What must be done when fuel burn discrepancy exceeds 10%?

• A. Prepare a separate document and send to SOC
• B. Call dispatch immediately
• C. Both prepare a separate document and send to SOC, and call dispatch immediately
• D. Do nothing

Answer: (C)

When fuel burn is off by more than 10%, it signals a notable mismatch between what was planned and what’s actually happening. That kind of deviation isn’t just a data point; it affects safety, reserves, and the ability to land with adequate fuel. The right action is to escalate through both steps: prepare a separate fuel burn discrepancy document and send it to the System Operations Center, and also call dispatch immediately.

Documenting the discrepancy creates an auditable record that captures what was expected, what was observed, why the difference occurred (if known), and any corrective actions being considered. It ensures accountability and provides a reference for any investigation or regulatory review. Notifying the System Operations Center at the same time gets the formal, centralized oversight involved—SOC can review the flight plan, weather, load, and fuel needs, and guide the crew on re-planning, routing, or fuel reserves as necessary.

Calling dispatch right away brings operational coordination into play. Dispatch can coordinate with air traffic control, airports, and fueling services to update the flight plan, approve additional fuel if required, or arrange alternatives if the current plan no longer meets safety and regulatory requirements.

Doing just one part leaves gaps: without documentation you lose traceability; without informing dispatch you may miss timely operational support. Do both to ensure safety and proper handling of the abnormal fuel situation.
