The International Civil Aviation Organization (ICAO) is an agency of the United Nations that establishes international standards and regulations for civil aviation. ICAO was created in 1944 through the Convention on International Civil Aviation to promote safe and efficient air travel. ICAO sets standards for aviation safety, air navigation, and airport infrastructure and helps developing countries benefit from air transport. It is headquartered in Montreal, Canada and has three main bodies: the Assembly, Council, and Secretariat.
