International Civil Aviation Organization

From Wikipedia, the free encyclopedia

The International Civil Aviation Organization (ICAO), an agency of the United Nations, codifies 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.

[edit] 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. Canada follows a similar pattern, where a prefix of "C" is usually added to an IATA code to find the ICAO code - YEG is CYEG. 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.

[edit] ICAO statute

The 9th edition of the Convention on International Civil Aviation includes modifications from 1948 up to year 2006. The ICAO refers to its current edition of the convention the statute, and designates it as ICAO Doc 7300/9.

The convention had 18 annexes:

• Annex 1 - Personnel Licensing
• Annex 2 - Rules of the Air
• Annex 3 - Meteorological Service for International Air Navigation
• Annex 4 - Aeronautical Charts
• Annex 5 - Units of Measurement to be Used in Air and Ground Operations
• Annex 6 - Operation of Aircraft - Aeroplanes
• Annex 7 - Aircraft Nationality and Registration Marks
• Annex 8 - Airworthiness of Aircraft
• Annex 9 - Facilitation
• Annex 10 - Aeronautical Telecommunications
• Annex 11 - Air Traffic Services
• Annex 12 - Search and Rescue
• Annex 13 - Aircraft Accident and Incident Investigation
• Annex 14 - Aerodromes - Aerodrome Design and Operations, Heliports
• Annex 15 - Aeronautical Information Services
• Annex 16 - Environmental Protection - Aircraft Noise
• Annex 17 - Security: Safeguarding International Civil Aviation Against Acts of Unlawful Interference
• Annex 18 - The Safe Transport of Dangerous Goods by Air

[edit] 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.

[edit] 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. Europe and North Atlantic, Paris, France

[edit] ICAO and Climate Change

Emissions from international aviation are specifically excluded from the targets agreed under the Kyoto Protocol. Instead, the Protocol invites developed countries to pursue the limitation or reduction of emissions through the International Civil Aviation Organisation (ICAO). ICAO’s environmental committee continues to consider the potential for using market-based measures such as trading and charging, but this work is unlikely to lead to global action. It is currently developing guidance for states who wish to include aviation in an emissions trading scheme (ETS) to meet their Kyoto commitments, and for airlines who wish to participate voluntarily in a trading scheme. It is also looking at guidance on how charges can be applied to aircraft greenhouse gas emissions, although a recent ICAO Resolution prevents states from introducing a scheme for international aviation before 2007.

Emissions from domestic aviation are included within the Kyoto targets agreed by countries. This has led to some national policies such as fuel and emission taxes for domestic air travel in the Netherlands and Norway respectively. Although some countries tax the fuel used by domestic aviation, there is no duty on kerosene used on international flights. (Aviation Environment Federation [1])
