The ICAO airport code or location indicator is a four-letter code designating aerodromes around the world. These codes, as defined by the International Civil Aviation Organization and published quarterly in ICAO Document 7910: Location Indicators , are used by air traffic control and airline operations such as flight planning . ICAO codes are also used to identify other aviation facilities such as weather stations , international flight service stations or area control centers , whether or not they are located at airports. Flight information regions are also identified by a unique ICAO-code.
21-402: Aberporth Airport ( ICAO : EGFA ) ( Welsh : Maes Awyr Aber-porth ) is situated southwest of Aberporth , Ceredigion , Wales . The airport is being developed as West Wales Airport for domestic flights. It is also developing as a centre for the deployment of civil and military unmanned aerial vehicles (UAVs), known as 'drones'. The airport underwent major improvements in 2008 which extended
42-423: A Watchkeeper crashed into a lane near the airfield; there were no injuries. ICAO airport code The recommendations for ICAO airport codes were adopted on 24 March 1959, and came into force on 1 October the same year. ICAO codes are separate and different from IATA codes , the latter of which have three letters and are generally used for airline timetables , reservations, and baggage tags. For example,
63-533: A brand-new asphalt runway was built, with other extensions of the hangar apron occurring during 1968 and 1971. During the 1960s Aberporth was the HQ of the RAE Ranges Division. RAF Aberporth 1940-46 & 1959-84 The following military units were posted here at some point: RAE Aberporth 1939-73 The following units were posted here at some point: Polish Army Resettlement Corps Depot 1946-50 The airfield
84-474: Is a pseudo-code, used in flight plans for aerodromes with no ICAO code assigned. ICAO codes are sometimes updated. Johannesburg Airport in Johannesburg , South Africa, for instance, was formerly known as Jan Smuts International Airport, with code FAJS. When the airport was renamed O. R. Tambo International Airport, its ICAO code was updated to FAOR. Some airports have two ICAO codes, usually when an airport
105-538: Is a service that involves the tracking of flights, aircraft and airport activity, often using software . Flight tracking enables travellers as well as those picking up travellers after a flight to know whether a flight has landed or is on schedule, for example to determine whether it is time to go to the airport. Aircraft carry ADS-B transponders, which transmit information such as the aircraft ID, GPS position, and altitude as radio signals. These radio transmission are collected by civilian ADS-B receivers located in
126-711: Is based in the United Kingdom . On the other hand, IATA codes do not provide geographic reference. For example, LHR, representing Heathrow, does not enable one to deduce the location of the airport LHV with any greater certainty; it is William T. Piper Memorial Airport in Lock Haven, Pennsylvania in the United States . There are a few exceptions to the regional structure of the ICAO code that have been historically for political or administrative reasons. RAF Mount Pleasant air base in
147-525: Is currently in its infancy, but is set to grow significantly as systems get more connected. Despite the progress, many abrupt events like sudden weather changes are not captured by existing flight trackers because they take their information not from the airplane itself but from dispatcher centers which often do not know the actual status of plane's whereabouts. Flight tracking software is available for commercial operators to track their aircraft and monitor if they deviate from an agreed flight path. If they do,
168-482: Is partly delegated to authorities in each country, while IATA codes, which have no geographic structure, must be decided centrally by IATA. The first one or two letters of the ICAO code indicate the country; the remaining letters identify the airport. ICAO codes are used partly for geographical context. For example, the ICAO code for Heathrow International Airport in London, is EGLL, with its first letters reflecting that it
189-679: Is shared by civilian and military users. Frankfurt Airport in Frankfurt , Germany, for instance, has been assigned ICAO code EDDF while Rhein-Main Air Base was assigned ICAO code EDAF until its closure. Sion Airport in Switzerland has code LSGS while its military facilities have the ICAO code LSMS. Brussels Airport in Brussels , Belgium, has the ICAO code EBBR for its civilian facilities, and Melsbroek Air Base has been assigned ICAO code EBMB, even though
210-574: The British military , as well as for launching civilian rockets for atmospheric research . The site is currently managed by QinetiQ with air traffic services provided by NATS . The airport is mainly used for testing unmanned aerial vehicles in a area called the West Wales UAV Centre which is connected to the Welsh Government created ParcAberporth . No. 636 Volunteer Gliding Squadron RAF
231-673: The Falkland Islands , for instance, is assigned the ICAO code EGYP as though it were in the United Kingdom, but nearby civilian Port Stanley Airport is assigned SFAL, consistent with South America . Saint Pierre and Miquelon is controlled by France, and airports there are assigned LFxx as though they were in Europe. Kosovo is assigned the code BKxx grouping it with Greenland and Iceland rather than its geographical neighbors which have Lxxx (described below). Jerusalem International Airport
SECTION 10
#1732890517561252-599: The Jezero Crater on Mars is assigned the special ICAO code JZRO. Codes beginning with I (Ixx and Ixxx) are often used for navigational aids such as radio beacons, while the Q code is reserved for international radiocommunications and non-geographical special use. In Russia , Latin letter X, or its Morse / Baudot Cyrillic equivalent Ь , are used to designate government, military, and experimental aviation airfields in internal airfield codes similar in structure and purpose to ICAO codes but not used internationally. ZZZZ
273-563: The IATA code for London 's Heathrow Airport is LHR and its ICAO code is EGLL. IATA codes are commonly seen by passengers and the general public on flight-tracking services such as FlightAware . In general IATA codes are usually derived from the name of the airport or the city it serves, while ICAO codes are distributed by region and country. Far more aerodromes (in the broad sense) have ICAO codes than IATA codes, which are sometimes assigned to railway stations as well. The selection of ICAO codes
294-760: The length of the runway from 945 to 1,257 m (3,100 to 4,124 ft). The site was previously RAF Aberporth , a former Royal Air Force satellite station which used by the RAF Army Cooperation Command , the site was also used the Royal Aircraft Establishment (RAE), the Defence Research Agency (DRA) and the Defence Evaluation and Research Agency (DERA) under the control of the Ministry of Defence until 2001. During 1956,
315-564: The site being an outstation of PDE Fort Halstead and Royal Arsenal Woolwich. The range was previously the Aberporth Anti-Aircraft Artillery Range and the Projectile Development Range along with The Aberporth Range . The Clausen Rolling Platform was built there to test radar and launchers against the rolling motion of ships at sea, without needing to go to sea. It is used for testing rockets by
336-552: The style LFddnn , where dd indicates the department while nn is a sequential counter. The French Federation of Ultralight Motorized Gliders was formally named the keeper of these codes. Aerodrome de Torreilles in France, for instance, has code LF6651. In Antarctica many aerodromes have pseudo ICAO-codes with AT and two digits, while others have proper codes from countries performing air control such as NZ for New Zealand . Tracking (commercial airline flight) Flight tracking
357-515: The two airports share runways and ground and air control facilities. In small countries like Belgium or the Netherlands, almost all aerodromes have an ICAO code. For larger countries like the UK or Germany this is not feasible, given the limited number of letter codes. Some countries have addressed this issue by introducing a scheme of sub-ICAO aerodrome codes; France, for example, assigns pseudo ICAO codes in
378-453: The vicinity of the aircraft. These ADS-B receivers are only able to collect information on flights within radio-range of their position, so the data they collect is usually sent to a central server which aggregates feeds from numerous individual receivers throughout the world. Flight tracking can be integrated with travel management and travel tracking services, allowing increased automation of travel software. This application of flight tracking
399-691: Was assigned both LLJR (its Israeli persona) as well as OJJR (its Jordanian persona), but the airport itself fell into disuse. In the contiguous United States and Canada, many airports have ICAO codes that are simply copies of their three-letter IATA codes, with the geographical prefix added on (e.g., YEG and CYEG both refer to Edmonton International Airport , while IAD and KIAD both refer to Washington Dulles International Airport ). This similarity does not extend to Alaska (PAxx), Hawaii (PHxx), or U.S. territories. Kahului Airport on Maui , for instance, has an IATA code of OGG and an ICAO code of PHOG. ICAO airport codes do not begin with I or J or X or Q, though
420-431: Was present between October 1996 and December 2001 Aberporth Aerodrome has a CAA Ordinary Licence (Number P859) that allows flights for the public transport of passengers or for flying instruction as authorised by the licensee. The aerodrome is not licensed for night use. The airfield is being used as a base for Thales Watchkeeper WK450 military unmanned aerial vehicle (UAV) trials over Cardigan Bay . On 13 June 2018
441-646: Was used as a Polish Army Resettlement Corps Depot between 1946 and 1950. The nearby range, MoD Aberporth started out as a Second World War British Army firing range. Due to the threat of Nazi Germany invasion, the Projectile Development Establishment moved from Fort Halstead to the range during 1940, with the Royal Air Force Combined Services Projectile Development Establishment being in existence between September 1943 and January 1945.
