International Civil Aviation Organization
The International Civil Aviation Organization (ICAO) is an agency within the United Nations that is tasked with developing, reviewing and maintaining a body of regulations dedicated to many aspects of aviation and aviation law, chief among them being safety.
The agency was established by the Chicago Convention of 1944 and is headquartered in Montreal, Canada. It is made up of delegates from several nations around the world.
Beyond advancing safety and security, ICAO is also involved in setting standards for aircraft operation, pilot licensing, rules of airspace, crash investigations and airline communications technology.
