English Language Proficiency for Aeronautical Communication

A test to assess ICAO English Language Proficiency for pilots and air traffic controllers

Discover ELPAC

ELPAC (English Language Proficiency for Aeronautical Communication) is an ICAO English language proficiency test specifically designed for air traffic controllers and pilots and reflects the range of tasks undertaken in air traffic control and pilot communications.

ICAO recognition

The ELPAC test fully meets ICAO standards and recommended practises. The ELPAC test for air traffic controllers is fully recognised by ICAO for being in compliance with ICAO Doc 9835. The ELPAC test for pilots is being reviewed by ICAO. Test construct and test format is similar in both versions of the ELPAC test and we are expecting a positive decision soon.
