Describe the picture
Look at the photograph above and describe what you can see. Try to speak for about a minute, moving from a general overview of the scene, to the details, and finally to speculation about what is happening and why. Use the words in the box to help you. If you are not sure how to structure your answer, read our guide on how to describe a picture.

Now listen to the sample answer.
This photograph shows a twin-engine narrow-body airliner that has been pulled off the line for maintenance, parked over by the hangars rather than at a passenger gate. The left engine is the focus of the scene: its fan cowls and thrust-reverser cowlings have been hinged open, exposing the engine core and the dense tangle of pipes and wiring wrapped around the nacelle. A bright yellow access platform has been wheeled up against it, and three engineers in orange high-visibility vests and white hard hats are gathered on and around the steps, studying the powerplant; one of them appears to be working from a tablet, while a well-stocked tool trolley waits on the apron below. The aircraft wears a plain, unmarked white livery with a simple cheatline, and a maintenance hangar is visible in the background. I would imagine the crew reported a technical fault — perhaps an abnormal vibration or an engine warning on the flight deck — and that the engineers are now tracing it before deciding whether to rectify the defect on the spot or defer it under the MEL and release the aircraft back to service.
Answer the questions
- Where is the aircraft parked, and what about the state of the engine tells you this is not a normal turnaround?
- Now that the cowlings are open, what can you see of the engine’s internal components and the systems around it?
- What are the engineers doing on the platform, and what equipment are they using to investigate the problem?
- What do the plain livery and the surrounding apron suggest about whether this is scheduled or unscheduled work?
- What do you think caused the aircraft to be taken off the line, and what are the engineers’ likely next steps?
- It is parked on a maintenance apron over by the hangars rather than at a passenger gate, and one engine has been opened up with its cowlings swung back — clearly maintenance work rather than a routine turnaround between flights.
- With the fan cowls and thrust-reverser cowlings hinged open, you can see the engine core and the dense bundle of pipes, ducts and wiring that runs around the nacelle — the parts that are normally hidden behind the smooth outer casing.
- Three engineers in high-visibility vests and hard hats are inspecting the open engine from a yellow access platform; one is working from a tablet, probably reading fault data or a maintenance manual, and a tool trolley is positioned on the apron below.
- The plain, unmarked livery and the quiet maintenance area, away from the busy terminal, suggest this is unscheduled or unplanned work — the aircraft has most likely been pulled out of service to investigate a specific fault rather than for a routine check.
- Most probably the crew reported a technical problem, such as an abnormal vibration or an engine warning, and the engineers are now tracing the cause before deciding whether to rectify the defect there and then or defer it under the MEL and release the aircraft back into service.
| cowling | a removable or hinged panel that covers an aircraft engine; the engineers swing it open to reach the engine inside. |
| nacelle | the streamlined outer housing that surrounds an engine and holds it onto the wing or fuselage. |
| engine core | the central part of a jet engine — the compressor, combustion chamber and turbine — normally hidden behind the cowlings. |
| access platform | a wheeled set of steps and a working deck that engineers position beside an aircraft so they can safely reach high components. |
| high-visibility vest | a brightly coloured safety vest worn on the apron so staff are easy to see around moving aircraft and vehicles. |
| MEL (Minimum Equipment List) | an approved list that says which items may be temporarily inoperative, and under what conditions, while the aircraft is still allowed to fly. |
| powerplant | the engine and all the systems that make it run; another word for the aircraft’s engine as a whole. |
| to rectify a defect | to repair or put right a fault so that the system works correctly again and the aircraft is airworthy. |
Speaking practice
- Modern aircraft record huge amounts of fault and condition-monitoring data. How does this change the way engineers diagnose a problem compared with the past, and what are the limits of relying on it?
- There is often tension between keeping an aircraft on schedule and grounding it to investigate a fault. How should an airline balance commercial pressure against airworthiness and safety?
- What do you think attracts people to a career in aircraft maintenance engineering, and what qualities and responsibilities does the job demand?
Record yourself on a phone voice memo so you can play it back and self-review. Compare your description with the sample answer above — the goal is a clear, structured response that moves from an overview to the details and then to what you think is happening.
