An IATA airport code , also known as an IATA location identifier , IATA station code , or simply a location identifier , is a three-letter geocode designating many airports and metropolitan areas around the world, defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.
41-597: Busselton Margaret River Airport ( IATA : BQB , ICAO : YBLN ), formerly known as Busselton Regional Airport , is located in the Busselton suburb of Yalyalup , 6.5 km (4.0 mi) from the town centre. Busselton is a major regional centre in the South West of Western Australia , 220 km (140 mi) south of Perth and at the edge of the Margaret River wine region . Busselton Regional Airport
82-567: A new airport is built, replacing the old one, leaving the city's new "major" airport (or the only remaining airport) code to no longer correspond with the city's name. The original airport in Nashville, Tennessee, was built in 1936 as part of the Works Progress Administration and called Berry Field with the designation, BNA. A new facility known as Nashville International Airport was built in 1987 but still uses BNA. This
123-509: Is GSN and its IATA code is SPN, and some coincide with IATA codes of non-U.S. airports. Canada's unusual codes—which bear little to no similarity with any conventional abbreviation to the city's name—such as YUL in Montréal , and YYZ in Toronto , originated from the two-letter codes used to identify weather reporting stations in the 1930s. The letters preceding the two-letter code follow
164-405: Is a system that allows aircraft pilots to control the lighting of an airport or airfield's approach lights , runway edge lights , and taxiways via radio. At some airfields, the airport/aerodrome beacon may also be ARCAL controlled. ARCAL is most common at non-towered airports or little-used airfields where it is neither economical to light the runways all night, nor to provide staff to turn
205-408: Is available for both ends and low-intensity runway lights can be activated by radio ( Pilot Controlled Lighting ). Two illuminated windsocks are on site. Non-precision instrument approaches include GNSS (GPS) approaches to both runways, and a sole NDB (ADF) approach to runway 21. IATA airport code The assignment of these codes is governed by IATA Resolution 763, and it is administered by
246-617: Is available. However, many railway administrations have their own list of codes for their stations, such as the list of Amtrak station codes . Airport codes arose out of the convenience that the practice brought pilots for location identification in the 1930s. Initially, pilots in the United States used the two-letter code from the National Weather Service (NWS) for identifying cities. This system became unmanageable for cities and towns without an NWS identifier, and
287-523: Is different from the name in English, yet the airport code represents only the English name. Examples include: Due to scarcity of codes, some airports are given codes with letters not found in their names: The use of 'X' as a filler letter is a practice to create three-letter identifiers when more straightforward options were unavailable: Some airports in the United States retained their NWS ( National Weather Service ) codes and simply appended an X at
328-493: Is home to the largest fly-in fly-out workforce in Western Australia outside Perth, resulting in the airport seeing numerous mining charters for BHP , Fortescue and Rio Tinto each week. Busselton Margaret River Airport has a single 2,460 metre long by 45 metre wide runway (03/21) and is rated at Code E with capability to handle aircraft the size and weight of an Airbus A330 . Precision Approach Path Indicator
369-513: Is in conjunction to rules aimed to avoid confusion that seem to apply in the United States, which state that "the first and second letters or second and third letters of an identifier may not be duplicated with less than 200 nautical miles separation." Thus, Washington, D.C. area's three airports all have radically different codes: IAD for Washington–Dulles , DCA for Washington–Reagan (District of Columbia Airport), and BWI for Baltimore (Baltimore–Washington International, formerly BAL). Since HOU
410-543: Is not followed outside the United States: In addition, since three letter codes starting with Q are widely used in radio communication, cities whose name begins with "Q" also had to find alternate codes, as in the case of: IATA codes should not be confused with the FAA identifiers of U.S. airports. Most FAA identifiers agree with the corresponding IATA codes, but some do not, such as Saipan , whose FAA identifier
451-416: Is used for William P. Hobby Airport , the new Houston–Intercontinental became IAH. The code BKK was originally assigned to Bangkok–Don Mueang and was later transferred to Suvarnabhumi Airport , while the former adopted DMK. The code ISK was originally assigned to Gandhinagar Airport (Nashik's old airport) and later on transferred to Ozar Airport (Nashik's current airport). Shanghai–Hongqiao retained

#1732787392377492-571: The Canadian transcontinental railroads were built, each station was assigned its own two-letter Morse code : When the Canadian government established airports, it used the existing railway codes for them as well. If the airport had a weather station, authorities added a "Y" to the front of the code, meaning "Yes" to indicate it had a weather station or some other letter to indicate it did not. When international codes were created in cooperation with
533-546: The airport in Sydney, Nova Scotia . To activate the lights, the pilot clicks the radio transmit switch on the ARCAL frequency a certain number of times within a specified number of seconds. There are two types of ARCAL systems — type J and type K. Type J systems are activated by keying the microphone five times within five seconds, while type K is initially activated by clicking seven times within five seconds. Once activated,
574-622: The Government of Western Australia placed the construction of the new terminal building on hold until a major commercial airline committed to interstate services that were shown to be viable. In September 2019, it was announced that Jetstar was to launch a subsidised service to Melbourne in April 2020. As a result of the service confirmation, the Western Australian government announced it would spend an extra $ 3.2 million upgrading
615-608: The IATA's headquarters in Montreal , Canada. The codes are published semi-annually in the IATA Airline Coding Directory. IATA provides codes for airport handling entities, and for certain railway stations. Alphabetical lists of airports sorted by IATA code are available. A list of railway station codes , shared in agreements between airlines and rail lines such as Amtrak , SNCF , and Deutsche Bahn ,
656-585: The U.S. For example, several airports in Alaska have scheduled commercial service, such as Stebbins and Nanwalek , which use FAA codes instead of ICAO codes. Thus, neither system completely includes all airports with scheduled service. Some airports are identified in colloquial speech by their IATA code. Examples include LAX and JFK . Pilot Controlled Lighting Pilot-controlled lighting ( PCL ), also known as aircraft radio control of aerodrome lighting ( ARCAL ) or pilot-activated lighting ( PAL ),
697-481: The United States, because "Y" was seldom used in the United States, Canada simply used the weather station codes for its airports, changing the "Y" to a "Z" if it conflicted with an airport code already in use. The result is that most major Canadian airport codes start with "Y" followed by two letters in the city's name (for example, YOW for O tta w a , YWG for W innipe g , YYC for C algar y , or YVR for V ancouve r ), whereas other Canadian airports append
738-480: The airport for fly-in fly-out workers at its mines. Skywest Airlines/Virgin Australia Regional Airlines operated a service from Perth to Albany via Busselton from July 2011 until December 2014, before scaling it back to operate between Perth and Busselton before cancelling it altogether in April 2015. Between June and December 2014, upgrades to the terminal were made. In June 2015, funding
779-440: The airport itself instead of the city it serves, while another code is reserved which refers to the city itself which can be used to search for flights to any of its airports. For instance: Or using a code for the city in one of the major airports and then assigning another code to another airport: When different cities with the same name each have an airport, they need to be assigned different codes. Examples include: Sometimes,
820-418: The airport's former name, such as Orlando International Airport 's MCO (for Mc C o y Air Force Base), or Chicago's O'Hare International Airport , which is coded ORD for its original name: Or char d Field. In rare cases, the code comes from the airport's unofficial name, such as Kahului Airport 's OGG (for local aviation pioneer Jimmy H ogg ). In large metropolitan areas, airport codes are often named after
861-551: The airport's terminal. The commencement of the service was postponed eight times due to the COVID-19 pandemic . Flights began as part of a three-year trial of the route on 6 April 2022. The terminal upgrade was also postponed until after the three-year trial period. In April 2019, the airport was designated as an international alternate airport to Perth; previously the closest airports with this designation were Learmonth and Adelaide . In 2023, there were renewed calls to upgrade
SECTION 20
#1732787392377902-502: The code SHA, while the newer Shanghai–Pudong adopted PVG. The opposite was true for Berlin : the airport Berlin–Tegel used the code TXL, while its smaller counterpart Berlin–Schönefeld used SXF; the Berlin Brandenburg Airport has the airport code BER, which is also part of its branding. The airports of Hamburg (HAM) and Hannover (HAJ) are less than 100 nautical miles (190 km) apart and therefore share
943-477: The controller for a predetermined time interval ( Federal Aviation Administration standard is 15 minutes) that is generally adjustable. The five-second click count period begins upon receipt of the first squelch break and the control sequence will respond to the click counts from three, five, seven and stop. As an example, cycling the microphone button rapidly 15 times in five seconds will command "three, five, seven". Similarly, slowly clicking seven times may result in
984-934: The end. Examples include: A lot of minor airfields without scheduled passenger traffic have ICAO codes but not IATA codes, since the four letter codes allow more number of codes, and IATA codes are mainly used for passenger services such as tickets, and ICAO codes by pilots. In the US, such airfields use FAA codes instead of ICAO. There are airports with scheduled service for which there are ICAO codes but not IATA codes, such as Nkhotakota Airport/Tangole Airport in Malawi or Chōfu Airport in Tokyo, Japan. There are also several minor airports in Russia (e.g., Omsukchan Airport ) which lack IATA codes and instead use internal Russian codes for booking. Flights to these airports cannot be booked through
1025-557: The first three letters of the city in which it is located, for instance: The code may also be a combination of the letters in its name, such as: Sometimes the airport code reflects pronunciation, rather than spelling, namely: For many reasons, some airport codes do not fit the normal scheme described above. Some airports, for example, cross several municipalities or regions, and therefore, use codes derived from some of their letters, resulting in: Other airports—particularly those serving cities with multiple airports—have codes derived from
1066-478: The following format: Most large airports in Canada have codes that begin with the letter "Y", although not all "Y" codes are Canadian (for example, YUM for Yuma, Arizona , and YNT for Yantai , China), and not all Canadian airports start with the letter "Y" (for example, ZBF for Bathurst, New Brunswick ). Many Canadian airports have a code that starts with W, X or Z, but none of these are major airports. When
1107-597: The form of " YYZ ", a song by the rock band Rush , which utilizes the Morse code signal as a musical motif. Some airports have started using their IATA codes as brand names , such as Calgary International Airport (YYC) and Vancouver International Airport (YVR). Numerous New Zealand airports use codes that contain the letter Z, to distinguish them from similar airport names in other countries. Examples include HLZ for Hamilton , ZQN for Queenstown , and WSZ for Westport . Predominantly, airport codes are named after
1148-424: The intensity of type K systems may then be turned to low, medium, or high intensity settings by keying the microphone three, five, or seven times within five seconds, respectively. If runway identification lights are also controlled by type K ARCAL, they may be turned off by keying the microphone three times. When either type of system is activated, a 15-minute countdown starts, after which the lights turn off. While
1189-487: The international air booking systems or have international luggage transferred there, and thus, they are booked instead through the airline or a domestic booking system. Several heliports in Greenland have 3-letter codes used internally which might be IATA codes for airports in faraway countries. There are several airports with scheduled service that have not been assigned ICAO codes that do have IATA codes, especially in
1230-403: The lights are already on, especially if the lights were activated by another aircraft. This is so that the lighting does not turn off at a critical moment, such as when crossing the runway threshold. When in operation, the receiver awaits a squelch break on the tuned VHF frequency and begins counting "clicks" in a five-second period to determine pilot intent. The pilot commanded output is held by
1271-416: The lights are on, whenever a lighting command is issued, whether it changes the lighting intensity or not, the fifteen-minute countdown is reset. At some airfields, the lights may flash once to warn pilots that the lights are about to go off, before turning off two minutes later. When using ARCAL, it is strongly recommended that aircraft on final approach to the airfield issue a fresh lighting command, even if
Busselton Margaret River Airport - Misplaced Pages Continue
1312-612: The name of the airport itself, for instance: This is also true with some cities with a single airport (even if there is more than one airport in the metropolitan area of said city), such as BDL for Hartford, Connecticut 's B ra dl ey International Airport or Baltimore's BWI, for B altimore/ W ashington I nternational Airport ; however, the latter also serves Washington, D.C. , alongside Dulles International Airport (IAD, for I nternational A irport D ulles) and Ronald Reagan Washington National Airport (DCA, for D istrict of C olumbia A irport). The code also sometimes comes from
1353-416: The one they are located in: Other airport codes are of obscure origin, and each has its own peculiarities: In Asia, codes that do not correspond with their city's names include Niigata 's KIJ , Nanchang 's KHN and Pyongyang 's FNJ . EuroAirport Basel Mulhouse Freiburg , which serves three countries, has three airport codes: BSL, MLH, EAP. Some cities have a name in their respective language which
1394-462: The runway lighting on and off. It enables pilots to control the lighting only when required, saving electricity and reducing light pollution. The ARCAL frequency for most aerodromes is usually the same as the UNICOM / CTAF frequency, although in some rare cases, a second ARCAL frequency may be designated to control the lighting for a second runway separately. An example of the latter is runway 18/36 at
1435-506: The same first and middle letters, indicating that this rule might be followed only in Germany. Many cities retain historical names in their airport codes, even after having undergone an official name/spelling/transliteration change: Some airport codes are based on previous names associated with a present airport, often with a military heritage. These include: Some airports are named for an administrative division or nearby city, rather than
1476-500: The station code of Malton, Mississauga , where it is located). YUL is used for Montréal–Trudeau (UL was the ID code for the beacon in the city of Kirkland , now the location of Montréal–Trudeau). While these codes make it difficult for the public to associate them with a particular Canadian city, some codes have become popular in usage despite their cryptic nature, particularly at the largest airports. Toronto's code has entered pop culture in
1517-456: The terminal before the conclusion of the three-year trial period after the success of the new service and increases in mining flights, with annual passenger numbers jumping from 25,000 before the pandemic to 95,000 by 2023. In March 2024 Jetstar commenced flights to Sydney after the success of the Melbourne service. In June 2024, a new Royal Flying Doctor Service facility opened. Busselton
1558-515: The two-letter code of the radio beacons that were the closest to the actual airport, such as YQX in Gander or YXS in Prince George . Four of the ten provincial capital airports in Canada have ended up with codes beginning with YY, including: Canada's largest airport is YYZ for Toronto Pearson (as YTZ was already allocated to Billy Bishop Toronto City Airport , the airport was given
1599-529: The use of two letters allowed only a few hundred combinations; a three-letter system of airport codes was implemented. This system allowed for 17,576 permutations, assuming all letters can be used in conjunction with each other. Since the U.S. Navy reserved "N" codes, and to prevent confusion with Federal Communications Commission broadcast call signs , which begin with "W" or "K", the airports of certain U.S. cities whose name begins with one of these letters had to adopt "irregular" airport codes: This practice
1640-510: Was allocated for further upgrades and redevelopment of the airport. As part of the funding agreement, Margaret River was officially added to the title of the airport in October 2015. In 2017, a $ 69.7 million redevelopment of the airport commenced which included: As part of the development, a new terminal building was proposed to be built in front of the new Code E Apron to help facilitate future interstate and international services. In early 2018,
1681-507: Was opened on 15 March 1997 by Premier of Western Australia Richard Court replacing Busselton Aerodrome, established in 1940, that was used extensively during World War II . A Government of Western Australia subsidised service operated from Perth to Busselton from 1997 to 2001 (via Margaret River Airport from 1999). It was operated by Skywest Airlines (now Virgin Australia Regional Airlines ), Maroomba Airlines and Skippers Aviation . In 2007, Rio Tinto launched its first flight from
