What are the approved fuel types for the King Air 350?

The approved fuel types for the King Air 350 include Jet A and Jet A-1. These fuels are kerosene-based jet fuels that are widely used in turbine engines due to their properties that allow for efficient combustion and performance at high altitudes.

Jet A is the most common jet fuel used in the aviation industry, providing optimal performance characteristics such as low freezing points and high energy content. Jet A-1, while similar to Jet A, has a lower freezing point, making it suitable for operations in colder climates.

Using the correct fuel type is crucial for the safety and efficiency of the aircraft. It directly affects engine performance and operational reliability, ensuring that the aircraft functions within its design parameters.

In contrast, other fuel options listed do not meet the specifications required for the King Air 350's turbine engines. AvGas, which is primarily suitable for piston-engine aircraft, and Jet B, which is not approved for use in the King Air 350, do not provide the necessary performance characteristics for this aircraft's operational needs.
