The exam has one job: to check that you can speak and understand English clearly in real aviation situations — especially when something unexpected happens. It is not a test of grammar rules or of your technical knowledge. It is a test of communication.
The shape of it
Speaking and listening only — no reading test, no writing test.
About 25–30 minutes, face to face with an examiner (or by phone/computer).
Three parts: an interview about your work → listening and responding to real radio situations → describing a picture and discussing an aviation topic.
You are graded from Level 1 to Level 6. Level 4 (“Operational”) is the pass. Level 4 accepts an accent and the occasional slip — what matters is that a listener understands you without effort.
The six things the examiner listens for
Pronunciation Your accent is fine — but words must be clear enough that a stranger never has to guess.
Structure Sentences that hold together, with the right tenses when you describe what happened and what will happen.
Vocabulary Enough words for the job — and the skill to work around a word you don't know.
Fluency Speaking at a natural pace without long, frightened pauses.
Comprehension Understanding what you hear — including voices and accents you are not used to.
Interactions Reacting quickly and correctly: answering, checking, clarifying — not going silent.
The single biggest score-changer: what you do when you don't understand or can't find a word. Silence loses marks. Checking, guessing out loud and explaining another way gains them. Everything in this lesson builds that habit.
Warm up — say it out loud (60 seconds)
In your own words: what is your job, and why does clear English matter in it? Speak until the timer runs out — don't stop to correct yourself.

Numbers & letters — where clarity is safety
More misunderstandings happen over numbers than anything else. In aviation, numbers are said digit by digit, and a few are pronounced differently on purpose, so they cannot be confused.
The aviation numbers — say each digit:
0 ZE-RO · 1 WUN · 2 TOO · 3 TREE · 4 FOW-er · 5 FIFE · 6 SIX · 7 SEV-en · 8 AIT · 9 NIN-er · decimal DAY-SEE-MAL · hundred, thousand
The dangerous pair: -teen vs -ty.Thirteen and thirty, fourteen and forty, fifteen and fifty sound almost the same to a tired listener. The fix is stress: thir·TEEN (stress the end) vs THIR·ty (stress the start). Say both, slowly, three times each.
Read-back drill
Read these aloud the aviation way — digit by digit — then say what each one is:
Wind two-three-zero degrees, one-five knots, gusting two-seven. Visibility four thousand metres. QNH one-zero-one-eight. Temperature one-three, dew point one-zero.
Say: “Wind two-three-zero degrees” (230°), “one-five knots” (15 kt), “gusting two-seven” (27 kt). “Visibility four thousand metres.” “QNH one-zero-one-eight” (never “one thousand and eighteen”). “Temperature one-three, dew point one-zero.”
A pilot needs the wind. Which read-back is clearest and correct?

Spell it
Spell these aloud using the alphabet: an airport code such as EGLL (London Heathrow), then the words “FOG” and “GUST”.
Pronunciation focus. In many languages, words rarely end in a hard consonant, so it is easy to add a small vowel — “win-da”, “fog-a”. On the radio that costs clarity. Practise stopping cleanly: wind. fog. gust. knots. front. No vowel on the end.
The words of your world
These are everyday ideas for anyone who works with the weather. Here they are in the English an examiner — and a pilot — expects. Tap each card to reveal the meaning.
visibilityHow far you can see. “Visibility is reducing.”
gustingWind rising sharply for a moment. “Fifteen knots, gusting twenty-seven.”
overcastThe whole sky covered in cloud.
scattered / brokenCloud covering part of the sky — scattered is less, broken is more.
cumulonimbus (CB)The tall storm cloud — thunder, heavy rain, danger to aircraft.
the ceilingThe height of the lowest broken or overcast cloud.
QNHThe pressure setting for the altimeter, in hectopascals.
wind shearA sudden change in wind — very dangerous on approach.
to veer / to backThe wind turning clockwise (veer) or anticlockwise (back).
deterioratingGetting worse. The opposite is “improving.”
a frontThe edge of a moving air mass that brings a change of weather.
RVRRunway visual range — how far a pilot can see along the runway.
Read the weather report
This is a METAR — a routine weather report. Read it aloud, then say what it means in normal spoken English, as if you were briefing a pilot.
One good way to say it: “At eleven fifty: wind three-two-zero degrees, one-two knots. Visibility ten kilometres or more. A few clouds at two thousand five hundred feet, scattered at four thousand. Temperature two-four, dew point one-seven. QNH one-zero-one-eight. No significant change expected.”
In that report, what does 9999 mean?
Now without the reveal
Read this one aloud and brief it in plain English — there is a change coming, so mind your tenses:
Roughly: “Wind one-eight-zero degrees, one-five knots, gusting two-eight. Visibility four thousand metres in rain showers. Cloud broken at one thousand two hundred feet, and a few cumulonimbus at two thousand. Temperature two-two, dew point one-nine. QNH one-zero-one-three. Temporarily, visibility will drop to two thousand metres in a thunderstorm with rain.” Notice: is dropping / will drop / it's deteriorating.
Part 1 — talking about your work
The exam opens with a friendly interview about you and your job. It looks easy, so people relax and speak in three-word answers — and lose marks. The goal here is full, flowing answers: say what, then why, then an example.
The what → why → example habit. “I check the visibility (what), because a pilot needs it to decide whether to land (why) — last winter we had fog drop below minimums in ten minutes, and I had to update the report straight away (example).”
1. Tell me about your job. What does a weather observer actually do in a shift?
01:30
2. Walk me through how you make a single weather observation, step by step.
01:30
3. What is the most difficult weather you deal with at your airport — and why is it difficult?
01:30
4. Why does accurate weather information matter for safety? Convince me.
Reach for these: “My main responsibility is to…” · “What that means in practice is…” · “For example, on one occasion…” · “If the information is wrong, the risk is that…” · “That's exactly why…”
Part 2 — when things go wrong
This is the heart of the test, and where Level 4 is won or lost. You hear a non-routine situation and you must react: describe what is happening, warn, advise, and — if you don't understand — check, don't freeze.
Three moves that always earn marks:
Paraphrase when a word won't come: not sure of “hailstones”? — “small balls of ice falling from the cloud.”
Clarify when you're unsure: “Say again the visibility, please” · “Confirm you mean…”
You are on shift. In fifteen minutes, the visibility has fallen from eight kilometres to four hundred metres. Sea fog is rolling in fast. Describe what is happening to the tower and say what they should expect. Speak for one minute.
01:00
Something like: “Tower, be advised the visibility is deteriorating rapidly. In the last fifteen minutes it has dropped from eight kilometres to four hundred metres in sea fog moving in from the coast. It is still falling. I'd expect it to go below landing minimums very soon — you should be prepared for diversions. I'll issue a special report now and keep you updated.”
Situation 2 — the storm
A line of cumulonimbus is building to the south and moving towards the field. Warn the tower: what is coming, how soon, and what it will bring.
01:00
Something like: “Tower, there's a line of cumulonimbus building to the south and moving this way. I estimate it will reach the field within thirty to forty minutes. Expect thunderstorms, heavy rain, a sharp drop in visibility and strong, gusting winds — and there is a real risk of wind shear on the approach. I'd recommend warning inbound traffic now.”
Situation 3 — the misunderstanding
A pilot with limited English reads back your visibility as “one thousand four hundred” when you said “four hundred.” This is dangerous. Correct him clearly — slowly, simply, and make sure he has understood.
00:45
Something like: “Negative, negative. The visibility is four hundred metres — four, zero, zero. Not one thousand four hundred. Four hundred metres. Please read back the visibility.” (Slow, repeat, break the number into digits, ask for a read-back.)
You didn't catch what the pilot said. What earns the most marks?
Part 3 — describe & discuss
You are shown a picture and asked to describe it, then to discuss a wider aviation topic. Describe in a clear order — general first, then detail, then what it means — and never stop at one sentence.
Describe this picture (about 90 seconds)
Start wide (“This is an airfield in bad weather…”), then the detail (the storm, the rain, the windsock, the aircraft, the light breaking through), then what it means for flying.
01:30
Useful words: in the foreground / in the background / on the left / storm clouds building / a bolt of lightning / heavy rain / the windsock is stretched out, so the wind is strong / an aircraft on final approach / the sky is clearing on the right / conditions look marginal for landing.
Then discuss
Choose one and speak for two minutes:
Is weather the biggest cause of flight delays? What else competes with it?
Machines now record much of the weather automatically. Is there still a need for a human observer? Argue your case.
Is the weather at airports becoming harder to predict? What have you noticed yourself?
02:00
Mock test — the three parts, back to back
Run it like the real thing: no notes, no stopping. Start each timer and speak until it ends.
Part 1 · Interview
“Tell me about a normal working day for you, from the start of your shift.”
01:30
Part 2 · Non-routine
“A strong, gusting crosswind has come up on the active runway just as several aircraft are inbound. Describe the situation to the tower and say what they should do.”
01:00
Something like: “Tower, be advised the wind has increased and veered — it's now almost across runway three-zero, two-four-zero degrees at twenty knots, gusting thirty-five. That's a significant crosswind, close to the limit for some types. I'd recommend warning inbound traffic and considering a runway change. Expect possible go-arounds.”
Part 3 · Discuss
“How could better weather information make flying safer in the future?”
02:00
Before you finish — be honest with yourself
I said every number digit by digit, and kept thirteen and thirty apart.
When I lost a word, I explained it another way instead of stopping.
When I wasn't sure, I said “Say again” instead of guessing.
My sentences kept going — what, why, and an example.
I finished my consonants: wind, fog, gust — no extra vowel.
Any box you couldn't tick is your target for next time. That is exactly what the examiner is scoring — and exactly what keeps a pilot safe.
