People who work in aviation need to be able to communicate effectively in voice only (for radio), as well as in face-to-face situations like pre-flight briefings, training and interacting with other crew members.
From a safety perspective, this communication needs to be in the language that is used locally by pilots and air traffic service providers. In Australia as with many other countries, the language is English.
The Aviation English Language Proficiency assessment is a measure of someone’s ability to communicate in English using an aviation-relevant assessment process. Avion is approved by CASA to conduct level 6 AELP assessments.
