How is 'minimum fuel' defined?

• A. When you will land with less than 60 minutes of fuel
• B. When the crew can accept no undue delay
• C. When fuel equals 15% of capacity
• D. When you can land within 5 minutes of arrival

Answer: (B)

Minimum fuel means you have to land as soon as practicable and cannot accept any undue delay. It’s a flag to ATC that, while there isn’t an immediate emergency, fuel is tight enough that you must proceed to landing promptly and won’t tolerate holding or avoidable delays. The other options rely on fixed numbers or timing, which don’t define this state—the idea is the obligation to land as soon as possible due to fuel constraints.
