperatures often plummet. While altitude does impact fuel temperature along with ambient conditions, the primary rule is the necessity for fuel temperature to stay above freezing to ensure system reliability and safety during operations. Other options do not accurately reflect the principles governing fuel temperature management in aviation.
