Jet A-1 has a lower freezing point than Jet A, at which temperature?

• A. Lower freezing point (-47°C)
• B. Higher freezing point
• C. Higher sulfur content
• D. Lower volatility

Answer: (A)

Jet fuel freezing point is the temperature at which the fuel starts to solidify. Jet A-1 is formulated to stay liquid at much lower temperatures than Jet A, which is why it has a lower freezing point. The standard freezing point for Jet A-1 is -47°C, while Jet A solidifies around -40°C. This means Jet A-1 can operate in colder conditions without wax crystals causing solidification. The other options describe higher freezing points or unrelated fuel properties (sulfur content, volatility) and don’t specify the temperature at which Jet A-1 remains fluid.
