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. In the United States, the ICAO codes are usually the same as the IATA code, with a prefix of "K" - LAX is KLAX. In the rest of the world the codes are unrelated, as the IATA code is phonic and the ICAO code is location-based; for example, Charles de Gaulle ICAO:LFPG, IATA:CDG. 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 the three letter airline 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 Aer Lingus numbered 111 would be written as "EIN111" and pronounced "Shamrock One-One-One" on the radio, while a similarly numbered Japan Airlines flight would be written as "JAL111" and "Japan Air One-One-One". ICAO maintains the standards for aircraft registration ("tail numbers"), including the alphanumeric codes that identify the country of registration. ICAO statute The 8th edition of the Convention on International Civil Aviation includes modifications from 1948 up to year 2000. The ICAO refers to its current edition of the convention the statute, and designates it as ICAO Doc 7300/8. The convention had 18 annexes: ICAO standards The ICAO also standardizes certain functions for use in the airline industry, such as the Aeronautical Message Handling System AMHS; this probably makes it a standards organization. Regions and regional offices The ICAO has seven regional offices serving nine regions: 1. Asia and Pacific, Bangkok, Thailand 2. Middle East, Cairo, Egypt 3. Western and Central Africa, Dakar, Senegal 4. South America, Lima, Peru 5. North America, Central America and Caribbean, Mexico City, Mexico 6. Eastern and Southern Africa, Nairobi, Kenya 7.
