Listen to the audio and read the transcript in the task section below. The transcript contains 6 deliberate errors — words or phrases that do not match what you hear. Identify each error and write the correct version. Replay the audio as many times as you need, then check your answers against the answer key.
Before you listen — key vocabulary
These words appear in the recording. Knowing them before you listen will help you spot the errors accurately:
cargo door caution indication (noun phrase)
A warning signal on the flight deck that alerts the crew that a problem has been detected at one of the aircraft’s cargo hold doors.
non-normal checklist (noun phrase)
A step-by-step procedure that flight crews follow when something abnormal occurs on the aircraft.
Pan-Pan (phrase)
The international urgency signal, used when a serious problem exists that requires assistance but is not yet life-threatening.
door seal (noun phrase)
A rubber or composite gasket that forms an airtight join between a door and its frame to maintain cabin pressurisation.
Your dictation task
The transcript below contains 6 deliberate errors. Listen to the audio and correct each one.
Meridian 614, a Boeing 787, was cruising at flight level 350 on a flight from Dubai to London. Three hours after departure, the crew received a cargo door caution indication on the lower forward cargo hold.
Finding no evidence of rapid pressurisation, the crew followed the non-normal checklist and declared a Mayday with Vienna Centre. As a precaution, they requested a descent to flight level 300.
Vienna Centre approved the descent and coordinated a diversion to Vienna International Airport. The aircraft landed without further incident. A ground inspection found that a door latch had degraded, allowing a minor pressure differential across the cargo door frame. The aircraft was removed from service pending repair.
“Three hours after departure” → Five hours after departure
“rapid pressurisation” → rapid decompression
“declared a Mayday” → declared a Pan-Pan
“flight level 300” → flight level 250
“door latch” → door seal
Commonly missed:rapid decompression (both “decompression” and “pressurisation” sound plausible — this tests precise vocabulary retrieval); Pan-Pan vs Mayday (a critical phraseology distinction — Pan-Pan is correct here because no immediate life threat was confirmed at the time of declaration); flight level 250 (a number error that tests whether you caught the exact descent level).

A standard altitude measurement used in aviation above a certain height, based on a standard atmospheric pressure setting; flight level 350 equals approximately 35,000 feet.
cargo hold (noun phrase)
A section of the aircraft below the passenger cabin where luggage and freight are stored.
cargo door caution indication (noun phrase)
A warning signal on the flight deck alerting the crew that a problem has been detected at one of the aircraft’s cargo hold doors.
non-normal checklist (noun phrase)
A step-by-step reference that flight crews follow when something outside normal operations occurs.
rapid decompression (noun phrase)
A sudden, significant loss of cabin air pressure that requires immediate crew action; can be caused by structural damage, a faulty door seal, or a broken window.
Pan-Pan (phrase)
The international radio urgency signal; used when a serious situation exists but does not pose an immediate threat to life; one level below Mayday in the aviation emergency hierarchy.
pressure differential (noun phrase)
The difference in air pressure between two areas; in aviation, this refers to the gap between cabin pressure and the outside atmosphere at altitude, which keeps passengers safe when flying at high altitudes.
Speaking follow-up
You are the first officer on Meridian 614. After landing at Vienna, your company’s operations centre calls for a brief verbal update. Without referring to any notes, describe what happened, the actions your crew took, and the current status of the aircraft.
Record yourself on a phone voice memo so you can play it back and self-review. There’s no single right answer — the goal is to produce a clear, structured response under time pressure.
