International Civil Aviation Organization
From Freepedia
The International Civil Aviation Organization (ICAO), an agency of the United Nations, develops the principles and techniques of international air navigation and fosters the planning and development of international air transport to ensure safe and orderly growth. The ICAO Council adopts standards and recommended practices concerning air navigation, prevention of unlawful interference, and facilitation of border-crossing procedures for international civil aviation.
In addition, the ICAO defines the protocols for air accident investigation followed by transport safety authorities in countries signatory to the Convention on International Civil Aviation, commonly known as the Chicago Convention. See NTSB, TSB, AAIB, BFU, and BEA.
Its headquarters are located in the Quartier International of Montreal, Canada.
The ICAO should not be confused with the International Air Transport Association (IATA), a trade organization for airlines also headquartered in Montreal.

ICAO Codes
Both ICAO and IATA have their own airport and airline code systems. ICAO uses 4-letter airport codes, and 3-letter airline codes. IATA is scheduled to eventually switch its codes to the ICAO standard.
ICAO is also responsible for issuing alphanumeric aircraft type codes that contain 3 or 4 characters. These codes provide the identification that is typically used in flight plans. An example of this is the Boeing 747 that would use (depending on the variant) B741, B742 ,B743, etc.
ICAO provides telephony designators to aircraft operators worldwide. These consist of a three letter identifer and a one or two word designator. They are usually, but not always, similar to the aircraft operator name. Thus the identifer for Aer Lingus is EIN and the designator is Shamrock while Japan Airlines International is JAL and Japan Air . So a flight by either company that is numbered 111 would be written as "EIN111" and on the radio would be pronounced "Shamrock 111" or "JAL111" and "Japan Air 111".
