56-559: Bahrain International Airport ( IATA : BAH , ICAO : OBBI ) ( Arabic : مطار البحرين الدولي , romanized: Maṭār al-Baḥrayn al-dwalī ) is the international airport of Bahrain . Located on Muharraq Island , adjacent to the capital Manama and the city of Muharraq , it serves as the hub for the national carrier Gulf Air . The airport is managed by the Bahrain Airport Company . Established in 1927, it

112-654: A 3,000-strong staff, BAS is an ISAGO-accredited Ground Service Provider. Overseeing the Kingdom's oil, gas, and petroleum assets, Bahrain Jet Fuel Company (BJFCO) is a joint venture between Bahrain Airport Company and the nogaholding . BJFCO is currently constructing a fuel farm complex in the northeastern area of the airport as part of a major restructuring of the Kingdom's aviation fueling industry. The Awal Private Terminal at Bahrain International Airport

168-408: A handling capacity of 4,700 bags per peak hour. The new terminal cost 1.1 billion USD . The terminal features check-in halls, check-in desks, passport control booths, E-gates, security lanes, a 9,000 sqm duty-free retail space, lounges, food and beverage zones, 24 departure gates, and 7,000 new parking spaces both at-grade and in multi-story facilities. Through the airport's 25,000 sqm Cargo Terminal,

224-567: 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

280-481: A new local airline, Gulf Aviation Company, was formed – the forerunner of Gulf Air . The company started with only one aircraft, a second-hand Anson Mark II , which was used initially on services to Dhahran . However, within two years, the fleet had expanded to four de Havilland aircraft and DC-3s for use on a steadily growing network in the Persian Gulf. This established Bahrain on an international stage. It

336-868: A second consecutive ISO recertification for quality, environmental and occupational health and safety management systems in March 2024 and becoming the first airport in the world to achieve the International Air Transport Association Environmental Assessment Certification in November 2024. The airport's new $ 1.1 billion terminal opened on 28 January 2021. At 210,000 square meters, the Passenger Terminal increases Bahrain International Airport's (BIA) capacity to 14 million passengers and 130,000 air traffic movements per year with

392-643: A twice-weekly frequency. In 1937, Bahrain saw the regular service of the Empire sea planes . The landing strip of these giants on the water was from where the marina club is located in Mina Salman today. From the 1950s, BOAC operated several services a week through Bahrain. These included weekly services to Karachi , Singapore , Hong Kong and three times a week to Sydney . 1950 was a significant year not only for Muharraq as an international airport, but also for Bahrain's commercial aviation history. In this year,

448-590: A wide range of services are offered, including export cargo sales, transhipment, inter-airport trucking, and customs clearance. Bahrain is also the regional hub for DHL Aviation . With 115 weekly flights and 250 vehicles, DHL operates an integrated air and land network. Other cargo and logistics companies operating out of the airport include FedEx, TNT Express, Aramex, and Global Logistical Services (GLS). Bahrain Airport Services (BAS) provides airport services at Bahrain International Airport (BIA). Supported by

504-419: Is " ultrasonic ", but the older meaning sometimes still lives on, as in the word superheterodyne The tip of a bullwhip is generally seen as the first object designed to reach the speed of sound. This action results in its telltale "crack", which is actually just a sonic boom . The first human-made supersonic boom was likely caused by a piece of common cloth, leading to the whip's eventual development. It's

560-509: 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

616-439: Is a dedicated facility designed to provide exclusive services for VIP passengers, government officials, and private aviation clients. The terminal offers private check-in , security screening , and immigration procedures . The 4,000 m² terminal is operated by Hala Bahrain, a subsidiary owned by Bahrain Airport Company . 2017 2018, and 2019) The airport is situated in central Muharraq and has transportation connections with

672-627: Is administered by 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 ,

728-617: 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

784-428: Is crack formation faster than the speed of sound in a brittle material. The word supersonic comes from two Latin derived words ; 1) super : above and 2) sonus : sound, which together mean above sound, or faster than sound. At the beginning of the 20th century, the term "supersonic" was used as an adjective to describe sound whose frequency is above the range of normal human hearing. The modern term for this meaning

840-523: 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

896-513: 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

952-444: Is more complex. The main key to having low supersonic drag is to properly shape the overall aircraft to be long and thin, and close to a "perfect" shape, the von Karman ogive or Sears-Haack body . This has led to almost every supersonic cruising aircraft looking very similar to every other, with a very long and slender fuselage and large delta wings, cf. SR-71 , Concorde , etc. Although not ideal for passenger aircraft, this shaping

1008-543: 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

1064-658: Is the Persian Gulf 's oldest international airport. The origins of Bahrain's international airport dates to 1927 when a chartered flight to Bahrain landed. The first scheduled commercial airliner to arrive in Bahrain , in 1932, was a flight from London to Delhi operated on a Handley Page H.P.42 aircraft named Hannibal . The H.P.42 carried only 24 passengers, and the flight from London had taken several days of flying at speeds of 100 miles per hour. Through this regularly scheduled service, Bahrain became established as one of

1120-416: 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

1176-545: The COVID-19 pandemic and the vehicle was put up for sale. Most modern fighter aircraft are supersonic aircraft. No modern-day passenger aircraft are capable of supersonic speed, but there have been supersonic passenger aircraft , namely Concorde and the Tupolev Tu-144 . Both of these passenger aircraft and some modern fighters are also capable of supercruise , a condition of sustained supersonic flight without

1232-571: 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

1288-660: The Persian Gulf 's first international airports. During World War II, the airport was used by the United States Army Air Forces Air Transport Command Central African Wing, being designated as Station # 13. It functioned as a stopover en route to Abadan Airport , Iran or Sharjah Airport , in present-day UAE on the Karachi - Cairo route. From 1943 until Bahrain's independence in December 1971,

1344-573: The Royal Air Force maintained a military installation at the airfield known initially as RAF Bahrain and from 1963 as RAF Muharraq . The majority of these facilities were later acquired by the Bahraini flag carrier airline, Gulf Air , while a small portion continues to be utilized by the U.S. Navy as Aviation Support Unit (ASU) Bahrain. In 1936, the operation of H.P.42 aircraft from London to India via Bahrain had been stepped up to

1400-594: The ThrustSSC . The vehicle, driven by Andy Green , holds the world land speed record, having achieved an average speed on its bi-directional run of 1,228 km/h (763 mph) in the Black Rock Desert on 15 October 1997. The Bloodhound LSR project planned an attempt on the record in 2020 at Hakskeenpan in South Africa with a combination jet and hybrid rocket propelled car. The aim was to break

1456-562: The Tupolev Tu-160 and Rockwell B-1 Lancer are also supersonic-capable. The aerodynamics of supersonic aircraft is simpler than subsonic aerodynamics because the airsheets at different points along the plane often cannot affect each other. Supersonic jets and rocket vehicles require several times greater thrust to push through the extra aerodynamic drag experienced within the transonic region (around Mach 0.85–1.2). At these speeds aerospace engineers can gently guide air around

1512-524: The fuselage of the aircraft without producing new shock waves , but any change in cross area farther down the vehicle leads to shock waves along the body. Designers use the Supersonic area rule and the Whitcomb area rule to minimize sudden changes in size. However, in practical applications, a supersonic aircraft must operate stably in both subsonic and supersonic profiles, hence aerodynamic design

1568-471: The molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of sound, and Mach numbers for a steadily moving object may change. In water at room temperature supersonic speed means any speed greater than 1,440 m/s (4,724 ft/s). In solids, sound waves can be polarized longitudinally or transversely and have higher velocities. Supersonic fracture

1624-420: The speed of sound ( Mach  1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level , this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h). Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic . Flights during which only some parts of the air surrounding an object, such as

1680-467: The speed of sound decreases somewhat with altitude, due to lower temperatures found there (typically up to 25 km). At even higher altitudes the temperature starts increasing, with the corresponding increase in the speed of sound. When an inflated balloon is burst, the torn pieces of latex contract at supersonic speed, which contributes to the sharp and loud popping noise. To date, only one land vehicle has officially travelled at supersonic speed,

1736-546: The wave motion travelling through the bullwhip that makes it capable of achieving supersonic speeds. Most modern firearm bullets are supersonic, with rifle projectiles often travelling at speeds approaching and in some cases well exceeding Mach 3 . Most spacecraft are supersonic at least during portions of their reentry, though the effects on the spacecraft are reduced by low air densities. During ascent, launch vehicles generally avoid going supersonic below 30 km (~98,400 feet) to reduce air drag. Note that

1792-425: The 1980s and 1990s, major facelifts took place and several major airline companies made the airport a destination. In 1994, a US$ 100 million terminal was inaugurated which boosted the airport's maximum capacity to 10 million passengers a year. In July 1994, Gulf Air started nonstop service to New York on Airbus A340s. Due to the length of the route, westbound flights occasionally had to make a refuelling stop. In 2008,

1848-481: 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 . Supersonic Supersonic speed is the speed of an object that exceeds

1904-481: 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

1960-440: 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,

2016-414: The airport opened new passenger facilities, which included a wide area that could accommodate four 747 aircraft. In 1976, the airport marked another significant first with the inauguration of supersonic flights, which saw the start-up of regular BA Concorde service between London and Bahrain. Pan Am introduced direct flights to New York in December 1976. It operated the route with Boeing 747SPs. In

2072-491: The airport was placed under the management of the newly created Bahrain Airport Company , which falls under the umbrella of the Gulf Air Holding Company, which in turn is owned by Mumtalakat , Bahrain's sovereign wealth fund. On 8 October 2009, it was announced that BHD 1.8 billion expansion of Bahrain International Airport will start in 2010. The expansion, planned over the next 30 years, intended to triple

2128-418: 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

2184-547: The capital city Manama through the Airport Avenue roadway and Shaikh Isa Causeway . Bahrain International Airport is served 24/7 by several taxi operators. Bahrain Public Transport Company (BPTC) provides buses.

2240-502: 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

2296-934: 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

2352-435: The ends of rotor blades, reach supersonic speeds are called transonic . This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on

2408-460: The existing record, then make further attempts during which (the members of) the team hoped to reach speeds of up to 1,600 km/h (1,000 mph). The effort was originally run by Richard Noble who was the leader of the ThrustSSC project, however following funding issues in 2018, the team was bought by Ian Warhurst and renamed Bloodhound LSR. Later the project was indefinitely delayed due to

2464-557: 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

2520-478: 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

2576-597: 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

2632-487: 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

2688-612: 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

2744-416: 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

2800-463: The passenger capacity to 27 million a year. In April 2010, United Airlines began service to Washington, D.C., via Kuwait. The carrier flew the route with a Boeing 777. United left Bahrain in January 2016. Since 2020 the airport has placed an increased effort to enhance the sustainability of the airport, including a LEED gold certification for the new Terminal Passenger Building in 2021, achieving

2856-506: 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

2912-500: 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

2968-515: 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

3024-405: The use of an afterburner . Due to its ability to supercruise for several hours and the relatively high frequency of flight over several decades, Concorde spent more time flying supersonically than all other aircraft combined by a considerable margin. Since Concorde's final retirement flight on November 26, 2003, there are no supersonic passenger aircraft left in service. Some large bombers , such as

3080-529: 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

It began to attract other carriers such as Middle East Airlines , Air India , Air Ceylon and Iran Air – mostly operating Dakotas . In December 1961, a new passenger terminal opened at the airport. During 1970–1971, RAF Muharraq was scaled back and eventually closed. In December 1971,
