The Convention on International Civil Aviation, drafted in 1944 by 54 nations, was established to promote cooperation and “create and preserve friendship and understanding among the nations and peoples of the world.”
Known more commonly today as the ‘Chicago Convention’, this landmark agreement established the core principles permitting international transport by air, and led to the creation of the specialized agency which has overseen it ever since – the International Civil Aviation Organization (ICAO).
It is Known then and today more commonly as the ‘Chicago Convention’, this landmark agreement laid the foundation for the standards and procedures for peaceful global air navigation. It set out as its prime objective the development of international civil aviation “…in a safe and orderly manner”, and such that air transport services would be established “on the basis of equality of opportunity and operated soundly and economically.”
The Chicago Convention also formalized the expectation that a specialized International Civil Aviation Organization (ICAO) would be established, in order to organize and support the intensive international co-operation which the fledgling global air transport network would require.
ICAO’s core mandate, then as today, was to help States to achieve the highest possible degree of uniformity in civil aviation regulations, standards, procedures, and organization.
Because of the usual delays expected in ratifying the Convention, the Chicago Conference presciently signed an Interim Agreement which foresaw the creation of a Provisional ICAO (PICAO) to serve as a temporary advisory and coordinating body.
The PICAO consisted of an Interim Council and an Interim Assembly, and from June 1945 the Interim Council met continuously in Montreal, Canada, and consisted of representatives from 21 Member States. The first Interim Assembly of the PICAO, the precursor to ICAO’s triennial Assemblies in the modern era, was also held in Montreal in June of 1946.
On 4 April 1947, upon sufficient ratifications to the Chicago Convention, the provisional aspects of the PICAO were no longer relevant and it officially became known as ICAO. The first official ICAO Assembly was held in Montreal in May of that year.
During this march to the modern air transport era, the Convention’s Annexes have increased in number and evolved such that they now include more than 12,000 international standards and recommended practices (SARPs), all of which have been agreed by consensus by ICAO’s now 192 Member States.
These SARPs, alongside the tremendous technological progress and contributions in the intervening decades on behalf of air transport operators and manufacturers, have enabled the realization of what can now be recognized as a critical driver of socio-economic development and one of humanity’s greatest cooperative achievements – the modern international air transport network.
