Minimum fuel / fuel emergency

오늘은 연료 용어의 결정판입니다. 두 표현을 정확히 구분하세요. MINIMUM FUEL은 "특정 공항에 착륙하기로 정했고 더 이상 지연은 못 받는다"는 알림(advisory). MAYDAY FUEL은 "이대로면 final reserve 아래로 착륙한다"는 비상(distress). 연료량을 비교해서 말하므로, 문법도 비교·정도(less than / enough to)로 갑니다.

1. Scenario

I was the First Officer of HL123, a twin-engine aircraft, holding near our destination because of weather.

While we were holding, our fuel kept decreasing, and we estimated that we could not accept much more delay. We still had more than our final reserve, but the margin was getting small.

At that point we declared MINIMUM FUEL to ATC. This is an advisory — it tells ATC that we are committed to landing at this airport and cannot accept any undue delay. It is not yet an emergency.

ATC understood and gave us priority for the approach, with no further holding. We calculated that we had enough fuel to land with our reserves intact. If the delay had continued and our fuel had dropped below the final reserve, we would have declared MAYDAY FUEL, which is an emergency.

In the end, we landed with our final reserve still on board.

2. 상황 한눈에 (At a glance)

English — Holding for weather, our fuel kept dropping and we could not accept much more delay. So we declared MINIMUM FUEL — an advisory that tells ATC we are committed to land here and cannot take any undue delay. It is not an emergency. If our usable fuel on landing would fall below the final reserve, then we would declare MAYDAY FUEL, which is an emergency and gives priority. We landed with our reserves intact.

한국어 — 기상으로 홀딩 중 연료가 계속 줄어 더 이상의 지연을 받을 수 없었습니다. 그래서 MINIMUM FUEL을 선언했어요 — 이 공항에 착륙하기로 정했고 부당한 지연은 못 받는다는 알림이지 비상은 아닙니다. 만약 착륙 시 사용 가능 연료가 final reserve 아래로 떨어진다면 그때 MAYDAY FUEL(비상)을 선언합니다. 우리는 예비 연료를 남긴 채 착륙했습니다.

9. Model Answer — Q1

"What happened to your aircraft? Explain the nature of the incident."

틀은 자유 — 무슨 일 → 어떻게 대처 → 결과 흐름이면 됩니다.

We were holding near our destination because of weather, and while we were holding our fuel kept decreasing. We still had more than our final reserve, but the margin was getting small, and we estimated that we could not accept much more delay.

At that point we declared MINIMUM FUEL to ATC. That is an advisory: it tells them we are committed to landing at this airport and cannot accept any undue delay. It is not an emergency yet, but it makes our situation clear.

ATC understood and gave us priority for the approach, with no further holding. We calculated that we had enough fuel to land with our reserves intact. If the delay had continued and our fuel had dropped below the final reserve, we would have declared MAYDAY FUEL, which is an emergency.

In the end, we landed with our final reserve still on board. The key was using the right term at the right time, so ATC knew exactly how urgent our fuel was.

10. Model Answer — Q2

"How do you think ATC handled the situation? Could it have been handled differently?"

Q2 = ATC 평가로 의견 표현을 익히는 자리. 아래는 한 예시 — 외워서 그대로 쓰지 말고, 시작·마무리 표현은 자유롭게 바꿔 보세요. (오늘은 살짝 비판이 섞인 톤도 연습)

To be honest, ATC handled it reasonably well, but I think they could have been a little more proactive. Once we declared MINIMUM FUEL, they gave us priority and stopped the holding, which was exactly what we needed.

The one thing I would change is the earlier holding. We were held for quite a while with no information about how long it would last, and that is what made our fuel tight. If they had given us an expected delay sooner, we could have made our decision earlier. Still, once we spoke up, their response was quick and helpful.

11. Follow-up Q&A

1. What is the difference between MINIMUM FUEL and MAYDAY FUEL? → MINIMUM FUEL is an advisory: we are committed to land here and cannot accept undue delay. MAYDAY FUEL is an emergency: our usable fuel on landing would be below the final reserve.
2. Is MINIMUM FUEL a request for priority? → Not directly. It is information for ATC. But it tells them we cannot take more delay, so they usually help.
3. When would you upgrade to MAYDAY FUEL? → As soon as I calculate that we will land with less than the final reserve, I declare MAYDAY FUEL to get an emergency priority.
4. How can you avoid this situation? → By asking for expected delays early, deciding to divert in good time, and watching the fuel margin during holding.
