What is the primary purpose of an aircraft fuel system?

The primary purpose of an aircraft fuel system is to store and deliver fuel to the engines. This system plays a crucial role in ensuring that the engines receive the correct type and amount of fuel necessary for optimal performance during various phases of flight. It encompasses several components, including fuel tanks, pumps, filters, and lines, all designed to transport fuel safely and efficiently from the storage tanks to the engines.

The fuel system also maintains proper fuel pressure and flow rate, which are vital for engine operation. Therefore, its design focuses on reliability and efficiency to support the overall safety and operational capability of the aircraft. Understanding this foundational function highlights the importance of proper fuel management and maintenance within aircraft operations.
