What is the primary function of an aircraft's fuel system?

The primary function of an aircraft's fuel system is to store, manage, and deliver fuel to the engines. This entails several critical processes that ensure the engines receive the appropriate type and amount of fuel for efficient operation. The system is designed to maintain optimal fuel flow and pressure, thus supporting the aircraft’s performance and safety. Additionally, it often includes components such as fuel tanks, pumps, filters, and sensors, which work together to ensure that the engines operate smoothly throughout the flight. Proper management of the fuel system also involves monitoring fuel levels and determining fuel consumption to ensure that the aircraft can complete its mission safely and effectively. Each component of the fuel system plays a vital role in achieving these functions, making it a cornerstone of the aircraft's operation.
