Stand guidance failure

도킹 유도장치(VDGS)가 한창 유도 중에 꺼지면? 답은 간단합니다 — 화면이 꺼지면 그 자리에 정지. 좁은 스탠드에서 "감으로 마저 들어가기"는 날개 값보다 비쌉니다. 오늘은 마샬러를 부르고 기다리는 이야기. 문법은 while(절)과 during(명사)의 구분입니다.

1. Scenario

I was the First Officer of HL123, taxiing onto our stand at the end of the flight, following the docking guidance system.

The display had us on the centreline, closing normally — and then, about halfway down the lead-in, it went blank. No azimuth, no closing distance, nothing. We stopped exactly where we were, set the parking brake, and kept the engines running, because we were not parked yet.

We told apron control: "HL123 on stand 24 — the docking guidance has failed halfway in. We've stopped and we're requesting a marshaller." They were honest about the wait: the marshallers were busy on another stand, about three minutes away. Apron also asked whether we could see the stop mark and finish the docking visually. We declined — on a tight stand, judging the last metres by eye from a cockpit that sits well ahead of the wheels is exactly what the guidance system exists to prevent. And because the adjacent aircraft looked close on the left, we asked for wing walkers as well.

While we waited, the cabin crew made a short announcement about the small delay. The marshaller arrived, took over with clear hand signals — come forward, slow, stop — with a wing walker on each side, and parked us on the mark.

We shut down about four minutes late. It later turned out the same display had failed once already that morning.

2. At a Glance

English — Halfway into the stand, the docking guidance display went blank. We stopped on the spot, kept the engines running, and requested a marshaller; apron offered "finish it visually" and we declined — tight stands and eyeball judgment do not mix, which is why the system exists. Marshallers were three minutes away on another job, so we waited, with wing walkers requested for the tight left side. The marshaller parked us with hand signals, four minutes late and undamaged. A blank screen is an instruction too — it says "stop."

한국어 — 스탠드 진입 중간에 도킹 유도 화면이 블랭크가 됐습니다. 우리는 그 자리에 정지하고, 아직 주기 전이라 엔진을 켠 채 마샬러를 요청했어요. 애프런이 "정지 마크 보이면 눈으로 마저 들어오겠냐" 제안했지만 거절 — 좁은 스탠드에서 눈대중은 유도장치가 존재하는 이유 그 자체니까요. 마샬러는 다른 스탠드 작업 중이라 3분 거리, 왼쪽 옆 기체가 가까워 윙워커도 요청했습니다. 마샬러가 또렷한 수신호로 마크에 세워 줬고, 4분 늦게·무손상으로 셧다운. 그날 아침 같은 화면이 이미 한 번 고장 났었다는 건 나중에 알았습니다. 꺼진 화면도 지시입니다 — "정지"라는.

9. Model Answer — Q1

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

틀은 자유 — 무슨 일 → 어떻게 대처 → 결과 흐름이면 됩니다.

At the end of the flight we were docking on our stand, following the guidance system — on the centreline, closing normally. About halfway down the lead-in, the display went blank: no azimuth, no distance, nothing.

We stopped exactly where we were, set the parking brake, and kept the engines running, since we were not parked yet. Then we told apron the guidance had failed and requested a marshaller. They offered us the option of finishing the docking visually, and we declined — on a tight stand, judging the last metres by eye from a cockpit that sits ahead of the wheels is exactly what the system is there to prevent. Because the aircraft on our left looked close, we asked for wing walkers as well.

The marshallers were busy on another stand, about three minutes away, so we waited. While we waited, the cabin crew made a short announcement about the delay. The marshaller then brought us in with clear hand signals, a wing walker on each side, and parked us on the mark.

We shut down four minutes late with nothing bent. A blank screen is an instruction too — it says "stop."

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.

Plain and simple, the apron team did their job well. The estimate was honest — three minutes, and it was three minutes — the wing walkers came without any argument, and when we turned down the "finish it visually" option, nobody argued the point. The marshalling itself was excellent: unhurried, standard signals, easy to read at that hour. Waiting never feels good with engines running, but a truthful wait beats an optimistic one.

The part I would question is the morning. The same display had already failed once earlier that day and had been put back in service without a fix. A recurring guidance fault on a tight stand should either take the stand out of service or pre-position a marshaller for every arrival until it is repaired — not wait for the next crew to find it blank at the worst possible moment. The response was clean; the earlier maintenance decision was not.

11. Follow-up Q&A

1. Why not finish the parking by eye if you can see the stop mark? → From the cockpit you sit metres ahead of your own wheels, and the wingtips are far behind you. On a tight stand, your eyes trick you about distance — that is why the guidance exists.
2. Why keep the engines running while you waited? → We were not parked or chocked. Shutting down mid-taxilane leaves the aircraft stuck; you shut down when you are on the mark with the brake set and chocks in.
3. Why ask for wing walkers as well as a marshaller? → The marshaller watches the nose and the mark; the wing walkers watch the tips he cannot see. On a tight stand they are one team.
4. What does it mean when the marshaller crosses his wands overhead? → Stop — immediately. It is the one signal every crew knows before any other.
