According to Article 43 of the Chicago Convention, the ICAO is composed of an assembly, a council, and other organs possibly necessary.

Assembly (Article 48 f )

The Council is the executive body, responsible for the day to day management. He is regarded as the main body of ICAO. Representatives of 36 States elected by the Assembly for a term of three years. Here are both the most important air traffic States and States of the main geographical areas of the world are taken into account. The main tasks of the Council include performing the directions of the Assembly, an annual reporting to selbige and appointing an Air Transport Committee and an Air Navigation Commission. For the adoption of the recommended by the Air Navigation Commission changes the Annexe is required in accordance with Article 90 a two-thirds majority of Council votes.

Air Navigation Commission ( Article 56 f )

The Air Navigation Commission shall be composed of 19 members who are appointed by the Council. These individuals must have experience in scientific and practical fields of aviation. They mainly deal with the changes of the Annexes to the Chicago Convention.

SAR (Search and Rescue)

In the report issued jointly by ICAO and IMO International Aeronautical and Maritime Search and Rescue Manual operation of search and rescue services in many nations due. This facility, known as abbreviated SAR service, guarantees fast and adequate assistance for air and distress cases.

ICAO alphabet

The ICAO alphabet was introduced on 1 March 1956 as the international watch word alphabet by ATC Commission of ICAO. Its use is binding agreement in international radio communications between the Member States of the ITU (Appendix 14 to the Radio Regulations ). It is therefore used worldwide in aerospace and in many other areas, including by NATO, as Buchstabiertafel.

ICAO Codes

The ICAO codes are used to uniquely identify airports and heliports on the one hand and on the other airlines. The ICAO codes are used primarily by air traffic control, and plan the route and are not to be confused with the existing of only three letter IATA codes for airports with which individuals are confronted much more frequently because they, on reservations, tickets time sheets are used at the airport, etc..

ICAO Annexe

The " Annexe " ( trailer ) for international aviation agreements provide for a uniform international management of various practical aspects of aviation and thus enable international air transport without special training of flight personnel for each country and ensure minimum standards of services for the aviation industry.
