International Civil Aviation Organization

The International Civil Aviation Organization (or ICAO , in English International Civilian Aviation Organization or ICAO ) is an international organization who depends on the the United Nations. Its role is to take part in the development of the standards which allow the standardization of international aeronautical transport (the flights inside the same country are not concerned with the ICAO). Its head office is located at Montreal.

The council of the ICAO adopts the standards and recommendations regulating English navigation (: SARP, Standard and Recommended Practices ), the division of the radio frequencies, the licenses of the personnel of aviation, the air traffic, etc It defines also the protocols to be followed at the time of the investigations into the plane crashes, protocols which are respected by the countries signatories of the Convention of Chicago.

One should not confuse the ICAO (official intergovernmental international organization) with the AITA ( IATA ) which is a private association of airline companies (of which adhesion is not obligatory) and whose head office is also located at Montreal.

Organization

Created in November 1944 by 55 countries, the ICAO comprises 190 Member States (1) and has 7 regional offices (Bangkok, Dakar, Cairo, Lima, Mexico City, Nairobi and Paris). The assembly elects every three years a council, trained representatives of 36 states. The Council is assisted of a technical Commission (Commission of Aerial navigation) made up of 19 members chosen for their expertise. The Secretariat of the Organization is composed of 5 directions (aerial navigation, air transport, technical collaboration, legal affairs, administration).

(1) Since the adhesion of Montenegro, on February 12th, 2007, the only States non-member of the ICAO are the Dominique, Liechtenstein, the Saint ‐ Siège and Tuvalu.

Standards

Since 1993, the Organization lowered the emission standards of oxide of nitrogen of 20 %.

The ICAO and the AITA have each one their system of coding of the Aéroport S and airline companies :

the coding of the airports of the ICAO uses 4 letters according to a classification géographique :

the first character indicates a continental area
the second character indicates the country or an area of the country
the two following characters are allotted country by country
to see for example the list of the French aerodromes.

the coding of the airports of AITA uses 3 mnemonic letters, mainly used by the airline companies for the commercial nomenclature and information on the flights, the reservation of tickets or the labelling and the routing of the luggage and freight. By ex. :

CDG for the Airport Charles de Gaulle, with Roissy.
ORY for Orly.

The ICAO is also responsible for systems of coding concerning the Aéronef S:
