72-605: Kalamazoo/Battle Creek International Airport ( IATA : AZO , ICAO : KAZO , FAA LID : AZO ) is a county-owned public airport in Kalamazoo , Kalamazoo County , Michigan, US, 3 miles (4.8 km) southeast of Downtown Kalamazoo. The airport is located approximately 20 miles (32 km) west of the city of Battle Creek . It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2023-27, in which it

144-409: A defined barometric pressure . Generally, the pressure used to set the altimeter is the barometric pressure that would exist at MSL in the region being flown over. This pressure is referred to as either QNH or "altimeter" and is transmitted to the pilot by radio from air traffic control (ATC) or an automatic terminal information service (ATIS). Since the terrain elevation is also referenced to MSL,

216-493: 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

288-432: A few metres, in timeframes ranging from minutes to months: Between 1901 and 2018, the average sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970s. This was faster than the sea level had ever risen over at least the past 3,000 years. The rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022. Climate change due to human activities

360-567: 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

432-568: A new terminal was constructed to replace the 1920s terminal. The growth led to a terminal expansion in 1979, and the building increased from 12,000 to 30,000 square feet (2,800 m). The terminal was completely renovated in 1989, with the addition of a new concourse, an enlarged boarding area, and a new baggage claim area. The Kalamazoo Airport's 1958 terminal had two jetways and housed the air traffic control tower. A Non-Radar Approach Control, located in Battle Creek and servicing Kalamazoo,

504-438: A reference datum for mean sea level (MSL). It is also used in aviation, where some heights are recorded and reported with respect to mean sea level (contrast with flight level ), and in the atmospheric sciences , and in land surveying . An alternative is to base height measurements on a reference ellipsoid approximating the entire Earth, which is what systems such as GPS do. In aviation, the reference ellipsoid known as WGS84

576-529: A restaurant, and one of the region's only 4-D theaters . The museum is housed in two buildings, and is located on the south section of the field. The museum also has a fly in ramp, making it an attraction for many visiting pilots. In June and October 2011 the Air Zoo opened a new 50,000 square feet (4,600 m) building connecting it to the main building allowing all the attractions and exhibits to be in one easy to see location. The original building (East Campus)

648-470: A sharp reduction in greenhouse gas emissions, this may increase to hundreds of millions in the latter decades of the century. Local factors like tidal range or land subsidence will greatly affect the severity of impacts. For instance, sea level rise in the United States is likely to be two to three times greater than the global average by the end of the century. Yet, of the 20 countries with

720-681: Is categorized as a non-hub primary commercial service facility. The airport has an Airport Traffic Control Tower (ATCT) and a Terminal Radar Approach Control (TRACON). It has one passenger terminal and five gates. Three airlines operate flights in and out of AZO. Plans for an airport in Kalamazoo began in 1925. In May 1926, the City of Kalamazoo purchased 383 acres (1.55 km) near Portage and Kilgore roads and an airport opened. The first regular air mail service started in July 1928. In February 1929,

792-509: 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

864-417: Is an average surface level of one or more among Earth 's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datum  – a standardised geodetic datum  – that is used, for example, as a chart datum in cartography and marine navigation , or, in aviation, as the standard sea level at which atmospheric pressure

936-488: Is because the sea is in constant motion, affected by the tides, wind , atmospheric pressure, local gravitational differences, temperature, salinity , and so forth. The mean sea level at a particular location may be calculated over an extended time period and used as a datum . For example, hourly measurements may be averaged over a full Metonic 19-year lunar cycle to determine the mean sea level at an official tide gauge . Still-water level or still-water sea level (SWL)

1008-523: 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

1080-427: Is due to change in either the volume of water in the world's oceans or the volume of the oceanic basins . Two major mechanisms are currently causing eustatic sea level rise. First, shrinking land ice, such as mountain glaciers and polar ice sheets, is releasing water into the oceans. Second, as ocean temperatures rise, the warmer water expands. Many factors can produce short-term changes in sea level, typically within

1152-513: 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

1224-483: Is increasingly used to define heights; however, differences up to 100 metres (328 feet) exist between this ellipsoid height and local mean sea level. Another alternative is to use a geoid -based vertical datum such as NAVD88 and the global EGM96 (part of WGS84). Details vary in different countries. When referring to geographic features such as mountains, on a topographic map variations in elevation are shown by contour lines . A mountain's highest point or summit

1296-512: Is measured to calibrate altitude and, consequently, aircraft flight levels . A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales . Current sea level rise is mainly caused by human-induced climate change . When temperatures rise, mountain glaciers and polar ice sheets melt, increasing

1368-543: 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

1440-584: Is offered through Kal-Aero Flight Instruction. The Western Michigan University College of Aviation, founded in 1939, used the Kalamazoo/Battle Creek International Airport as a base for its flight school until 1997. In the early 1990s, the flight school began to outgrow the facilities, and, in 1997, the college moved to Battle Creek's W. K. Kellogg Airport , where all operations are presently housed. The WMU aviation unit at Kalamazoo has been used from time to time by

1512-450: Is the level of the sea with motions such as wind waves averaged out. Then MSL implies the SWL further averaged over a period of time such that changes due to, e.g., the tides , also have zero mean. Global MSL refers to a spatial average over the entire ocean area, typically using large sets of tide gauges and/or satellite measurements. One often measures the values of MSL with respect to

1584-727: Is the main cause. Between 1993 and 2018, melting ice sheets and glaciers accounted for 44% of sea level rise , with another 42% resulting from thermal expansion of water . Sea level rise lags behind changes in the Earth 's temperature by many decades, and sea level rise will therefore continue to accelerate between now and 2050 in response to warming that has already happened. What happens after that depends on human greenhouse gas emissions . If there are very deep cuts in emissions, sea level rise would slow between 2050 and 2100. It could then reach by 2100 slightly over 30 cm (1 ft) from now and approximately 60 cm (2 ft) from

1656-531: Is typically illustrated with the AMSL height in metres, feet or both. In unusual cases where a land location is below sea level, such as Death Valley, California , the elevation AMSL is negative. It is often necessary to compare the local height of the mean sea surface with a "level" reference surface, or geodetic datum, called the geoid . In the absence of external forces, the local mean sea level would coincide with this geoid surface, being an equipotential surface of

1728-416: 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

1800-571: 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

1872-622: The geoid of the Earth, which approximates the local mean sea level for locations in the open ocean. The geoid includes a significant depression in the Indian Ocean , whose surface dips as much as 106 m (348 ft) below the global mean sea level (excluding minor effects such as tides and currents). Precise determination of a "mean sea level" is difficult because of the many factors that affect sea level. Instantaneous sea level varies substantially on several scales of time and space. This

1944-418: The height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,949.903 mi) at the poles and 6,371.001 km (3,958.756 mi) on average. This flattened spheroid , combined with local gravity anomalies , defines

2016-481: 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

2088-407: The 12-month period ending December 31, 2022, the airport had 52,162 flight operations. This included 82% general aviation , 18% air taxi and commercial , and <1% military . This is down from the historical average annual operations in the 1990s of 101,754. Current based aircraft at the airport include 127 aircraft: 92 single-engine and 15 multi-engine airplanes as well as 20 jets . In 2007,

2160-562: The 1690s. Satellite altimeters have been making precise measurements of sea level since the launch of TOPEX/Poseidon in 1992. A joint mission of NASA and CNES , TOPEX/Poseidon was followed by Jason-1 in 2001 and the Ocean Surface Topography Mission on the Jason-2 satellite in 2008. Height above mean sea level ( AMSL ) is the elevation (on the ground) or altitude (in the air) of an object, relative to

2232-973: The 19th century. With high emissions it would instead accelerate further, and could rise by 1.0 m ( 3 + 1 ⁄ 3  ft) or even 1.6 m ( 5 + 1 ⁄ 3  ft) by 2100. In the long run, sea level rise would amount to 2–3 m (7–10 ft) over the next 2000 years if warming stays to its current 1.5 °C (2.7 °F) over the pre-industrial past. It would be 19–22 metres (62–72 ft) if warming peaks at 5 °C (9.0 °F). Rising seas affect every coastal and island population on Earth. This can be through flooding, higher storm surges , king tides , and tsunamis . There are many knock-on effects. They lead to loss of coastal ecosystems like mangroves . Crop yields may reduce because of increasing salt levels in irrigation water. Damage to ports disrupts sea trade. The sea level rise projected by 2050 will expose places currently inhabited by tens of millions of people to annual flooding. Without

2304-539: The Battle Creek area. That year, the county also renovated the terminal, doubling its size and expanding the ramp . Over the next four years, passengers increased from 200,000 to more than 500,000 per annum. In 2011, the Kalamazoo/Battle Creek International Airport was served by two major airlines who fly passengers to major hubs with worldwide connections. There was also a public charter airline operating twice weekly from Kalamazoo to locations in Florida. As of May 2012,

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

In 1997, after Pharmacia & Upjohn moved its North American sales office from Michigan to New Jersey, the company made daily service to New Jersey available to all employees on a 10-seat jet. Pfizer expanded the service after acquiring Pharmacia Corp. in 2003 and based two 36-passenger jets at

It is used for a part of continental Europe and the main part of Africa as the official sea level. Spain uses the reference to measure heights below or above sea level at Alicante , while the European Vertical Reference System is calibrated to the Amsterdam Peil elevation, which dates back to

2664-487: 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 .

2736-481: 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

Furthermore, the airport has used several grants and incentives to attract and retain additional flights and carriers in recent years. The original Kalamazoo terminal was a small building made with scrap materials left over from other local projects. In 1958,

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,

2952-400: The airport today. In 1961, an airport traffic control tower was built and the main runway was extended from 3,900 feet to 5,300. In 1963, an instrument landing system was installed to help during poor weather. In 1977, the runway was further lengthened to 6,500 feet. In 1975, the regional air traffic control facility was moved from Battle Creek to Kalamazoo, and, in 1978, a radar facility

3024-578: The airport was served by two major commercial airlines who fly passengers to three major hubs. The public charter Direct Air was subject to Chapter 7 liquidation on April 12, 2012 and has since ceased all operations. In November 2021, United Airlines announced that it would end service to AZO, effective January 3, 2022. The departure by United left only Delta and American as major airlines with service to Kalamazoo/Battle Creek. In 2022, low-cost airline startup Avelo Airlines started twice-weekly flights between Kalamazoo and Orlando. However, in July 2024,

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

3168-772: The airport. But, in June 2008, the aviation unit was closed after 53 years to save money. The move axed 27 jobs; the aircraft were moved to Trenton, New Jersey . As of April 2009, the hangar and property at the Kalamazoo Airport were up for sale. General aviation aircraft are served by FBOs Duncan Aviation, RAI Jets, the Kalamazoo Pilot Association, and Kalamazoo Aircraft Inc. Besides fuel, these businesses combined offer services such as customer shuttles, aircraft maintenance, private jet charters, and both routine and major maintenance . Flight training

3240-456: The amount of water in the oceans, while the existing seawater also expands with heat. Because most of human settlement and infrastructure was built in response to a more-normalized sea level with limited expected change, populations affected by sea level rise will need to invest in climate adaptation to mitigate the worst effects or, when populations are at extreme risk, a process of managed retreat . The term above sea level generally refers to

3312-413: The carrier terminated this service, citing unprofitability. In the 1970s, there were discussions between North Central Airlines and local city officials about building a new airport to serve Battle Creek and Kalamazoo. Since the two airports are close, it was not economical for the airlines to fully serve both of the airports. They proposed a "Major Jetport" in the Kalamazoo area, which might have become

3384-502: 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

3456-549: The college, but not since May 2006. In the 1970s, private flight training operations were restricted to two local FBOs: Kal Aero and Lakala Aviation. The county government received many complaints about unauthorized lessons from private parties. Upon these reports, the county government added to the flight training ordinance that violators could be fined $ 500, or jailed for 90 days, if found guilty of offering flight lessons illegally. This restriction has since been lifted, but those providing flight instruction must have an agreement with

3528-934: 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

3600-756: The field was licensed as the first municipal airport in Michigan . It was named Lindbergh Field in honor of famous aviator Charles Lindbergh . Airline service came to Kalamazoo in May 1944. Two commuter airlines, Francis Airways and Northern Skyways , provided service to other Michigan cities, then ceased the flights after two years. From 1946 and 1955, several small airlines offered commuter flights to nearby cities. In May 1955, North Central Airlines began daily service to Detroit and Chicago. North Central became Republic Airlines , which merged into Northwest Airlines , which in turn merged into Delta Air Lines – which serves

3672-557: 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

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

3888-482: The geoid is referred to as (mean) ocean surface topography . It varies globally in a typical range of ±1 m (3 ft). Several terms are used to describe the changing relationships between sea level and dry land. The melting of glaciers at the end of ice ages results in isostatic post-glacial rebound , when land rises after the weight of ice is removed. Conversely, older volcanic islands experience relative sea level rise, due to isostatic subsidence from

The resilience and adaptive capacity of ecosystems and countries also varies, which will result in more or less pronounced impacts. The greatest impact on human populations in the near term will occur in the low-lying Caribbean and Pacific islands . Sea level rise will make many of them uninhabitable later this century. Pilots can estimate height above sea level with an altimeter set to

Local mean sea level (LMSL) is defined as the height of the sea with respect to a land benchmark, averaged over a period of time long enough that fluctuations caused by waves and tides are smoothed out, typically a year or more. One must adjust perceived changes in LMSL to account for vertical movements of the land, which can occur at rates similar to sea level changes (millimetres per year). Some land movements occur because of isostatic adjustment to

Changes in ground-based ice volume also affect local and regional sea levels by the readjustment of the geoid and true polar wander . Atmospheric pressure , ocean currents and local ocean temperature changes can affect LMSL as well. Eustatic sea level change (global as opposed to local change)

Soon after the concept failed, most airline service was shifted to Kalamazoo, as the Kalamazoo airport had more passengers and more demand for flights. Kalamazoo/Battle Creek International Airport covers 832 acres (337 ha) at an elevation of 874 feet (266 m) above mean sea level . It has three asphalt runways : 17/35, 6,502 ft × 150 ft (1,982 m × 46 m), 05/23, 3,439 ft × 100 ft (1,048 m × 30 m) and 09/27, 2,800 ft × 60 ft (853 m × 18 m). Present-day taxiways Delta and Alpha were originally runways. For
