International Civil Aviation Organization

From Free net encyclopedia

(Redirected from ICAO)

Image:ICAO.JPG 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. Assad Kotaite has served as President of the ICAO Council since 1976, but will retire from that post in August, 2006.

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 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 111" on the radio, while a similarly numbered Japan Airlines flight would be written as "JAL111" and "Japan Air 111".

ICAO Aircraft Registration Prefixes are used to identify the place where the aircraft registers at. For example, B-H is identified as Hong Kong, then we can know that B-HKE is a plane which is registered at Hong Kong. Take another example, D is known as Germany, therefore D-AILS is a plane which is registered at Germany.

Annex 11 - Air Traffic Services
Annex 12 - Search and Rescue
Annex 13 - Aircraft Accident and Incident Investigation

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.
