What are the two types of fuel that can be used in the T-6A?

The T-6A can utilize two specific types of fuel: Jet A and Jet A-1. Both fuels are kerosene-based and primarily used in aviation, particularly for turbine engines like the one in the T-6A. Jet A has a higher freezing point and is commonly available at airports, while Jet A-1 is an international specification of Jet A that has a lower freezing point, making it suitable for use in colder environments.

This choice is correct because it aligns with the operational guidelines established for the T-6A, which emphasizes the need for fuel compatibility with the engine's operational requirements. Other fuel types mentioned in the other options, including AvGas and Jet B, are not compatible with the T-6A engine or do not meet the necessary specifications. AvGas is typically used in piston-engine aircraft, while Jet B is less commonly used and has a different performance profile that does not meet the T-6A's needs. Therefore, using Jet A and Jet A-1 ensures optimal performance and safety during flight operations.
