What does a red diagonal on AFTO 781A indicate?

• A. A discrepancy exists on equipment and is urgent
• B. A safety issue requiring immediate action
• C. A discrepancy exists on equipment but is not urgent
• D. Calibration overdue

Answer: (C)

The red diagonal on AFTO 781A signals that a discrepancy exists on the equipment but is not urgent. It flags a fault that needs corrective action, yet it doesn’t block flight or require immediate, emergency attention. Maintenance should schedule and complete the fix within the normal maintenance window, and document the action to close the discrepancy later. If the issue were truly urgent or a safety-of-flight item, it would be communicated with a more critical marker or notation that clearly calls for immediate action. Calibration overdue, on the other hand, would be indicated by a different status tied to the calibration due date, not simply a red diagonal.
