Aviation English for pilots is a specialized skill that combines standard radiotelephony (RT) phraseology with plain English for non-routine situations. Every commercial pilot flying internationally must pass an ICAO English assessment to demonstrate they can communicate clearly and safely with air traffic control and other crew members.
This guide covers ICAO Level 4 requirements, essential RT phrases for every phase of flight, standard phraseology patterns, plain English strategies, and the best preparation resources for the ICAO English test.
Prepare for Your ICAO English Test
The most effective way to prepare is 1-on-1 tutoring with an aviation English specialist who knows the ICAO assessment format.

ICAO English Requirements for Pilots
ICAO Annex 1 requires all pilots flying internationally to demonstrate English proficiency at Level 4 or above. The assessment covers six skill areas.
| Skill | Level 4 (Operational) | Level 5 (Extended) |
|---|---|---|
| Pronunciation | Understandable, minor errors | Clear, near-native |
| Structure | Basic grammar, some errors | Good control, few errors |
| Vocabulary | Adequate for routine situations | Wide range, precise |
| Fluency | Slows down occasionally | Smooth, natural pace |
| Comprehension | Mainly understands | Understands all |
| Interactions | Handles routine exchanges | Handles unexpected turns |
Level 4 is valid for 4 years. Level 5 is valid for 6 years. Level 6 (Expert) has no expiry. If you are preparing for the test, check your current English level first and aim for B2 before starting aviation-specific preparation.
Standard RT Phraseology
RT phraseology is the standardized language used in pilot-ATC communication. Every phrase has a specific meaning. Using the wrong phrase can lead to misunderstandings.
| Phrase | Meaning | Example |
|---|---|---|
| Roger | Received and understood | "Roger, climb to FL350." |
| Wilco | Will comply | "Wilco, descend to 5,000 feet." |
| Say again | Please repeat | "Say again, heavy static." |
| Stand by | Wait, I will respond shortly | "Stand by for taxi clearance." |
| Affirm / Negative | Yes / No | "Affirm, we have the latest weather." |
| Mayday | Life-threatening emergency | "Mayday, Mayday, engine failure." |
| Pan-Pan | Urgent but not life-threatening | "Pan-Pan, medical issue on board." |
| Read back | Repeat the message back | "Read back clearance to destination." |
Taxi and Takeoff Communication
Taxi and takeoff are high-workload phases where clear communication is critical. Every call follows a standard format.
| Phase | Pilot Call | ATC Response |
|---|---|---|
| Initial call | "Ground, Speedbird 456, request push and start, Stand B17." | "Speedbird 456, push and start approved, face east." |
| Taxi request | "Ground, Speedbird 456, request taxi to Runway 27L." | "Speedbird 456, taxi via Delta, hold short Runway 27L." |
| Takeoff clearance | "Tower, Speedbird 456, holding short Runway 27L, ready for departure." | "Speedbird 456, line up and wait, wind 270 at 12." |
| Rolling takeoff | "Speedbird 456, rolling, Runway 27L." | "Speedbird 456, contact Departure 118.7, good day." |
Note the structure: who you are calling, who you are, what you want, where you are. Always include your callsign in every transmission. Do not say "please" or "thank you" on RT -- keep it concise and professional.
En-Route and Approach Communication
During the cruise and approach phases, pilots communicate position reports, level changes, and weather deviations. These calls follow ICAO standard phraseology.
| Situation | Standard Call |
|---|---|
| Level change | "Control, Speedbird 456, request climb to FL380." |
| Position report | "Control, Speedbird 456, passing waypoint AMLET at FL350." |
| Weather deviation | "Control, Speedbird 456, requesting 20 degrees right for weather." |
| Approach handover | "Approach, Speedbird 456, descending to 5,000 feet, QNH 1013." |
| ILS intercept | "Speedbird 456, established ILS Runway 27L." |
Emergency and Non-Routine Communication
When things go wrong, pilots switch from RT phraseology to plain English. ICAO Level 4 requires you to handle non-routine situations using clear, precise plain English.
Technical Problem
- "We have an engine vibration on number two."
- "Request return to departure airport."
- "We need to dump fuel before landing."
- "Landing gear indication is abnormal."
- "We are declaring an emergency and requesting priority."
Medical Emergency
- "We have a passenger with chest pain."
- "Request medical assistance on arrival."
- "Is there a doctor available on the airport?"
- "We need an ambulance at the gate."
- "The passenger is conscious and breathing."
In these situations, clarity matters more than brevity. Do not worry about using perfect RT structure. Say what is happening, what you need, and what you are doing about it.
ICAO English Test Format
The ICAO English test is structured in four parts and takes about 30 minutes. Understanding the format helps you prepare effectively.
| Part | Duration | What You Do |
|---|---|---|
| Warm-up | 3-5 min | Introduce yourself, describe your flying experience |
| RT listening | 5-7 min | Listen to RT recordings and explain what happened |
| Scenario | 8-10 min | Respond to a non-routine situation using plain English |
| Interactive | 5-7 min | Discuss aviation topics, give opinions, handle follow-up questions |
The test assesses pronunciation, structure, vocabulary, fluency, comprehension, and interactions. You are scored from Level 1 (Pre-Elementary) to Level 6 (Expert). Level 4 is the minimum for international flying.
