Who is this exam for?

The ICAO language test is mandatory for all commercial pilots, private pilots with instrument ratings, and air traffic controllers operating internationally. Achieving Level 4 (operational), 5 (extended), or 6 (expert) is required to maintain licensing validity.

Try an Emergency Reporting Task

In Part 2 of the ICAO speaking test, you must listen to non-routine aviation audio emergency scenarios and report details clearly. Here is a sample task card.

ICAO Speaking Task: Emergency Briefing

Scenario: Bird Strike on Departure
"Immediately after rotation (takeoff), the aircraft flies through a flock of birds. The crew hears a loud bang from the left engine, followed by severe vibrations and rising exhaust gas temperature (EGT)..."

You must deliver a structured report addressing:
  • Describe what happened during takeoff and the immediate state of the engine.
  • Explain the safety actions required (e.g. engine shutdown, fuel dumping, immediate return).
  • Issue a simulated radiotelephony message to Air Traffic Control (ATC) using standard phraseology and plain English.
  • Formulate a passenger briefing explaining why you are returning to the airport.

Speaking Test Structure

The face-to-face 1-on-1 interview takes approximately 20 to 30 minutes, testing a candidate's ability to communicate clearly in routine and non-routine aviation situations.

Part 1: Aviation Background Interview

5 Minutes

The examiner asks conversational questions about your training history, piloting or controller background, type ratings, and flight experience.

Pro Tip: Keep answers structured. While conversational, maintain correct professional terminology, using precise aviation vocabulary rather than simple slang.

Part 2: Interactive Emergency Comprehension

8 - 10 Minutes

You listen to audio recordings of various non-routine aviation emergencies (e.g. hydraulic failure, severe turbulence, or passenger medical events).

You must report exactly what occurred, explain the risks, and propose immediate piloting decisions.

Pro Tip: Active listening is key! Note crucial parameters like altitude, airspeed, fuel state, and the exact nature of the malfunction to provide a comprehensive briefing.

Part 3: Radio Simulation & Dialogue

8 Minutes

A simulated radiotelephony dialogue where the candidate interacts with the examiner (playing the pilot or controller). You receive instructions, read back clearances, and manage non-routine situations.

Pro Tip: Use standard phraseology first! If standard phraseology is insufficient for a complex emergency, switch to clear, concise plain English.
