A Comparative Study: Language Proficiency Requirements for Pilots, Air Traffic Controllers, and Aircraft Technicians

Aviation English is used by different aviation personnel besides air traffic controllers and pilots. However, the ICAO language proficiency requirements are designed only for pilot-air traffic controller communications, addressing solely the listening and speaking skills. The goal of these requirements is to limit misunderstandings in the course of flight by bringing the knowledge of all pilots and air traffic controllers to an acceptable level. This article focuses on the comparison of the English language requirements posed on aircraft technicians as opposed to pilots and air traffic controllers. ICAO language proficiency requirements provided a beginning in recognizing the significance of the English language, but there is a need for further development of language proficiency requirements dedicated to aircraft maintenance technicians, as their job requires them to read and understand English texts. The aircraft maintenance manuals, service bulletins, and other documentation provide instructions that have to be closely followed to ensure safety. The need for English proficiency in aircraft maintenance is acknowledged, however, there is still a need for guidance on the language requirements.
