Jet-A fuel characteristics include which of the following?

• A. A heavy kerosene base with a flash point around 120ºF and a freezing point around -40ºF.
• B. A gasoline-based fuel with high volatility.
• C. A heavy kerosene base, a flash point of 110-150ºF, a freezing point of -40ºF, and an energy content of 18,600 Btu per pound.
• D. A diesel-like fuel suitable for jet engines.

Answer: (C)

Jet-A is a kerosene-based fuel used in turbine engines, chosen for its good energy content and ability to stay liquid at very low temperatures. The important characteristics are a heavy kerosene base, a flash point that is higher than gasoline (typically around 110–150°F), a freezing point near -40°F, and an energy content about 18,600 BTU per pound. The description that includes all of these details, especially the explicit energy content value, best matches Jet-A.

The other statements either describe a gasoline-like fuel with high volatility or a diesel-like fuel, which is not correct for jet propulsion fuels, or omit the energy content data that helps distinguish Jet-A from other fuels.
