The international language used in aviation is English. The International Civil Aviation Organization (ICAO) mandates English as the standard language for communication in air traffic control and among pilots worldwide. This requirement facilitates effective communication, reduces misunderstandings, and enhances safety in the increasingly global aviation industry. While some regions may use their native languages, English proficiency is crucial for personnel in international aviation contexts. The widespread use of English helps bridge language barriers, ensuring that pilots and air traffic controllers can collaborate efficiently across different countries and cultures.
