ICAO airport code
–
The ICAO airport code or location indicator is a four-character alphanumeric code designating aerodromes around the world. ICAO codes are used to identify other aviation facilities such as weather stations, International Flight Service Stations or Area Control Centers. Flight information regions are identified by a unique ICAO-code. Code selections in North America were based on existing radio station identifiers, for example, radio stations in Canada were already starting with C, so it seemed logical to begin Canadian airport identifiers with Cxxx. The United States had many pre-existing airports with established mnemonic codes and their ICAO codes were formed simply by prepending a K to the existing codes, as half the radio station identifiers in the US began with K. Most ICAO codes outside the US and Canada have a geographical structure. Most of the rest of the world was classified in a more planned top-down manner, thus Uxxx referred to the Soviet Union with the second letter denoting the specific region within it, and so forth. Europe had too many locations for one starting letter, so it was split into Exxx for northern Europe. The second letter was more specific, EGxx was the United Kingdom, EDxx was West Germany, ETxx was East Germany, LExx was Spain, LAxx was Albania, France was designated LFxx, as the counterpart EFxx was the unambiguously northern Finland. ICAO codes are separate and different from IATA codes, which are used for airline timetables, reservations. For example, the IATA code for Londons Heathrow Airport is LHR, in general IATA codes are usually derived from the name of the airport or the city it serves, while ICAO codes are distributed by region and country. Far more aerodromes have ICAO codes than IATA codes, and to add to the confusion IATA codes are assigned to railway stations. Unlike the IATA codes, the ICAO codes generally have a structure and are comprehensive. In general, the first letter is allocated by continent and represents a country or group of countries within that continent, the second letter generally represents a country within that region, and the remaining two are used to identify each airport. The exception to rule is larger countries that have single-letter country codes. In either case, ICAO codes generally provide geographical context unlike IATA codes, for example, if one knows that the ICAO code for Heathrow is EGLL, then one can deduce that the airport EGGP is somewhere in the UK. On the other hand, knowing that the IATA code for Heathrow is LHR does not enable one to deduce the location of the airport LHV with any greater certainty, there are a few exceptions to the regional structure of the ICAO code made for political or administrative reasons. Similarly Saint Pierre and Miquelon is controlled by France, and airports there are assigned LFxx as though they were in Europe, further, in region L, all available 2-letter prefixes have been exhausted and thus no additional countries can be added

Odense
–
Odense is the third-largest city in Denmark. It has a population of 175,245 as of January 2016, by road, Odense is located 45 kilometres north of Svendborg,144 kilometres to the south of Aarhus and 167 kilometres to the southwest of Copenhagen. Odense has close associations with Hans Christian Andersen who is remembered above all for his fairy tales and he was born in the city in 1805 and spent his childhood years there. There has been settlement in the Odense area for over 4,000 years, although the name was not mentioned in writing until 988. Canute IV of Denmark, generally considered to be the last Viking king, was murdered by peasants in Odenses St Albans Priory on 10 July 1086. Although the city was burned in 1249 following a royal rivalry, in 1865, one of the largest railway terminals in Denmark was built, further increasing the population and commerce, and by 1900, Odense had reached a population of 35,000. Odenses Odinstårnet was one of the tallest towers in Europe when built in 1935 but was destroyed by the Nazis during World War II, the University of Southern Denmark was established in 1966. In the present day, Odense remains the hub of Funen. Several major industries are located in the city including the Albani Brewery and GASA, Denmarks major dealer in vegetables, fruits and flowers. In sports, Odense has a number of clubs including OB, BM, B1909, and B1913, the Odense Bulldogs professional ice hockey team. Odense is served by Hans Christian Andersen Airport and Odense station, Odense is one of Denmarks oldest cities. Archaeological excavations in the vicinity show proof of settlement for over 4,000 years since at least the Stone Age, the earliest community was centred on the higher ground between the Odense River to the south and Naesbyhoved Lake to the north. Nonnebakken, one of Denmarks former Viking ring fortresses, lay to the south of the river, today, Odenses Møntergården Museum has many artefacts related to the early Viking history in the Odense area. The Vikings built numerous fortifications along the banks to defend it against invaders coming in from the coast. The first church in Odense appears to have been St Marys, the territory, previously part of the vast Archbishopric of Hamburg, was created a Catholic diocese in 988. The first recorded bishops of Odense were Odinkar Hvide and Reginbert, recent excavations have shown that from the early 11th century, the town developed in the area around Albani Torv, Fisketorvet, Overgade and Vestergade. By 1070, Odense had already grown into a city of stature in Denmark, the priory no longer exists, although a church has been situated on the site since about 900. At the beginning of the 12th century, Benedictine monks from England founded St Canutes Abbey and it was here the English monk Ælnoth wrote Denmarks first literary work, Vita et Passio S. Canuti

Denmark
–
The term Danish Realm refers to the relationship between Denmark proper, the Faroe Islands and Greenland—three countries constituting the Kingdom of Denmark. The legal nature of the Kingdom of Denmark is fundamentally one of a sovereign state. The Faroe Islands and Greenland have been part of the Crown of Denmark since 1397 when the Kalmar Union was ratified, legal matters in The Danish Realm are subject to the Danish Constitution. Beginning in 1953, state law issues within The Danish Realm has been governed by The Unity of the Realm, a less formal name for The Unity of the Realm is the Commonwealth of the Realm. In 1978, The Unity of The Realm was for the first time referred to as rigsfællesskabet. The name caught on and since the 1990s, both The Unity of The Realm and The Danish Realm itself has increasingly been referred to as simply rigsfællesskabet in daily parlance. The Danish Constitution stipulates that the foreign and security interests for all parts of the Danish Realm are the responsibility of the Danish government, the Faroes received home rule in 1948 and Greenland did so in 1979. In 2005, the Faroes received a self-government arrangement, and in 2009 Greenland received self rule, the Danish Realms unique state of internal affairs is acted out in the principle of The Unity of the Realm. This principle is derived from Article 1 of the Danish Constitution which specifies that constitutional law applies equally to all areas of the Danish Realm, the Constitutional Act specifies that sovereignty is to continue to be exclusively with the authorities of the Realm. The language of Denmark is Danish, and the Danish state authorities are based in Denmark, the Kingdom of Denmarks parliament, with its 179 members, is located in the capital, Copenhagen. Two of the members are elected in each of Greenland and the Faroe Islands. The Government ministries are located in Copenhagen, as is the highest court, in principle, the Danish Realm constitutes a unified sovereign state, with equal status between its constituent parts. Devolution differs from federalism in that the powers of the subnational authority ultimately reside in central government. The Self-Government Arrangements devolves political competence and responsibility from the Danish political authorities to the Faroese, the Faroese and Greenlandic authorities administer the tasks taken over from the state, enact legislation in these specific fields and have the economic responsibility for solving these tasks. The Danish government provides a grant to the Faroese and the Greenlandic authorities to cover the costs of these devolved areas. The 1948 Home Rule Act of the Faroe Islands sets out the terms of Faroese home rule, the Act states. the Faroe Islands shall constitute a self-governing community within the State of Denmark. It establishes the government of the Faroe Islands and the Faroese parliament. The Faroe Islands were previously administered as a Danish county, the Home Rule Act abolished the post of Amtmand and these powers were expanded in a 2005 Act, which named the Faroese home government as an equal partner with the Danish government

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Runway
–
According to the International Civil Aviation Organization, a runway is a defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft. Runways may be a surface or a natural surface. Runways are named by a number between 01 and 36, which is generally the magnetic azimuth of the heading in decadegrees. This heading differs from true north by the magnetic declination. A runway numbered 09 points east, runway 18 is south, runway 27 points west, when taking off from or landing on runway 09, a plane would be heading 90°. A runway can normally be used in both directions, and is named for each separately, e. g. runway 33 in one direction is runway 15 when used in the other. The two numbers usually differ by 18, Runway Zero Three Left becomes Runway Two One Right when used in the opposite direction. In some countries, if parallel runways are too close to each other, at large airports with four or more parallel runways some runway identifiers are shifted by 10 degrees to avoid the ambiguity that would result with more than three parallel runways. For example, in Los Angeles, this results in runways 6L, 6R, 7L. At Dallas/Fort Worth International Airport, there are five parallel runways, named 17L, 17C, 17R, 18L, for clarity in radio communications, each digit in the runway name is pronounced individually, runway three six, runway one four, etc. A leading zero, for example in runway zero six or runway zero one left, is included for all ICAO, however, most U. S. civil aviation airports drop the leading zero as required by FAA regulation. This also includes some military airfields such as Cairns Army Airfield and this American anomaly may lead to inconsistencies in conversations between American pilots and controllers in other countries. It is very common in a such as Canada for a controller to clear an incoming American aircraft to, for example, runway 04. In flight simulation programs those of American origin might apply U. S. usage to airports around the world, for example, runway 05 at Halifax will appear on the program as the single digit 5 rather than 05. Runway designations change over time because the magnetic poles slowly drift on the Earths surface, depending on the airport location and how much drift takes place, it may be necessary over time to change the runway designation. As runways are designated with headings rounded to the nearest 10 degrees, for example, if the magnetic heading of a runway is 233 degrees, it would be designated Runway 23. If the magnetic heading changed downwards by 5 degrees to 228, if on the other hand the original magnetic heading was 226, and the heading decreased by only 2 degrees to 224, the runway should become Runway 22. Because the drift itself is slow, runway designation changes are uncommon

Asphalt
–
Asphalt, also known as bitumen is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in deposits or may be a refined product. Until the 20th century, the term asphaltum was also used, the word is derived from the Ancient Greek ἄσφαλτος ásphaltos. The primary use of asphalt/bitumen is in construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt, the terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, asphalt is the carefully refined residue from the process of selected crude oils. Outside the United States, the product is often called bitumen, geologists often prefer the term bitumen. Common usage often refers to forms of asphalt/bitumen as tar. Naturally occurring asphalt/bitumen is sometimes specified by the crude bitumen. Its viscosity is similar to that of cold molasses while the material obtained from the distillation of crude oil boiling at 525 °C is sometimes referred to as refined bitumen. The Canadian province of Alberta has most of the reserves of natural bitumen, covering 142,000 square kilometres. Additionally, most natural bitumens contain organosulfur compounds, resulting in a sulfur content of up to 4%. Nickel and vanadium are found in the <10 ppm level, as is typical of some petroleum, the substance is soluble in carbon disulfide. It is commonly modelled as a colloid, with asphaltenes as the dispersed phase, and it is almost impossible to separate and identify all the different molecules of asphalt, because the number of molecules with different chemical structure is extremely large. Asphalt/bitumen can sometimes be confused with tar, which is a visually similar black. During the early and mid-20th century when town gas was produced, coal tar was a readily available byproduct, the addition of tar to macadam roads led to the word tarmac, which is now used in common parlance to refer to road-making materials. However, since the 1970s, when natural gas succeeded town gas, other examples of this confusion include the La Brea Tar Pits and the Canadian oil sands, both of which actually contain natural bitumen rather than tar. Pitch is another term used at times to refer to asphalt/bitumen

Poaceae
–
Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses. Poaceae includes the cereal grasses, bamboos and the grasses of natural grassland and cultivated lawns, Grasses have stems that are hollow except at the nodes and narrow alternate leaves borne in two ranks. The lower part of each leaf encloses the stem, forming a leaf-sheath, with ca 780 genera and around 12,000 species, Poaceae are the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. Grasslands such as savannah and prairie grasses are dominant are estimated to constitute 40. 5% of the land area of the Earth, excluding Greenland. Grasses are also an important part of the vegetation in many habitats, including wetlands, forests. Though commonly called grasses, seagrasses, rushes, and sedges fall outside this family, the rushes and sedges are related to the Poaceae, being members of the order Poales, but the seagrasses are members of order Alismatales. The name Poaceae was given by John Hendley Barnhart in 1895, based on the tribe Poeae described in 1814 by Robert Brown, the term is derived from the Ancient Greek πόα. Grasses include some of the most versatile plant life-forms, a cladogram shows subfamilies and approximate species numbers in brackets, Before 2005, fossil findings indicated that grasses evolved around 55 million years ago. Recent findings of grass-like phytoliths in Cretaceous dinosaur coprolites have pushed this back to 66 million years ago. In 2011, revised dating of the origins of the rice tribe Oryzeae suggested a date as early as 107 to 129 Mya, a multituberculate mammal with grass-eating adaptations seems to suggest that grasses were already around at 120 mya. This separation occurred within the short time span of about 4 million years. Grass leaves are always alternate and distichous, and have parallel veins. Each leaf is differentiated into a lower sheath hugging the stem, the leaf blades of many grasses are hardened with silica phytoliths, which discourage grazing animals, some, such as sword grass, are sharp enough to cut human skin. A membranous appendage or fringe of hairs called the ligule lies at the junction between sheath and blade, preventing water or insects from penetrating into the sheath, flowers of Poaceae are characteristically arranged in spikelets, each having one or more florets. The spikelets are further grouped into panicles or spikes, the part of the spikelet that bears the florets is called the rachilla. A spikelet consists of two bracts at the base, called glumes, followed by one or more florets, a floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The flowers are usually hermaphroditic—maize being an important exception—and anemophilous or wind-pollinated, the perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea, these are generally interpreted to be modified sepals. This complex structure can be seen in the image on the right, the fruit of grasses is a caryopsis, in which the seed coat is fused to the fruit wall

Danish language
–
There are also minor Danish-speaking communities in Norway, Sweden, Spain, the United States, Canada, Brazil and Argentina. Due to immigration and language shift in urban areas, around 15–20% of the population of Greenland speak Danish as their home language. Along with the other North Germanic languages, Danish is a descendant of Old Norse, until the 16th century, Danish was a continuum of dialects spoken from Schleswig to Scania with no standard variety or spelling conventions. With the Protestant Reformation and the introduction of printing, a language was developed which was based on the educated Copenhagen dialect. It spread through use in the system and administration though German. Today, traditional Danish dialects have all but disappeared, though there are variants of the standard language. The main differences in language are between generations, with youth language being particularly innovative, Danish has a very large vowel inventory comprising 27 phonemically distinctive vowels, and its prosody is characterized by the distinctive phenomenon stød, a kind of laryngeal phonation type. The grammar is moderately inflective with strong and weak conjugations and inflections, nouns and demonstrative pronouns distinguish common and neutral gender. As in English, Danish only has remnants of a case system, particularly in the pronouns. Its syntax is V2, with the verb always occupying the second slot in the sentence. Danish is a Germanic language of the North Germanic branch, other names for this group are the Nordic or Scandinavian languages. Along with Swedish, Danish descends from the Eastern dialects of the Old Norse language, Scandinavian languages are often considered a dialect continuum, where there are no sharp dividing lines between the different vernacular languages. Like Norwegian and Swedish, Danish was significantly influenced by Low German in the Middle Ages, Danish itself can be divided into three main dialect areas, West Danish, Insular Danish, and East Danish. Danish is largely mutually intelligible with Norwegian and Swedish, both Swedes and Danes also understand Norwegian better than they understand each others languages. By the 8th century, the common Germanic language of Scandinavia, Proto-Norse, had some changes. This language was called the Danish tongue, or Norse language. Norse was written in the alphabet, first with the elder futhark. From the 7th century the common Norse language began to undergo changes that did not spread to all of Scandinavia, most of the changes separating East Norse from West Norse started as innovations in Denmark, that spread through Scania into Sweden and by maritime contact to southern Norway
