What is the main function of an aircraft’s fuel management system?

The main function of an aircraft's fuel management system is to monitor and control fuel levels for efficiency. This system ensures that the aircraft has adequate fuel for its flight while optimizing fuel consumption. It involves actively measuring the fuel quantity and distribution in the fuel tanks, providing real-time data to the flight crew regarding fuel status. This helps in making informed decisions about fuel usage to enhance efficiency, promote safety by ensuring sufficient fuel for the journey, and manage performance during various phases of flight.

Effective fuel management can also play a role in balancing the aircraft, which is crucial for maintaining stability and control across different flight conditions. While tracking the aircraft's altitude, providing navigation aids, and managing communications are important functions for the overall operation of the aircraft, they are not primary functions of the fuel management system. The focus of this system is specifically on ensuring the aircraft is supplied with the right amount of fuel and that fuel is being consumed efficiently throughout the flight.
