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.
68-652: Laoag International Airport ( IATA : LAO , ICAO : RPLI ) is an airport serving the general area of Laoag , the capital city of the province of Ilocos Norte in the Philippines . It is the only airport in Ilocos Norte and is the northernmost international airport in the Philippines. It has one 2,784-meter runway and is designated as a secondary/alternate international airport by the Civil Aviation Authority of
136-493: 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
204-536: A government-published set of Presidential proclamations. Section 7 of the Copyright Act of 1909 (later codified as Section 8 of title 17 U.S.C.) provided that "No copyright shall subsist ... in any publication of the United States Government, or any reprint, in whole or in part, thereof ..." Section 7 also contained a "savings clause", which stated that "The publication or republication by
272-550: 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
340-470: A round-the-world flight to celebrate the plane's 77th birthday. The airport was also where 4 FA-50 light fighter aircraft were stored during the testing of Israeli radars on Paredes Air Station in Pasuquin, Ilocos Norte. There are plans to store FA-50s on the airport as a warning squadron for any disaster/threat to the northern part of the Philippines. The terminal building's ceiling and floor were damaged by
408-577: A staging area for flights and air missions against Japanese forces in Northern Luzon by April and became an important refueling point for planes en route to Okinawa and an even more important emergency and rescue base for planes returning from Formosa and China. After the war, the airfield was converted into a civilian airport. It mostly catered to domestic flights from Manila and international flights from nearby countries of China , Hong Kong and Singapore and as far as Honolulu , Hawaii . In 2003,
476-499: A state or local government may be subject to copyright. Some states have placed much of their work into the public domain by waiving some or all of their rights under copyright law. For example, the constitution and laws of Florida have placed its government's works in the public domain. Unorganized territories (such as American Samoa and the former Trust Territory of the Pacific Islands ) are treated, for copyright purposes, as
544-499: 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
612-574: 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
680-513: 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
748-532: 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

Whenever the contractor asserts claim to copyright in works other than computer software, the government, and others acting on its behalf, are granted a license to reproduce, prepare derivative works , distribute, perform and display the copyrighted work. For computer software produced under FAR contract, the scope of the government's license does not include
884-466: Is printed", with the proviso "that no publication reprinted from such stereotype or electrotype plates and no other Government publication shall be copyrighted". The provision in the Printing Act concerning copyright of government works was probably the result of the "Richardson Affair" , which involved an effort in the late 1890s by Representative James D. Richardson (1843–1914) to privately copyright
952-432: Is published or republished commercially, it has frequently been the practice to add some "new matter" in the form of an introduction, editing, illustrations, etc., and to include a general copyright notice in the name of the commercial publisher. This in no way suggests to the public that the bulk of the work is uncopyrightable and therefore free for use. "To make the notice meaningful rather than misleading", section 403 of
1020-457: Is the extent of U.S. federal law. The U.S. government asserts that it can still hold the copyright to those works in other countries. Publication of an otherwise protected work by the U.S. government does not put that work in the public domain. For example, government publications may include works copyrighted by a contractor or grantee; copyrighted material assigned to the U.S. Government; or copyrighted information from other sources. Further,

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
1156-586: The Airbus A330 . A single terminal building serves both passenger and cargo traffic. As an international airport, it houses immigration desks for screening of arriving international passengers. It is also equipped with a carousel baggage at the reclaim area for passengers with checked-in items. The terminal previously had a combined capacity of 140 international and domestic passengers. It has since been expanded in 2021 to accommodate 200 international and 240 domestic passengers. Data from Civil Aviation Authority of
1224-561: 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
1292-619: The Department of Commerce under the Standard Reference Data Act. National Defense Authorization Act (NDAA), FY2020, granted civilian members of the faculty at twelve federal government institutions the authority to retain and own copyright of works produced in the course of employment for publication by a scholarly press or journal. The lack of copyright protection for works of the United States government does not apply to works of U.S. subnational governments. Thus, works created by
1360-535: The United States Postal Service are typically subject to normal copyright. Most USPS materials, artwork, and design and all postage stamps as of January 1, 1978, or after are subject to copyright laws. Works of the former United States Post Office Department are in the public domain (due to its former position as a cabinet department). 15 U.S.C. § 290e authorizes U.S. Secretary of Commerce to secure copyright for works produced by
1428-483: The copyright status of works by subnational governments of the United States is governed by its own set of laws. The first Federal statute concerning copyright in government publications was the Printing Law enacted in 1895 . Section 52 of that Act provided that copies of "Government Publications" could not be copyrighted. Prior to 1895, no court decision had occasion to consider any claim of copyright on behalf of
SECTION 20
#17328581350851496-471: 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 the use of two letters allowed only
1564-567: The military may differ significantly from civilian agency contracts. Civilian agencies and NASA are guided by the Federal Acquisition Regulations (FAR). There are a number of FAR provisions that can affect the ownership of the copyright. FAR Subpart 27.4—Rights in Data and Copyright provides copyright guidance for the civilian agencies and NASA. Additionally, some agencies may have their own FAR Supplements that they follow. Under
1632-454: The 1976 Act required that, when the copies consist " 'preponderantly of one or more works of the United States Government', the copyright notice (if any) identify those parts of the work in which copyright is claimed. A failure to meet this requirement would be treated as an omission of the notice", resulting, absent the application of some exception, in the loss of copyright protection. The Berne Convention Implementation Act of 1988 amended
1700-529: The Copyright Act that now govern U.S. Government work were enacted in 1976 as part of the Copyright Act of 1976 . The House Report to the enacted legislation stated that "the basic premise of section 105 of the bill is the same" as section 8 of the former title 17. Section 403 of the 1976 Act introduced a new provision concerning documents consisting preponderantly of one or more government works. In essence, such works would be denied copyright protection unless
1768-477: The FAR general data rights clause (FAR 52.227-14), the government has unlimited rights in all data first produced in performance of or delivered under a contract, unless the contractor asserts a claim to copyright or the contract provides otherwise. Unless provided otherwise by an Agency FAR Supplement, a contractor may assert claim to copyright in scientific and technical articles based on or containing data first produced in
1836-583: The Federal Government had no right to claim copyright in a work prepared by him for the Government. Other decisions had held that individuals could not have copyright in books consisting of the text of Federal or State court decisions, statutes, rules of judicial procedures, etc., i.e., governmental edicts and rulings. Copyright was denied on the grounds of public policy: such material as the laws and governmental rules and decisions must be freely available to
1904-445: The Government itself. Courts had, however, considered whether copyright could be asserted as to the text of laws, court decisions, governmental rules, etc., and concluded that such material were not subject to copyright as a matter of public policy. But other material prepared for State Governments by their employees, notably the headnotes, syllabi, annotations, etc. prepared by court reporters, had been held copyrightable on behalf of
1972-457: The Government, either separately or in a public document, of any material in which copyright is subsisting shall not be taken to cause any abridgment or annulment of the copyright or to authorize any use or appropriation of such copyright material without the consent of the copyright proprietor." The committee report on the bill that became the Act of 1909 explains that the savings clause was inserted "for
2040-511: 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 , is available. However, many railway administrations have their own list of codes for their stations, such as

The land on which the airport sits today is located near the Ilocos Norte sand dunes at the mouth of the Padsan River . During the American colonial period, a military airfield located in
2244-493: The State. Such copyrights for the benefit of the State were sustained by the courts. Two cases before 1895 may also be noted with regard to the question of the rights of individual authors (or their successors) in material prepared for, or acquired by, the United States Government. In Heine v. Appleton , an artist was held to have no right to secure copyright in drawings prepared by him as a member of Commodore Perry's expedition, since
2312-525: The States. The Copyright Act of 1909 was the first copyright statute to address government publications. Section 7 of the Act (later codified as Section 8 of title 17 U.S.C.) provided that "No copyright shall subsist ... in any publication of the United States Government, or any reprint, in whole or in part, thereof". Prior to the Printing Act of 1895, no statute governed copyright of U.S. government works. Court decisions had established that an employee of
2380-461: 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 . Copyright status of works by the federal government of
2448-520: The U.S. government. Their works therefore fall under § 105 and lack copyright protection. Certain works, particularly logos and emblems of government agencies, while not copyrightable, are still protected by other laws that are similar in effect to trademark laws. Such laws are intended to protect indicators of source or quality. For example, some uses of the Central Intelligence Agency logo, name, and initialism are regulated under
2516-521: The United States A work of the United States government is defined by the United States copyright law , as "a work prepared by an officer or employee of the United States Government as part of that person's official duties". Under section 105 of the Copyright Act of 1976 , such works are not entitled to domestic copyright protection under U.S. law and are therefore in the public domain . This act only applies to U.S. domestic copyright as that
2584-481: 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
2652-440: 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,
2720-515: The airport was an epicenter of concern for authorities during the 2002–2004 SARS outbreak during which it continued to receive flights from China and Singapore , two of the most affected countries. The airport became one of the stops of the Breitling DC-3 World Tour held in 2017. The aircraft, a Douglas DC-3 with the registration number HB-IRJ landed for refueling in April as part of

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

2856-491: 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
2924-399: The copies or phonorecords embodying any work or works protected under this title". Unlike works of the U.S. government, works produced by contractors under government contracts are protected under U.S. copyright law . The holdership of the copyright depends on the terms of the contract and the type of work undertaken. Contract terms and conditions vary between agencies; contracts to NASA and
2992-467: The court decisions. These cases may be said to have established the principle that material prepared by a government employee outside of the scope of the public policy rule was copyrightable; and that the employee who prepared such material on his own could secure copyright therein. There appears to be no court decision before 1895 dealing directly with the question of whether the United States Government might obtain or hold copyright in material not within
3060-425: The drawings belonged to the Government. In Folsom v. Marsh , where a collection of letters and other private writings of George Washington had been published and copyrighted by his successors, the purchase of the manuscripts by the United States Government was held not to affect the copyright. The contention of the defendant that the Government's ownership of the manuscripts made them available for publication by anyone
3128-919: 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
3196-444: The federal government purchased former U.S. President James Madison 's manuscripts from his widow, Dolley Madison , for $ 30,000. If this is construed as covering copyright as well as the physical papers, it would be an example of such a transfer. Works by certain independent agencies, corporations and federal subsidiaries may not be considered "government works" and may, therefore, be copyrightable. For instance, material produced by
3264-557: 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
3332-474: 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
3400-593: 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
3468-501: The headquarters and setting fire to a fuel dump. Similar attacks follow in the succeeding days until its abandonment on February 15, 1945 due to Commonwealth military and guerrilla raids. It was then recaptured on February 27, 1945. By April 1945 the airfield was again operational hosting fighter and transport aircraft. Colonel Arvid E.

4080-592: The public policy rule. But the question did arise with respect to State Governments. In the nineteenth century much of the public printing for the States was done under contract by private publishers. The publisher would not bear the expense of printing and publishing, however, unless he could be given exclusive rights. To enable the State to give exclusive rights to a publisher, a number of States enacted statutes providing that court reporters or other State officials who prepared copyrightable material in their official capacity should secure copyright in trust for or on behalf of

Under the revised Section 403, these benefits are denied to a work consisting predominantly U.S. Government works "unless the notice of copyright appearing on the published copies or phonorecords to which a defendant in the copyright infringement suit had access includes a statement identifying, either affirmatively or negatively, those portions of

The Sections of
