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

Federal Aviation Administration
–
The Federal Aviation Administration of the United States is a national authority with powers to regulate all aspects of civil aviation. The FAAs roles include, Regulating U. S, each LOB has a specific role within the FAA. Airports — plans and develops projects involving airports, overseeing their construction, Air Traffic Organization — primary duty is to safely and efficiently move air traffic within the National Airspace System. ATO employees manage air traffic facilities including Airport Traffic Control Towers, Aviation Safety — Responsible for aeronautical certification of personnel and aircraft, including pilots, airlines, and mechanics. Commercial Space Transportation — ensures protection of U. S. assets during the launch or reentry of commercial space vehicles, the FAA is headquartered in Washington, D. C. as well as the William J. The newly created Aeronautics Branch, operating under the Department of Commerce assumed primary responsibility for aviation oversight, in fulfilling its civil aviation responsibilities, the Department of Commerce initially concentrated on such functions as safety regulations and the certification of pilots and aircraft. It took over the building and operation of the system of lighted airways. The Aeronautics Branch was renamed the Bureau of Air Commerce in 1934 to reflect its status within the Department. As commercial flying increased, the Bureau encouraged a group of airlines to establish the first three centers for providing air traffic control along the airways, in 1936, the Bureau itself took over the centers and began to expand the ATC system. The pioneer air traffic controllers used maps, blackboards, and mental calculations to ensure the separation of aircraft traveling along designated routes between cities. In 1938, the Civil Aeronautics Act transferred the civil aviation responsibilities from the Commerce Department to a new independent agency. The legislation also expanded the role by giving them the authority. President Franklin D. Roosevelt split the authority into two agencies in 1940, the Civil Aeronautics Administration and the Civil Aeronautics Board, CAA was responsible for ATC, airman and aircraft certification, safety enforcement, and airway development. CAB was entrusted with safety regulation, accident investigation, and economic regulation of the airlines, the CAA was part of the Department of Commerce. The CAB was an independent federal agency, on the eve of Americas entry into World War II, CAA began to extend its ATC responsibilities to takeoff and landing operations at airports. This expanded role eventually became permanent after the war, the application of radar to ATC helped controllers in their drive to keep abreast of the postwar boom in commercial air transportation. The approaching era of jet travel, and a series of midair collisions and this legislation gave the CAAs functions to a new independent body, the Federal Aviation Agency. The act transferred air safety regulation from the CAB to the new FAA, the FAAs first administrator, Elwood R. Quesada, was a former Air Force general and adviser to President Eisenhower

Asheville, North Carolina
–
Asheville is a city in and the county seat of Buncombe County, North Carolina, United States. It is the largest city in Western North Carolina, and the 11th largest city in North Carolina, the citys population was 87,236 according to the 2013 estimates. It is the city in the four-county Asheville metropolitan area. Asheville is home to the United States National Climatic Data Center, before the arrival of the Europeans, the land where Asheville now exists lay within the boundaries of the Cherokee Nation. In 1540, Spanish explorer Hernando de Soto came to the area, bringing the first European visitors along with European diseases, the area was used as an open hunting ground until the middle of the 19th century. The history of Asheville, as a town, began in 1784, in that year, Colonel Samuel Davidson and his family settled in the Swannanoa Valley, redeeming a soldiers land grant from the state of North Carolina. Soon after building a log cabin at the bank of Christian Creek, Davidson was lured into the woods by a band of Cherokee hunters, Davidsons wife, child and female slave fled on foot overnight to Davidsons Fort 16 miles away. In response to the killing, Davidsons twin brother Major William Davidson and brother-in-law Colonel Daniel Smith formed an expedition to retrieve Samuel Davidsons body and avenge his murder. Months after the expedition, Major Davidson and other members of his family returned to the area. The United States Census of 1790 counted 1,000 residents of the area, Buncombe County was officially formed in 1792. The county seat, named Morristown in 1793, was established on a plateau where two old Indian trails crossed, in 1797, Morristown was incorporated and renamed Asheville after North Carolina Governor Samuel Ashe. For a time, an Enfield rifle manufacturing facility was located in the town, in late April 1865 troops under the overall command of Union Gen. Stoneman captured Asheville. Hartley, Stonemans Raid, p.362 After a negotiated departure, the years following the war were a time of economic and social hardship in Buncombe County, as throughout most of the defeated South. On October 2,1880, the Western North Carolina Railroad completed its line from Salisbury to Asheville, almost immediately it was sold and resold to the Richmond and Danville Railroad Company, becoming part of the Southern Railway in 1894. With the completion of the first railway, Asheville experienced a slow but steady growth as industrial plants increased in number and size, textile mills were established and plants were set up for the manufacture of wood and mica products, foodstuffs, and other commodities. The 21-mile distance between Hendersonville and Asheville of the former Asheville and Spartanburg Railroad was completed in 1886, by that point, the line was operated as part of the Richmond and Danville Railroad until 1894 and controlled by the Southern Railway afterward. Asheville had the first electric railway lines in the state of North Carolina. These would be replaced by buses in 1934, Asheville prospered in the decades of the 1910s and 1920s and at one point was the third largest city in the state, behind Charlotte and Wilmington

Focus city
–
In the airline industry, a focus city is a destination from which an airline operates several point-to-point routes. Thus, a city primarily caters to the local market rather than to connecting passengers. However, with the terms expanded usage, a city may also function as a small-scale hub. Allegiant Air, JetBlue and Frontier Airlines are examples of airlines that consider some of their destinations to be focus cities

Allegiant Air
–
Allegiant Air is an American low-cost airline owned by Allegiant Travel Co. that operates scheduled and charter flights. Allegiant Travel Company is a traded company with 2,848 employees. The corporate headquarters are in Summerlin, Nevada, a suburb of Las Vegas, wholly owned by Allegiant Travel, the airline has over 2,800 employees. Allegiant Air was founded in January 1997 by Mitch Allee, Jim Patterson and Dave Beadle, the airline also has authority for charter service to Canada and Mexico. However, Allegiant was unable to bring in revenue to cover its costs and on December 13,2000. The bankruptcy allowed Maurice J. Gallagher, Jr. one of the major creditors. A veteran leader of low-cost airlines, Gallagher had worked with WestAir and as CEO of ValuJet Airlines, in June 2001, Gallagher restructured Allegiant to a low-cost model, focusing on smaller markets that larger airlines did not serve with mainline aircraft. Now chief executive officer and chairman, he moved the headquarters, in March 2002, Allegiant exited bankruptcy and entered into a long-term contract with Harrahs to provide charter services to its casinos in Laughlin and Reno, Nevada. At the same time, the airline acquired its first McDonnell Douglas MD-80 jetliner, from 2002 through 2004, the airline developed its scheduled-service business model. By 2004, Allegiant was flying from 13 small cities to Las Vegas offering bundled air, in November 2006, Allegiant filed a registration statement with the Securities and Exchange Commission in anticipation of a planned initial public offering of its Common Stock. It is listed on the NASDAQ Stock Market under the ticker symbol ALGT, the airport announced a 10, 000-square-foot expansion in August 2008, which increased the number of gates from two to four and allowed Allegiant to triple the number of flights from Phoenix. The expansion was funded by a loan from Allegiant which will be repaid by passenger fees, on November 14,2007, Allegiant opened its fifth focus city and operations base at Fort Lauderdale-Hollywood International Airport, connecting other Allegiant cities to South Florida. In January 2008, Allegiant opened its base at Washingtons Bellingham International Airport. The airline bases two McDonnell Douglas MD-80 aircraft in Bellingham as part of the expansion, routes served exclusively from Bellingham include Las Vegas, Palm Springs, San Diego, San Francisco and Phoenix. Expansion in Bellingham has been driven by its proximity to Vancouver. On July 1,2010 Allegiant returned to Long Beach Airport in Long Beach, California having previously served LGB with DC-9 jets with nonstop flights to Las Vegas, in February 2010, Allegiant opened its ninth base at Grand Rapids Gerald R. Ford International Airport in Michigan. The airline based two McDonnell Douglas MD-80 aircraft in Grand Rapids, but ended their airports status as a hub in 2011, the airline continues to fly out of Grand Rapids in a reduced capacity. In March 2010, Allegiant purchased six used Boeing 757-200 jetliners as part of plans to begin flights to Hawaii, with deliveries from early 2010 to the fourth quarter of 2011

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

Airspace class (United States)
–
This article describes the implementation of International Civil Aviation Organization airspace classes in the United States of America. For a general discussion of airspace classes, see Airspace class, the Albert ROPER implementation of International Civil Aviation Organization airspace classes defines classes A through G. The other U. S. implementations are described below, the United States also defines categories of airspace that may overlap with classes of airspace. Classes of airspace are mutually exclusive, thus, airspace can be class E and restricted at the same time, but it cannot be both class E and class B at the same location and at the same time. Note, All airspace classes except class G require air traffic control clearance for instrument flight rules operations, in the U. S. airspace is categorized as regulatory and non regulatory. Within these categories exist, controlled and uncontrolled airspace, based on air traffic control service is provided to IFR flights. Class F is not used in the U. S, besides controlled and uncontrolled airspace, other types of airspace include special use and other airspace. Class A airspace extends from 18,000 feet mean sea level MSL to FL600 throughout the continental United States and Alaska. Unless otherwise authorized by ATC, all operations in class A airspace must be under ATC control. An example of an exception to IFR-only flight in this airspace is the use of wave windows and these specific airspace blocks may be opened by ATC to allow sailplanes to fly in the lee waves of mountains. Since class A airspace is restricted to instrument flight only. Class B airspace is defined around key airport traffic areas, usually surrounding the busiest airports in the US according to the number of IFR operations. Each shelf is larger than the one beneath it, many class B airspaces diverge from this model to accommodate traffic patterns or local topological or other features. The upper limit of class B airspace is normally 10,000 feet MSL, All aircraft entering class B airspace must obtain ATC clearance prior to entry and must be prepared for denial of clearance. Visual flight rules flights may proceed under their own navigation after obtaining clearance, some class B airspaces include special transition routes for VFR flight that require communication with ATC but may not require an explicit clearance. Other class B airspaces include VFR corridors through which VFR flights may pass without clearance, VFR flights operating in class B airspace must have three miles of visibility and must remain clear of clouds. Class B airspace has the most stringent rules of all the airspaces in the United States, Class B has strict rules on pilot certification. Pilots operating in class B airspace must have a pilots certificate

North Carolina
–
North Carolina is a state in the southeastern region of the United States. The state borders South Carolina and Georgia to the south, Tennessee to the west, Virginia to the north, North Carolina is the 28th most extensive and the 9th most populous of the U. S. states. The state is divided into 100 counties, the most populous municipality is Charlotte, which is the second largest banking center in the United States after New York City. The state has a range of elevations, from sea level on the coast to 6,684 feet at Mount Mitchell. The climate of the plains is strongly influenced by the Atlantic Ocean. Most of the falls in the humid subtropical climate zone. More than 300 miles from the coast, the western, mountainous part of the state has a highland climate. North Carolina is bordered by South Carolina on the south, Georgia on the southwest, Tennessee on the west, Virginia on the north, the United States Census Bureau places North Carolina in the South Atlantic division of the southern region. So many ships have been lost off Cape Hatteras that the area is known as the Graveyard of the Atlantic, the most famous of these is the Queen Annes Revenge, which went aground in Beaufort Inlet in 1718. The coastal plain transitions to the Piedmont region along the Atlantic Seaboard fall line, the Piedmont region of central North Carolina is the states most populous region, containing the six largest cities in the state by population. It consists of rolling countryside frequently broken by hills or low mountain ridges. The Piedmont ranges from about 300 feet in elevation in the east to about 1,500 feet in the west, the western section of the state is part of the Appalachian Mountain range. Among the subranges of the Appalachians located in the state are the Great Smoky Mountains, Blue Ridge Mountains, the Black Mountains are the highest in the eastern United States, and culminate in Mount Mitchell at 6,684 feet, the highest point east of the Mississippi River. North Carolina has 17 major river basins, the five basins west of the Blue Ridge Mountains flow to the Gulf of Mexico, while the remainder flow to the Atlantic Ocean. Of the 17 basins,11 originate within the state of North Carolina, but only four are contained entirely within the states border – the Cape Fear, the Neuse, the White Oak, and the Tar-Pamlico basin. Elevation above sea level is most responsible for temperature change across the state, the climate is also influenced by the Atlantic Ocean and the Gulf Stream, especially in the coastal plain. These influences tend to cause warmer winter temperatures along the coast, the coastal plain averages around 1 inch of snow or ice annually, and in many years, there may be no snow or ice at all. North Carolina experiences severe weather in summer and winter, with summer bringing threat of hurricanes, tropical storms, heavy rain

McDonnell Douglas MD-80
–
The McDonnell Douglas MD-80 is a series of twin-engine, short- to medium-range, single-aisle commercial jet airliners. It was lengthened and updated from the DC-9 and this series can seat from 130 to 172 passengers depending on variant and seating configuration. The MD-80 series was introduced into service on October 10,1980 by Swissair. The series includes the MD-81, MD-82, MD-83, MD-87 and these all have the same fuselage length except the shortened MD-87. The series was followed into service in modified form by the MD-90 in 1995, Douglas Aircraft developed the DC-9 in the 1960s as a short-range companion to their larger DC-8. The DC-9 was a design, using two rear fuselage-mounted turbofan engines, and a T-tail. The DC-9 has a fuselage design with five-abreast seating, and holds 80 to 135 passengers depending on seating arrangement. The development of MD-80 series began in the 1970s as a lengthened, growth version of the DC-9-50, with a higher maximum take-off weight and a higher fuel capacity. Availability of newer versions of the Pratt & Whitney JT8D engine with higher bypass ratios drove early studies including designs known as Series 55, Series 50, the design effort focused on the Series 55 in August 1977. With the projected entry into service in 1980, the design was marketed as the DC-9 Series 80, Swissair launched the Series 80 in October 1977 with an order for 15 plus an option for five. The MD-80 is a mid-size, medium-range airliner, the series featured a fuselage 14 ft 3 in longer than the DC-9-50. The DC-9s wing design was enlarged by adding sections at the wing root, the initial Series 80 first flew October 19,1979. It was certified as a version of the DC-9 and it was the second generation of the DC-9, originally called the DC-9-80 and the DC-9 Super 80. The design was the generation of the DC-9 with two rear fuselage-mounted turbofan engines, small, highly efficient wings, and a T-tail. The aircraft has distinctive five-abreast seating in the coach class, the aircraft series was designed for frequent, short-haul flights for 130 to 172 passengers depending on plane version and seating arrangement. The MD-80 series aircraft also have longer fuselages than their earlier DC-9 counterparts, some customers, such as American Airlines, still refer to the planes in fleet documentation as Super 80. This model is still flown extensively by American Airlines and Delta Air Lines, comparable airliners to the MD-80 series include the Boeing 737-400 and Airbus A320. The first MD-80, DC-9 line number 909, made its first flight on October 19,1979, the flight-testing leading up to certification had involved three aircraft accumulating a total of 1,085 flying hours on 795 flights

Delta Air Lines
–
Delta Air Lines, Inc. is a major American airline, with its headquarters and largest hub at Hartsfield–Jackson Atlanta International Airport in Atlanta, Georgia. Regional service is operated under the brand name Delta Connection, One of the five remaining legacy carriers, Delta is the sixth-oldest operating airline by foundation date, and the oldest airline still operating in the United States. The companys history can be traced back to Huff Daland Dusters, founded in 1924 in Macon, Georgia as a crop dusting operation. The company moved to Monroe, Louisiana, and was later renamed Delta Air Services, in reference to the nearby Mississippi Delta region, among predecessors of todays Delta Air Lines, Western Airlines and Northwest Airlines began flying passengers in 1926 and 1927, respectively. In 2013, Delta Air Lines was the worlds largest airline in terms of scheduled passengers carried, Delta Air Lines began as a crop dusting operation called Huff Daland Dusters, Incorporated. The company was founded on May 30,1924 in Macon, Georgia and they flew a Huff-Daland Duster, the first true crop duster, designed to combat the boll weevil infestation of cotton crops. Collett E. Woolman, one of the directors, purchased the company on September 13,1928. Service began on June 17,1929 with the flight between Dallas, Texas and Jackson, Mississippi. Delta moved its headquarters to its current location in Atlanta in 1941, and continued to grow through the addition of routes and they replaced propeller planes with jets in the 1960s and entered international competition to Europe in the 1970s and across the Pacific in the 1980s. Deltas more recent history is marked by its emergence from bankruptcy on April 25,2007, the merger was announced April 14,2008, and was set to create the worlds largest airline. After approval of the merger on October 29,2008, Northwest continued to operate as an owned subsidiary of Delta until December 31,2009 when both carriers operating certificates were merged. Delta completed the integration with Northwest on January 31,2010 when their reservation systems and websites were combined, Delta Air Lines as it exists today is the result of numerous mergers over its history. Predecessor carriers forming the current Delta Air Lines include, Chicago, Delta flew under the carrier name of Delta-C&S for the following two years. After successfully introducing 50-seat planes into the United States, it was acquired by Delta in October 1999, Comair became the main carrier of Delta Connection and operated over 400 daily flights from Cincinnati/Northern Kentucky International Airport throughout the U. S. Mexico, and Caribbean. Comair ceased operations on September 29,2012, and was folded into Delta Connection operations, Delta Express began service in October 1996 in an attempt by Delta to compete with low cost airlines on leisure-oriented routes. Its main base of operations was Orlando International Airport and it used Boeing 737–200 aircraft and it ceased operations in November 2003 after Song was established. Song began service on April 15,2003 as an airline operated by Delta to compete directly with JetBlue Airways from both airlines hub at New York–JFK. While the brand was considered an addition to the Northeast-to-Florida market

Airbus A319
–
The Airbus A319 is a member of the Airbus A320 family of short- to medium-range, narrow-body, commercial passenger twin-engine jet airliners manufactured by Airbus. The A319 carries up to 160 passengers and has a range of 3,700 nmi. Final assembly of the takes place in Hamburg, Germany and Tianjin. The A319 is a variant of the Airbus A320 and entered service in April 1996 with Swissair. The aircraft shares a type rating with all other Airbus A320 family variants. As of 28 February 2017, a total of 1,457 Airbus A319 aircraft have been delivered, in addition, another 21 airliners are on firm order. As of 28 February 2017, EasyJet was the largest operator of the Airbus A319, in December 2010, Airbus announced a new generation of the A320 family, the A320neo. The similarly shortened fuselage A319neo variant offers new, more efficient engines, combined with airframe improvements, the aircraft will deliver fuel savings of up to 15%. The first member of the A320 family was the A320 which was launched in March 1984, the family was extended to include the stretched A321, the shortened A319, and the further shortened A318. The A320 family pioneered the use of digital fly-by-wire flight control systems, as well as side stick controls, the A319 was developed at the request of Steven Udvar-Hazy, the former president and CEO of ILFC according to The New York Times. The A319 design is a shortened fuselage, minimum change derivative of the A320 with its origins in the 130- to 140-seat SA1, the SA1 was shelved as the consortium concentrated on its bigger siblings. After healthy sales of the A320/A321, Airbus re-focused on what was known as the A320M-7. It would provide competition for the 737–300/-700. The shrink was achieved through the removal of four frames fore. Consequently, the number of overwing exits was reduced from four to two, the bulk-cargo door was replaced by an aft container door, which can take in reduced height LD3-45 containers. Minor software changes were made to accommodate the different handling characteristics, power is provided by the CFM56-5A or V2500-A5, derated to 98 kN, with option for 105 kN thrust. With virtually the same capacity as the A320-200, and fewer passengers. The A319s wingspan is longer than the overall length

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

General aviation is the term for all civil aviation operations other than scheduled air services and non-scheduled air transport operations for remuneration or hire. General aviation flights range from gliders and powered parachutes to corporate business jet flights, the majority of the worlds air traffic falls into this category, and most of the worlds airports serve general aviation exclusively. General aviation covers a range of activities, both commercial and non-commercial, including flying clubs, flight training, agricultural aviation, light aircraft manufacturing. Of the 21,000 civil aircraft registered in the UK,96 per cent are engaged in GA operations, there are 28,000 Private Pilot Licence holders, and 10,000 certified glider pilots. Some of the 19,000 pilots who hold professional licences are also engaged in GA activities, GA operates from more than 1,800 airports and landing sites or aerodromes, ranging in size from large regional airports to farm strips. GA is regulated by the Civil Aviation Authority, although regulatory powers are being transferred to the European Aviation Safety Agency. The main focus is on standards of airworthiness and pilot licensing, general aviation is particularly popular in North America, with over 6,300 airports available for public use by pilots of general aviation aircraft. In comparison, scheduled flights operate from around 560 airports in the U. S, aircraft Owners and Pilots Association, general aviation provides more than one percent of the United States GDP, accounting for 1.3 million jobs in professional services and manufacturing. Most countries have authorities that oversee all civil aviation, including general aviation, Aviation accident rate statistics are necessarily estimates. In Canada, recreational flying accounted for 0.7 fatal accidents for every 1000 aircraft, while air taxi accounted for 1.1 fatal accidents for every 100,000 hours

Airline
–
An airline is a company that provides air transport services for traveling passengers and freight. Airlines utilize aircraft to supply services and may form partnerships or alliances with other airlines for codeshare agreements. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body, Airlines vary in size, from small domestic airlines to full-service international airlines. Airline services can be categorized as being intercontinental, domestic, regional, or international, the largest airline currently is American Airlines Group. DELAG, Deutsche Luftschiffahrts-Aktiengesellschaft was the worlds first airline and it was founded on November 16,1909 with government assistance, and operated airships manufactured by The Zeppelin Corporation. The first fixed wing scheduled air service was started on January 1,1914 from St. Petersburg, Florida to Tampa, the four oldest non-dirigible airlines that still exist are Netherlands KLM, Colombias Avianca, Australias Qantas, and the Czech Republics Czech Airlines. The earliest fixed wing airline in Europe was the Aircraft Transport and Travel, using a fleet of former military Airco DH. 4A biplanes that had been modified to carry two passengers in the fuselage, it operated relief flights between Folkestone and Ghent. On 15 July 1919, the company flew a proving flight across the English Channel, flown by Lt. H Shaw in an Airco DH.9 between RAF Hendon and Paris - Le Bourget Airport, the flight took 2 hours and 30 minutes at £21 per passenger. On 25 August 1919, the company used DH. 16s to pioneer a regular service from Hounslow Heath Aerodrome to Le Bourget, the airline soon gained a reputation for reliability, despite problems with bad weather and began to attract European competition. In November 1919, it won the first British civil airmail contract, six Royal Air Force Airco DH. 9A aircraft were lent to the company, to operate the airmail service between Hawkinge and Cologne. In 1920, they were returned to the Royal Air Force, the first French airline was Société des lignes Latécoère, later known as Aéropostale, which started its first service in late 1918 to Spain. The first German airline to use heavier than air aircraft was Deutsche Luft-Reederei established in 1917 which started operating in February 1919, in its first year, the D. L. R. Operated regularly scheduled flights on routes with a length of nearly 1000 miles. Network was more than 3000 km long, and included destinations in the Netherlands, Scandinavia, another important German airline was Junkers Luftverkehr, which began operations in 1921. It was a division of the aircraft manufacturer Junkers, which became a company in 1924. It operated joint-venture airlines in Austria, Denmark, Estonia, Finland, Hungary, Latvia, Norway, Poland, Sweden, the Dutch airline KLM made its first flight in 1920, and is the oldest continuously operating airline in the world. Established by aviator Albert Plesman, it was awarded a Royal predicate from Queen Wilhelmina. Its first flight was from Croydon Airport, London to Amsterdam, using a leased Aircraft Transport and Travel DH-16, in 1921, KLM started scheduled services

Military aviation
–
Airpower includes the national means of conducting such warfare, including the intersection of transport and war craft. Military aircraft include bombers, fighters, transports, trainer aircraft, the first military uses of aviation involved lighter-than-air balloons. During the Battle of Fleurus in 1794, the French observation balloon lEntreprenant was used to monitor Austrian troop movements, the use of lighter-than-air aircraft in warfare became prevalent in the 19th century, including regular use in the American Civil War. Lighter-than-air military aviation persisted until shortly after World War II, gradually being withdrawn from various roles as heavier-than-air aircraft improved, heavier-than-air aircraft were recognized as having military applications early on, despite resistance from traditionalists and the severe limitations of early aircraft. The U. S. Army Signal Corps purchased a Wright Model A on 2 August 1909 which became the first military aircraft in history, in 1911, the Italians used a variety of aircraft types in reconnaissance, photo-reconnaissance, and bombing roles during the Italo-Turkish War. The Turks, lacking anti-aircraft weapons, were the first to shoot down an aeroplane by rifle fire, technological improvements were made at a frenzied pace, and the first all-metal cantilevered airplanes were going into service as the war ended. The Allies would later use rocket-equipped fighters in the role, immobilizing German armored divisions during the Battle of Normandy. This played a role in winning the Battle of the Atlantic. The introduction of the jet engine, radar, early missiles, helicopters, post World War II, the development of military aviation was spurred by the Cold War stand-off between the super-powers. In the early 1960s, missiles were expected to replace manned interceptors, missiles were also expensive, especially against low-value ground targets. The 1970s saw the return of the fighter, and a greater emphasis on maneuverability. The 1980s through to the present day were characterized by stealth technology, airborne Early Warning provides advance warning of enemy activities to reduce the chance of being surprised. Many also have functions that allow them to direct or vector friendly fighters onto incoming bogeys. Bombers are capable of carrying payloads of bombs and may sacrifice speed or maneuverability to maximize payload. Experimental aircraft are designed to test advanced aerodynamic, structural, avionic and these are usually well instrumented, with performance data telemetered on radio-frequency data links to ground stations located at the test ranges where they are flown. Fighters establish and maintain air superiority, speed and maneuverability are usually requirements and they carry a variety of weapons, including machine guns and guided missiles, to do this. Forward Air Control directs close air support aircraft to ensure that the targets are nullified. Ground-attack aircraft support ground troops by weakening or nullifying enemy defenses, helicopter gunships and specialized ground attack aircraft attack enemy armor or troops and provide close air support for ground troops

Jet aircraft
–
A jet aircraft is an aircraft propelled by jet engines. Jet aircraft generally cruise at faster than about M0.8 at altitudes around 10, Frank Whittle, an English inventor and RAF officer, developed the concept of the jet engine in 1928, and Hans von Ohain in Germany developed the concept independently in the early 1930s. He wrote in February 1936 to Ernst Heinkel, who led the construction of the worlds first turbojet aircraft, however, it can be argued that the English engineer A. A. Griffith, who published a paper in July 1926 on compressors and turbines, also deserves credit. After the first instance of powered flight, large number of jet powerplants were suggested, rené Lorin, Morize, Harris proposed systems for creating a jet efflux. Rocket-powered jet aircraft were pioneered in Germany, the first aircraft to fly under rocket power was the Lippisch Ente, in 1928. The Ente had previously flown as a glider. The next year, in 1929, the Opel RAK.1 became the first purpose-built rocket plane to fly, the turbojet, was invented in the 1930s, independently by Frank Whittle and later Hans von Ohain. The first turbojet aircraft to fly was the Heinkel He 178 V1 first prototype of the German Air Force, the first flight of a jet engined aircraft to come to popular attention was the Italian Caproni Campini N.1 motorjet prototype that flew on August 27,1940. It was the first jet aircraft recognised by the Fédération Aéronautique Internationale, Campini had proposed the motorjet in 1932. The British experimental Gloster E. 28/39 first took to the air on May 15,1941, the United States produced the Bell XP-59A using two examples of a version of the Whittle engine built by General Electric, which flew on October 1,1942. The Meteor was the first production jet as it entered production a few months before the Me 262, which itself had been in development since before the start of the war as Projekt 1065. The first operational jet fighter was the Messerschmitt Me 262, made by Germany during World War II and it was the fastest conventional aircraft of World War II – although there were faster aircraft propelled by unconventional means, such as the rocket-powered Messerschmitt Me 163 Komet. USSR tested its own Bereznyak-Isayev BI-1 in 1942, but the project was scrapped by Joseph Stalin in 1945. The Imperial Japanese Navy also developed jet aircraft in 1945, including the Nakajima J9Y Kikka, a modified, and slightly smaller version of the Me 262 that had folding wings. By the end of 1945, the US had introduced their next jet fighter, the Lockheed P-80 Shooting Star into service and the UK its second fighter design, the US introduced the North American B-45 Tornado, their first jet bomber, into service in 1948. Although capable of carrying nuclear weapons it was used for reconnaissance over Korea, the UK put the English Electric Canberra into service in 1951 as a light bomber. It was designed to fly higher and faster than any interceptor, BOAC operated the first commercial jet service, from London to Johannesburg, in 1952 with the de Havilland Comet jetliner. This highly innovative aircraft travelled far faster and higher than the aircraft, was much quieter, smoother
