What is a key function of the fuel management system in aircraft?

The fuel management system in an aircraft is crucial for ensuring the safe and efficient operation of the aircraft by managing fuel flow and maintaining the proper fuel level. This system monitors the amount of fuel in various tanks, coordinates the transfer of fuel between tanks as necessary to ensure proper balance and center of gravity, and regulates the flow of fuel to the engines to maintain optimal performance. By managing these aspects, the fuel management system helps prevent issues like fuel starvation or imbalance that could affect the aircraft's performance and safety.

In contrast, the other functions listed pertain to different systems within the aircraft. Monitoring altitude is managed by altimeters and the aircraft's avionics systems, while cabin pressure control is the responsibility of the environmental control system. Adjusting the speed of the aircraft is typically done via the throttles and autopilot systems. Each of these systems plays a distinct role, highlighting the specialized focus of the fuel management system on fuel-related functions.
