ICAO plays a vital role in flight safety by setting global standards for aviation practices, including aircraft design, flight operations, air traffic management, and crew training. It provides safety protocols that help minimize risks and ensure consistent safety measures across different countries. ICAO also promotes the adoption of new technologies and procedures to improve air traffic control, reduce accidents, and respond effectively to emergencies, thus contributing to safer skies worldwide. These efforts help maintain high levels of safety in international air travel.
