EUROCONTROL, in partnership with ZHAW (the Zurich University of Applied Sciences) and ENOVATE, has developed a test of English Language Proficiency for Aeronautical Communication (ELPAC). The goal was to help Air Navigation Service Providers (ANSP), Aircraft Operators (AO), National Supervisory Authorities (NSA) and Training Organisations (TO) meet the ICAO language profi­ciency requirements.

ELPAC is designed for operational air traffic controllers and pilots. It reflects the range of tasks undertaken in air traffic control and pilot communications. ELPAC tests English language proficiency at ICAO level 4 (operational) and level 5 (extended). A separate ELPAC test is available for organisations wishing to test their staff at ICAO level 6.

The fact that the ELPAC test is currently the only language proficiency test endorsed by ICAO is a testimony to the validity and integrity of ELPAC.

Access conditions

Organisations intending to use ELPAC will be required to:

  • sign a licence agreement with EUROCONTROL (respecting test security, confidentiality of data and maintaining ELPAC test standards);
  • select qualified personnel (English language and operational aviation experts) to receive training from EUROCONTROL as test administrator, marker, assessor and interlocutor;
  • have this personnel accredited (following a one week training course).

Once these conditions are fulfilled the organisation will be given access to the ELPAC test and can start testing their licence holders.

ELPAC testing will be managed by selected examiners from the organisation using ELPAC. The testing will take place at the location of the user.
