Which light indicates a malfunction when the automatic fuel management system is off schedule?

The light that indicates a malfunction when the automatic fuel management system is off schedule is associated with the indication of the system's status. In the context of aircraft systems, particularly on the C-17, the SCHD light alerts the crew to situations where the fuel management system is not functioning in its intended manner or is not properly synchronizing the fuel flow. This is crucial for maintaining the aircraft's balance and performance during flight.

When the SCHD light illuminates, it signals that there is an inconsistency in the aircraft's fuel management, which could affect overall operational efficiency and safety. This status indicates either a malfunction or an operational anomaly that requires the pilot's attention, informing them that they might need to manually adjust or monitor the fuel systems to ensure safe flight operations.
