What is a basic fuel system designed to do?

A basic fuel system is primarily designed to take fuel out of the tank and deliver it to the engine. This function is essential for the operation of the aircraft, as the engine requires a consistent and reliable supply of fuel to operate efficiently. The system typically includes components such as fuel pumps, filters, and lines that ensure that fuel is drawn from the tank and transported to the engine where it can be mixed with air for combustion.

While the other options describe possible operations related to fuel systems, they do not accurately reflect the fundamental purpose of a basic fuel system. For example, recycling fuel back to the tank is a feature of systems designed for specific applications or advanced configurations but is not a characteristic of a basic fuel system. Measuring fuel consumption is typically managed separately through performance tracking systems rather than being a core function of the fuel system itself. Balancing fuel between left and right tanks is relevant for multi-tank setups, but again, it goes beyond the basic requirement of simply delivering fuel to the engine. Overall, the main role of a fuel system is to facilitate the flow of fuel necessary for engine operation.
