What is the function of a fuel management computer in an aircraft?

The function of a fuel management computer in an aircraft is primarily to monitor, control, and optimize fuel flow and balance throughout the fuel system. This includes real-time tracking of fuel consumption, fuel distribution among the engines, and ensuring that all tanks maintain optimal fuel levels for safe and efficient operation.

By effectively managing the fuel flow, the computer can help prevent issues such as fuel starvation or uneven weight distribution, which could affect the aircraft's performance and handling. It also plays a critical role in enhancing fuel efficiency, which is vital for operational cost management.

The capabilities of a fuel management computer extend to providing data that assists the flight crew in making informed decisions about fuel usage and planning, contributing to overall safety and efficiency of flight operations. Therefore, option B accurately encapsulates the core functions of this system within an aircraft.
