English Language Proficiency

The International Civil Aviation Organization (ICAO) has directed its member states, including Australia, to assess and certify that all flight crew and air traffic controllers are competent in radiotelephony communications as well as proficient in the language used. The ICAO language proficiency standards became effective on 5 March 2008. CASA has implemented the ICAO standards to enhance safety in flight operations.

English is the aviation language used in Australia; it is also the standard international aviation language. Therefore English shall be the language the Australian Civil Aviation Safety Authority (CASA) assesses for flight crew language proficiency.
