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

Teruel
–
Teruel is a town in Aragon, located in eastern Spain, and is also the capital of Teruel Province. It has a population of 35,675 in 2014 making it the least populated provincial capital in the country, Teruel is regarded as the town of mudéjar due to numerous buildings designed in this style. All of them are comprised in the Mudéjar Architecture of Aragon which is a World Heritage Site by the UNESCO, Teruels remote and mountainous location 915 metres above sea level and its low population has led to relative isolation within Spain. A campaign group with the slogan Teruel existe was founded in 1999 to press for recognition and investment in the town. Due in part to the campaign, transport connections to Teruel are being improved with the construction of a motorway between Zaragoza and Sagunto, large parts of which are now open. However, Teruel remains the provincial capital in peninsular Spain without a direct railway link to the capital. According to the Köppen climate classification, Teruel has a humid subtropical bordering on a cold semi-arid climate, summer temperatures are mild, although there is much daily variation, and winters are cold, with low minimum temperatures sometimes dropping to −10 °C. The lowest amount of rainfall is in winter and the greatest falls at the end of spring, the temperature records recorded at the Observatoire de Teruel 40.2 °C on August 10,2012 and −19 °C on December 26,2001. Teruel was founded in 1171 by Alfonso II, in the Middle Ages Teruel possessed a prominent Jewish community, which was robust during the centuries Muslims were in power and enjoyed several privileges. Later on after the Christian reconquest of Spain, the Jewish community paid a tax of 300 sueldos. Its members were engaged in commerce and industry, especially in wool-weaving, during the persecutions of 1391 many of them were killed, while others accepted Christianity in order to save their lives. Teruel was fought over in the Spanish Civil War and suffered much destruction, the Battle of Teruel in December 1937-February 1938, was one of the bloodiest of the war. The town changed several times, first falling to the Republicans. In the course of the fighting, Teruel was subjected to heavy artillery, the two sides suffered up to 140,000 casualties between them in the three-month battle. The Nationalists won a decisive victory, one of Teruels best known monuments is very small statue of a bull on top of a tall column, known as El Torico. It is located in the square, Plaza Carlos Castell. It includes a mausoleum, Mausoleo de Los Amantes, housing the mummified bodies of Isabel de Segura and this story is known as los amantes de Teruel and has inspired writers and an opera composed by Tomás Bretón.

Province of Teruel
–
Teruel is a province of Aragon, in the northeast of Spain. It is bordered by the provinces of Tarragona, Castellón, Valencia, Cuenca, Guadalajara, the area of the province is 14,809 km². Its population is 138,686, of whom about a live in the capital. It contains 236 municipalities, of more than half are villages of under 200 people. The main language throughout the province is Spanish, although Catalan is spoken in the comarca of Matarranya and this province is located in the mountainous Sistema Ibérico area. Most of the Teruel Province has undergone massive depopulation since the middle of the 20th century and this situation is shared with other areas in Spain, particularly with those near the Iberian mountain range and with other areas in Aragón. The exodus from the mountain areas in Teruel rose after General Francos Plan de Estabilización in 1959. As a consequence there are many ghost towns in different parts of the province, a great number of surviving towns in Teruel province have only a residual population, reviving somewhat during the summer when a few city-dwellers spend their holidays there. The Teruel Exists movement began at the turn of the 21st century and it is a platform of provincial authorities, institutions and sympathizers seeking to reverse the long-standing neglect of this province. org Teruel Info. - Caciquismo & desarrollismo – N.

Spain
–
By population, Spain is the sixth largest in Europe and the fifth in the European Union. Spains capital and largest city is Madrid, other urban areas include Barcelona, Valencia, Seville, Bilbao. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago, in the Middle Ages, the area was conquered by Germanic tribes and later by the Moors. Spain is a democracy organised in the form of a government under a constitutional monarchy. It is a power and a major developed country with the worlds fourteenth largest economy by nominal GDP. Jesús Luis Cunchillos argues that the root of the span is the Phoenician word spy. Therefore, i-spn-ya would mean the land where metals are forged, two 15th-century Spanish Jewish scholars, Don Isaac Abravanel and Solomon ibn Verga, gave an explanation now considered folkloric. Both men wrote in two different published works that the first Jews to reach Spain were brought by ship by Phiros who was confederate with the king of Babylon when he laid siege to Jerusalem. This man was a Grecian by birth, but who had given a kingdom in Spain. He became related by marriage to Espan, the nephew of king Heracles, Heracles later renounced his throne in preference for his native Greece, leaving his kingdom to his nephew, Espan, from whom the country of España took its name. Based upon their testimonies, this eponym would have already been in use in Spain by c.350 BCE, Iberia enters written records as a land populated largely by the Iberians, Basques and Celts. Early on its coastal areas were settled by Phoenicians who founded Western Europe´s most ancient cities Cadiz, Phoenician influence expanded as much of the Peninsula was eventually incorporated into the Carthaginian Empire, becoming a major theater of the Punic Wars against the expanding Roman Empire. After an arduous conquest, the peninsula came fully under Roman Rule, during the early Middle Ages it came under Germanic rule but later, much of it was conquered by Moorish invaders from North Africa. In a process took centuries, the small Christian kingdoms in the north gradually regained control of the peninsula. The last Moorish kingdom fell in the same year Columbus reached the Americas, a global empire began which saw Spain become the strongest kingdom in Europe, the leading world power for a century and a half, and the largest overseas empire for three centuries. Continued wars and other problems led to a diminished status. The Napoleonic invasions of Spain led to chaos, triggering independence movements that tore apart most of the empire, eventually democracy was peacefully restored in the form of a parliamentary constitutional monarchy. Spain joined the European Union, experiencing a renaissance and steady economic growth

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

Airbus A340
–
The Airbus A340 is a long-range, four-engine, wide-body commercial passenger jet airliner developed and produced by the European aerospace company Airbus. The A340 was assembled in Toulouse, France and it seats up to 375 passengers in the standard variants and 440 in the stretched -600 series. Depending on the model, it has a range of 6,700 to 9,000 nautical miles and its distinguishing features are four high-bypass turbofan engines and three-bogie main landing gears. The A340 was manufactured in four fuselage lengths, the initial variant, A340-300, which entered service in 1993, measured 63.69 metres. The shorter -200 was developed next, and the A340-600 was a 15.96 metres stretch of the -200, the -600 was developed alongside the shorter A340-500, which would become the longest-range commercial airliner until the arrival of the Boeing 777-200LR. The -200 and -300 models were powered by the 151 kilonewtons CFM56-5C, the initial A340-200 and -300 variants share the fuselage and wing of the twin-engine Airbus A330 with which it was concurrently designed. The heavier A340-500 and -600 are longer and have larger wings, launch customers Lufthansa and Air France placed the A340 into service in March 1993. In September 2011,379 orders had been placed, of which 375 were delivered, the most common type were the A340-300 model, with 218 aircraft delivered. Lufthansa is the biggest operator of the A340, having acquired 59 aircraft, Airbus announced on 10 November 2011 that A340 production had been concluded. When Airbus designed the Airbus A300 during the 1970s, it envisioned a broad family of airliners to compete against Boeing and Douglas, from the moment of formation, Airbus had begun studies into derivatives of the Airbus A300B in support of this long-term goal. Prior to the introduction of the first Airbus airliners, Airbus had identified nine possible variations of the A300 known as A300B1 to B9. A 10th variation, conceived in 1973, later the first to be constructed, was designated the A300B10 and it was a smaller aircraft that would be developed into the long-range Airbus A310. Airbus then focused its efforts on the market, which resulted in the Airbus A320 family. The decision to work on the A320, instead of an aircraft proposed by the Germans. The A300B11, a derivative of the A310, was designed upon the availability of ten ton engines and it would seat between 180 and 200 passengers, and have a range of 6,000 nautical miles. It was deemed the replacement for the less-efficient Boeing 707s and Douglas DC-8s still in service, the A300B11 was joined by another design, the A300B9, which was a larger derivative of the A300. The B9 was developed by Airbus from the early 1970s at a pace until the early 1980s. It was essentially a stretched A300 with the wing, coupled with the most powerful turbofan engine at the time
