The Hellenic Civil Aviation Authority (HCAA) is the national authority responsible for overseeing civil aviation in Greece. Established to ensure the safety and efficiency of air travel, the HCAA regulates airports, air traffic, and airline operations within the country. It also implements international aviation standards set by organizations like the International Civil Aviation Organization (ICAO). In addition to safety regulations, the HCAA manages airspace and coordinates with other countries to facilitate international flights. The authority plays a crucial role in promoting the growth of the aviation sector in Greece, supporting tourism and economic development through improved air connectivity.
