What type of fuel does the C-5 APU utilize?

• A. Jet B fuel
• B. Jet A fuel
• C. AVgas
• D. Diesel fuel

Answer: (B)

The C-5 APU utilizes Jet A fuel, which is a standardized aviation fuel used for turbojet and turbofan engines. This type of fuel is kerosene-based, having a high flash point and lower volatility compared to other aviation fuels, making it safer and more suitable for use in high-performance aircraft like the C-5. Jet A fuel provides the necessary combustion characteristics to meet the operational demands of the APU, ensuring reliable power generation for ground support and system functioning when the main engines are not in operation. Moreover, the use of Jet A fuel is common across military and commercial aviation, as it is readily available at most airports, making it a practical choice for the C-5's auxiliary power requirements.
