This ICAO Level 4 vocabulary list focuses on concrete words you can use to describe movements, weather and problems. Learn each term with its short example; then describe the same situation in your own words.
A useful word is one you can retrieve when a conversation changes. If a technical term is missing, describe what you see, where it is and what you need. The ICAO language rating also considers Pronunciation, Structure, Fluency, Comprehension and Interactions.
Listen to a term and try to explain it before revealing the card.
Look at each picture where shown and choose the best answer.
Say a short new sentence using any words you missed.

PRACTICE 01
Ground and communication
Listen to the term, recall its meaning and reveal an example.
Apron
The area where aircraft park and receive ground services. Example: The aircraft is parked on the apron.
Stand
A designated aircraft parking position. Example: We are waiting at the stand.
Taxiway
A route used by aircraft moving on the ground. Example: A vehicle is on the taxiway.
Runway
A prepared surface used for take-off and landing. Example: There are birds on the runway.
Holding point
A marked place where an aircraft may have to wait before entering a runway. Example: We are at the holding point.
Pushback
Moving an aircraft backwards from its stand, usually with a tug. Example: We are ready for pushback.
Tug
A vehicle used to move an aircraft on the ground. Example: The tug is connected to the nose gear.
Clearance
Permission or an instruction from air traffic control for a specified action. Example: The crew reads back the clearance.
Readback
A spoken repetition of a received instruction or clearance. Example: The controller checks the readback.
Traffic
Aircraft or other relevant movement in the operational area. Example: We have the traffic in sight.
PRACTICE 02
Flight and visibility
Listen to the term, recall its meaning and reveal an example.
Heading
The direction in which an aircraft is pointing. Example: We are turning to the assigned heading.
Altitude
A vertical distance measured from mean sea level. Example: The controller gives an altitude.
Flight level
A level expressed using the standard pressure reference. Example: The crew maintains the assigned flight level.
Climb
To gain height. Example: We are climbing to the assigned level.
Descend
To lose height. Example: We are descending as cleared.
Maintain
To keep a specified condition, such as a level or heading. Example: Maintain the assigned heading.
Approach
The phase of flight in which an aircraft prepares to land. Example: The crew briefs the approach.
Departure
The phase of leaving an airport. Example: The departure is delayed by weather.
Visibility
How far it is possible to see. Example: Visibility is reduced by fog.
Fog
A cloud at ground level that reduces visibility. Example: Fog is covering the runway.
PRACTICE 03
Conditions and decisions
Listen to the term, recall its meaning and reveal an example.
Crosswind
Wind blowing across the aircraft’s direction of travel. Example: We expect a crosswind on landing.
Turbulence
Irregular air movement that can cause the aircraft to move abruptly. Example: We are experiencing turbulence.
Icing
A build-up of ice on an aircraft. Example: The crew reports icing on the wing.
Deviation
A departure from an intended route. Example: We request a deviation around the weather.
Divert
To fly to a destination other than the one originally planned. Example: The crew decides to divert.
Alternate
An alternative aerodrome that may be used if needed. Example: The crew checks the weather at the alternate.
Obstruction
Something that blocks a route or area. Example: A vehicle is an obstruction on the taxiway.
Bird strike
A collision between a bird and an aircraft. Example: The crew reports a possible bird strike.
Leak
An unintended escape of fluid or air. Example: The crew notices a hydraulic fluid leak.
Ventilation
The movement or supply of air in an enclosed space. Example: The crew reports a ventilation problem.
PRACTICE 04
Use the words in context
Look closely at each image where shown, then choose the best answer.
Check your answers and compare your speaking with the model, then see your practice debrief.
This independent list contains operational words for ground movements, weather, flight and unexpected problems. Each card has a plain definition and a short example.
Do I need to memorise every aviation term?
Aim to explain routine and unexpected situations clearly. If the exact word does not come, describe the object or situation in plain English and check that you are understood.
Is vocabulary the only ICAO language skill?
No. The rating also considers Pronunciation, Structure, Fluency, Comprehension and Interactions; the overall level is the lowest of the six scores.
How should pilots and controllers practise aviation vocabulary?
Listen, recall the meaning, then use it in a short operational sentence. Describe an image without reading the answer and replay words that are difficult to recognise.
Is this an actual exam vocabulary list?
No. The exercises are original independent practice. Test formats vary by provider.
