What does the inboard tank fuel scheduling system do?

The inboard tank fuel scheduling system is designed to ensure proper fuel distribution within the aircraft's fuel system. It specifically functions to move fuel from the aft compartment to the forward feed box in the inboard tanks. This movement is crucial for maintaining the correct fuel balance and ensuring that the engines receive a consistent supply of fuel, which is necessary for optimal performance and safety during flight. By actively managing fuel levels and distribution, the system helps prevent fuel starvation during critical phases of flight and contributes to overall aircraft stability and efficiency.

The other options reference manual operations or fuel movements that do not align with the primary function of the inboard tank fuel scheduling system, particularly concerning the different tank compartments.
