Under ICAO Assembly Resolution A29-1 the date of 7 December was officially declared as International Civil Aviation Day (ICAD).

The purpose of this annual celebration is to establish and reinforce global awareness of the importance of international civil aviation to the social and economic development of States and the general fostering of international connectivity, peace and prosperity.

Council determined that a single ICAD theme would be established covering the full four-year period in between ICAO anniversary years. In line with this decision, Council approved “Working Together to Ensure No Country is Left Behind” as the theme to be celebrated by States for the period 2015-2018 inclusive.
