AEL, or Aviation English Language, is a standardized form of English used in the aviation industry. It ensures clear communication between pilots, air traffic controllers, and other personnel, which is crucial for safety and efficiency in air travel. AEL includes specific vocabulary and phrases that are universally understood in aviation contexts. The use of AEL is mandated by the International Civil Aviation Organization (ICAO) to minimize misunderstandings that could lead to accidents. Pilots and air traffic controllers are required to demonstrate proficiency in AEL to ensure they can communicate effectively in various situations, including emergencies.
