Initially, after the signing of the Chicago Convention, there was a Temporary International Civil Aviation Organization (Provisional International Civil Aviation Organisation - PICAO). After the entry into force in April 4 1947 of the Chicago Convention on 1-second sessionAssembly held in Montreal in May 1947 PICAO was renamed the ICAO.

The main objectives of ICAO, in accordance with the provisions of the Chicago Convention, are the issues of global significance to international civil aviation:

  • develop the principles and techniques of international air navigation;
  • foster the planning and development of international air transport so as to ensure the safe and orderly development of the international Civil Aviation;
  • the promotion of art and design of aircraft operation for peaceful purposes;
  • encourage the development of airways, airports and air navigation facilities for international GA;
  • meet the needs of the peoples of the world for safe, regular, efficient and economical air transport;
  • prevent economic waste caused by unreasonable competition;
  • ensure full respect of the rights of fair and for each of them opportunities to use the airline, engaged in international air traffic;
  • avoid discrimination in the relations between states;
  • ensuring the safety of international air navigation;
  • promoting the development of international civil aeronautics in all its aspects.

Composition and status of ICAO determined by the provisions of the Chicago Convention, which is, in fact, is the charter of ICAO. In accordance with the Chicago Convention, ICAO consists of the Assembly (Assembly), the Board (with the subordinate bodies) and Secretariat (Secretariat).

International standards (SARPs) for convenience, as Annexes to the Chicago Convention. For the safety and regularity of international air navigation deemed necessary to the uniform application of the requirements included the Contracting States in international standards. According to Article 38 the Chicago Convention, in the case of non-compliance with an international standard of the Contracting States shall notify the Council of ICAO of the differences between the national aviation regulations or practices of a State and the provisions of the International Standard.

Uniform application of the requirements included in the Recommended Practices is regarded as desirable in the interest of safety, regularity and efficiency of international air navigation. Although the Chicago Convention and does not impose any obligations in respect of Recommended Practice, the Council requested the ICAO Contracting States to notify differences not only with the international standards, but with the Recommended Practices.

ICAO released a series of technical publications, as well as special editions, which are not included in any of the series of technical publications (such as "Product of aeronautical charts ISAO" or "meteorological table".

Procedures for Air Navigation Services (Procedures of Air Navigation Service - PANS) are approved by the Council of ICAO. Designed for use worldwide, they comprise operating rules, which have not yet received the status of SARPs, as well as materials more permanent character which is considered too detailed, so they can be included in the Annex, or is susceptible to frequent amendment, for which the process provided for by the Chicago Convention, it would be too cumbersome. Currently, there are four main document PANS: Doc 4444 «Rules of the Air and Air Traffic Services"; Doc 8168 «Aircraft Operations" (Tom 1 «Flight Procedures" and Tom 2 «Construction of Visual Flight and Instrument Flight"); Doc 8400 «Abbreviations and Codes ICAO»; Doc 7030 «Regional Supplementary Procedures."

All of the globe by the ICAO Council is divided into nine areas of air navigation:

  • 1. Africa and the Indian Ocean (AIF);
  • 2. South-East Asia (SEA);
  • 3. European (EUR);
  • 4. North Atlantic (NAT);
  • 5. North American (NAM);
  • 6. South African (SAM);
  • 7. Caribbean (CAR);
  • 8. Middle East (MID);
  • 9. Pacific (PAC).

Regional Supplementary Procedures (Supplementary Procedures - SUPPS) have the same status as PANS, but apply only in the respective regions. They are developed inconsolidated form, since some of them apply to overlapping regions or are common to two or more regions.

Technical manuals that are prepared under the authority of the Secretary-General ICAO, provide guidance and information, developing and supplementing the International Standards, Recommended Practices and PANS, and serve to assist in their application.

Aeronautical Tany also prepared with the approval of the Secretary-General on the recommendations of ICAO regional air navigation meetings and decisions made by the Council of ICAO. They detail requirements for facilities and services for international air navigation in the respective regions, aeronautical ICAO. The Aeronautical plans are amended periodically to reflect changes in requirements and regulations related to the implementation of the recommended facilities and services.

Circulars ICAO, which is also produced with the approval of the Secretary-General ICAO, provide specific information of interest to Contracting States, including studies on technical subjects.
