Effective and efficient communication in aviation is the indispensable condition of safety.

The ICAO English Language Proficiency Test service provided by ICAO4U Company is dedicated to ensure effective and efficient communication within the aviation industry. This forms an indispensable condition for the safety of both passengers and crew members.

The company’s primary mission is to develop and maintain communication standards that adhere to the International Civil Aviation Organization (ICAO) guidelines, which play a crucial role in establishing a safe and efficient global aviation network.

By offering comprehensive language proficiency testing and training, ICAO4U helps pilots, air traffic controllers, and other aviation professionals achieve the required levels of linguistic competence, thereby reducing the risk of miscommunication and ultimately promoting a higher level of safety within the industry.


Some of the deadliest aviation accidents resulted from miscommunication.

  • Avianca Flight 52 Long Island 1990/ 65 passengers died,
  • Air Florida Flight 1990 Virginia 1982/ 78 passengers died,
  • Dan Air Flight 1008 Canary Islands 1980/ 146 passengers died,
  • American Airlines Flight 965 1995/ 159 passengers died,
  • Pan Am Flight 1736 KLM 4805 Tenerife/ 583 passengers died.

In some cases, it was just one word misheard, sometimes ignoring the message or failure to use correct phraseology or basic grammar mistake… At ICAO4U we are taking practical effort to ensure safety in the air and on the ground. 

And that’s why… our mission is effectively summarised by the statement: 

Let the Safety Do the Talking

It is the mission of ICAO4U to constantly develop and build aviation communication skills in the English language among the pilots performing flights in the skies supervised by EASA.

Our goal is to make sure that in 2030 all aviation personnel performing their duties in Europe will communicate in English fluently, confidently, correctly and understandably. 

Effective and efficient communication in aviation is the indispensable condition of safety. English language communication which observes strictly the standards recognized by ICAO and EASA ensures communication comfort and situational awareness of pilots and all aviation personnel.

Universal application of one uniformed and recognized communication standard constitutes the opportunity for mutual understanding both en-route and during the performance of aerodrome operations. This results in:

  • mutual understanding and support, 
  • prevention and avoidance of dangerous situations,
  • traffic fluency,
  • development and update of piloting competence,
  • international trainings participation, 
  • exchange of opinions and knowledge.

Universally used aviation English is the synonym of mutual respect both in the air and on the ground.
