Which type of fuel is generally used in the T-6B aircraft?

The T-6B aircraft primarily uses AVGAS 100LL as its fuel. AVGAS 100LL (AvGas 100 Low Lead) is a high-octane gasoline specifically formulated for use in aviation piston engines. The T-6B, which is a trainer aircraft with a piston engine, is designed to operate optimally on this type of fuel, which provides the necessary performance and efficiency required during training flights.

Using AVGAS 100LL helps in maintaining engine reliability and performance, which is crucial for flight operations, especially in a training environment where engine parameters must be predictable and stable. The lead component in the fuel also aids in preventing engine knock and improving overall combustion efficiency.

The other fuel types listed do not align with the T-6B's requirements. Jet A fuel is typically used in turbine engines, JP-4 is a mix used in military jet engines and is not suitable for piston engines, while MoGas is a type of automotive gasoline that generally does not meet the specific criteria laid out for aviation fuel. Therefore, AVGAS 100LL stands out as the appropriate and correct choice for the T-6B aircraft.
