What does metering refer to in the context of aircraft fuel systems?

Metering in the context of aircraft fuel systems specifically refers to the management and control of fuel flow to the engine. It ensures that the correct amount of fuel is delivered to the carburetor or fuel injectors, which is crucial for engine performance. Proper metering allows for optimal combustion, maintaining the balance between fuel and air that the engine needs to function efficiently. This process helps to maintain engine efficiency and power output while minimizing the risk of engine failure due to fuel starvation or excess fuel flow. Thus, the focus on controlling the amount of fuel available to the carburetor robustly aligns with the purpose of metering in aircraft fuel systems.
