ICAO Scenario Explanation
ICAO Scenario Explanation tasks require candidates to describe an aviation situation, explain what is happening and discuss possible actions. The speaker must communicate clearly, logically and fluently using operational aviation English.
What Is ICAO Scenario Explanation?
In an ICAO scenario explanation task, candidates must explain a developing aviation situation. This may involve weather problems, technical issues, delays, diversions or emergency conditions. The speaker must explain the situation clearly and describe possible decisions.
This task checks communication ability in operational contexts where reasoning and decision-making must be explained clearly.
A good scenario explanation should:
- describe the situation clearly
- identify the main issue
- explain possible causes
- discuss risks
- suggest possible actions
- communicate logically and fluently
