What is the minimum fuel requirement for a domestic operation?

• A. Origin → Destination + to the most distant alternate (if required) + 45 minutes at cruise
• B. 30 minutes reserve
• C. 15 minutes after landing
• D. Equal to total flight time

Answer: (A)

For a domestic operation, you must plan enough fuel to cover three parts: fuel to fly from the origin to the destination, fuel to reach the most distant alternate airport if an alternate is required, and a 45-minute reserve at normal cruising speed. The 45 minutes acts as a safety buffer for delays, holding patterns, or an unexpected diversion, ensuring you won’t run out before reaching a planned alternate or the destination. Even if no alternate is required, that 45-minute reserve is still required. Other options don’t meet the full planning needs: a 30-minute reserve doesn’t account for getting to the destination or an alternate, 15 minutes after landing is far too little for en route contingency, and equating fuel to total flight time ignores the necessary safety reserve.
