Autopilot failure in cruise

오늘은 고장 자체보다 업무 분담(CRM)과 워크로드 관리가 핵심입니다. 자동조종이 빠지면 한 명이 손으로 날고, 다른 한 명이 교신·항법을 맡죠. "한 명이 비행에 집중하도록"처럼 목적을 말하니, 문법도 목적(so that)으로 갑니다.

1. Scenario

I was the First Officer of HL123, a twin-engine aircraft, in the cruise.

During the cruise, the autopilot suddenly disconnected and would not re-engage. That meant we had to hand-fly the aircraft, which increases the workload, especially over a long sector.

To manage the higher workload, we divided the tasks clearly. The Captain hand-flew the aircraft, so that he could focus only on flying, and I took over the radio, the navigation, and the checklist.

We told ATC about the autopilot failure, and we requested a direct routing to reduce our workload. We also kept the cabin crew informed, in case we needed anything.

The systems were otherwise normal, so we continued to our destination and made a normal, manually flown approach and landing.

2. 상황 한눈에 (At a glance)

English — In the cruise, the autopilot disconnected and would not re-engage, so we had to hand-fly the aircraft. That raises the workload, so the key is good task-sharing: one pilot flies, the other handles the radio, navigation, and checklist. We told ATC, asked for a direct routing to reduce workload, and continued to a normal manual landing. On its own, this is manageable and not an emergency.

한국어 — 순항 중 자동조종이 풀려 다시 안 걸려, 손으로 비행해야 했습니다. 워크로드가 올라가므로 핵심은 분명한 업무 분담 — 한 명은 비행, 다른 한 명은 교신·항법·체크리스트. ATC에 알리고 워크로드를 줄이려 직항을 요청한 뒤, 정상적으로 수동 착륙까지 했습니다. 이것만으론 관리 가능하며 비상은 아닙니다.

9. Model Answer — Q1

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

틀은 자유 — 무슨 일 → 어떻게 대처 → 결과 흐름이면 됩니다.

During the cruise, the autopilot suddenly disconnected and would not re-engage. That meant we had to hand-fly the aircraft, which increases the workload, especially on a long sector.

To manage the higher workload, we divided the tasks clearly. The Captain hand-flew the aircraft, so that he could focus only on flying, and I took over the radio, the navigation, and the checklist.

We told ATC about the autopilot failure and asked for a direct routing to reduce our workload. We also kept the cabin crew informed, in case we needed anything from them.

The other systems were normal, so we continued to our destination and made a normal, manually flown approach and landing. On its own, an autopilot failure is manageable — the important part is sharing the workload well and not letting either pilot get overloaded.

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.

Overall, ATC supported us well. When we told them the autopilot had failed and asked for a direct routing, they gave us the shortcut quickly and kept their instructions simple, which really helped while we were hand-flying.

One thing that would help is keeping frequency changes to a minimum in a situation like this, since every extra task adds to the workload. But in our case they were clear and undemanding, and that made the flight much easier to manage.

11. Follow-up Q&A

1. Why is an autopilot failure a workload problem? → Hand-flying takes a lot of attention, so the flying pilot has less spare capacity, and the other pilot has to pick up the radio, navigation, and checklists.
2. How did you share the tasks? → The Captain flew the aircraft and focused only on flying, and I took over the radio, navigation, and the checklist.
3. Why did you ask for a direct routing? → A simpler route means fewer turns and less navigation work, so it reduces the overall workload.
4. Was this an emergency? → No. On its own it is manageable. It would become more serious if it happened with bad weather or another failure at the same time.
