What are the four types of fuel pumps found in the T-1?

The four types of fuel pumps found in the T-1 are Boost, Jet, Transfer, and Engine Driven. Each of these fuel pump types plays a specific role in the aircraft's fuel system.

The boost pump is designed to pressurize the fuel system and ensure that fuel is readily available to the engine-driven pumps, particularly during starting and low power situations. The transfer pump is responsible for moving fuel between the fuel tanks to maintain balance and optimize fuel usage. The engine-driven pump, often referred to as the primary fuel pump, operates when the engines are running and maintains fuel flow to the engines at the necessary pressures for optimal performance.

The mention of 'Jet' within this context may refer to a particular function or type of fuel management that ties back to how fuel is directed to the engines but is not a standard term for a type of pump in aviation fuel systems.

Incorporating additional types such as Fuel Control or Electric pumps does not accurately reflect the configuration of the T-1's fuel system. Thus, the classification presented in the correct response embodies the essential components of the fuel system relevant to the operation and efficiency of the aircraft. Understanding these components is crucial for ensuring safe and efficient flight operations.
