About International Civil Aviation Day
The purpose of International Civil Aviation Day is to help generate and reinforce worldwide awareness of the importance of international civil aviation to the social and economic development of States, and of the unique role of ICAO in helping States to cooperate and realize a truly global rapid transit network at the service of all mankind.
Every five years, coinciding with ICAO anniversaries (2014/2019/2024/2029/etc.), the ICAO Council establishes a special anniversary theme for International Civil Aviation Day. Between these anniversary years, Council representatives select a single theme for the full four-year intervening period.
