What is the purpose of the fuel manifold system in large transport aircraft?

The purpose of the fuel manifold system in large transport aircraft is to manage fuel distribution from tanks. This system plays a critical role in ensuring that fuel is efficiently and effectively delivered to the engines from various fuel tanks throughout the aircraft. By regulating the flow of fuel, the manifold system helps maintain the balance of fuel within the aircraft, optimizes engine performance, and ensures that the engines receive a consistent and reliable fuel supply during different flight conditions and phases of operation.

This fuel distribution management is essential for maintaining the aircraft's weight balance, especially as fuel is consumed. It also aids in the prevention of fuel starvation to the engines and helps facilitate the transfer of fuel between tanks when necessary, contributing to the overall efficiency and safety of the flight operation.
