What is the fuel threshold for FUEL LOW lights and red indicators?

• A. 250 pounds
• B. 100 pounds
• C. 500 pounds
• D. 50 pounds

Answer: (A)

Fuel management relies on warnings that give you time to plan as fuel runs down. The FUEL LOW lights and red indicators are tied to a set usable-fuel threshold. When the total usable fuel in all tanks drops to 250 pounds, the warning activates. This 250-pound mark provides a practical, safe margin for completing the approach, planning a diversion if needed, or going around, while still preserving an appropriate fuel reserve. Seeing the warning means you should start finalizing your approach and ensure you can reach a suitable landing with the remaining fuel. Other values would not align with a sensible warning timing for planning, so 250 pounds is the established threshold.
