The international language of aviation is English. This universal aviation language is mandated by the International Civil Aviation Organization (ICAO) to ensure consistent communication among pilots, air traffic controllers, and other personnel around the world. The use of a single language helps mitigate misunderstandings that could arise due to language barriers in international air travel and operations. Proficiency in English includes understanding standardized phrases and terminology essential for safe and effective communication in-flight. It has become an integral aspect of global aviation standards, enhancing safety and efficiency in air traffic management.
