United States Army
The United States Army (USA) is the land service branch of the United States Armed Forces. It is one of the eight U.S. uniformed services, and is designated as the Army of the United States in the U.S. Constitution.Article II, section 2, clause 1 of the United States Constitution (1789). See alsTitle 10, Subtitle B, Chapter 301, Section 3001 The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to be th ...

International Air Transport Association
The International Air Transport Association (IATA ) is a trade association of the world's airlines founded in 1945. IATA has been described as a cartel since, in addition to setting technical standards for airlines, IATA also organized tariff conferences that served as a forum for price fixing. Consisting in 2016 of 290 airlines, primarily major carriers, representing 117 countries, the IATA's member airlines account for carrying approximately 82% of total available seat miles air traffic. IATA supports airline activity and helps formulate industry policy and standards. It is headquartered in Canada in the city of Montréal, with executive offices in Geneva, Switzerland. History IATA was formed in April 1945 in Havana, Cuba. It is the successor to the International Air Traffic Association, which was formed in 1919 at The Hague, Netherlands. At its founding, IATA consisted of 57 airlines from 31 countries. Much of IATA's early work was technical and IATA provided input to the ...

Asphalt
Asphalt, also known as bitumen (, ), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used. Full text at Internet Archive (archive.org) The word is derived from the Ancient Greek ἄσφαλτος ''ásphaltos''. The largest natural deposit of asphalt in the world, estimated to contain 10 million tons, is the Pitch Lake located in La Brea in southwest Trinidad (Antilles island located on the northeastern coast of Venezuela), within the Siparia Regional Corporation. The primary use (70%) of asphalt is in Road surface, road construction, where it is used as the glue or binder mixed with construction aggregate, aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. In material sciences an ...

Mean Sea Level
There are several kinds of mean in mathematics Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics ..., especially in statistics. Each mean serves to summarize a given group of data, often to better understand the overall value (magnitude (mathematics), magnitude and sign (mathematics), sign) of a given data set. For a data set, the ''arithmetic mean'', also known as "arithmetic average", is a measure of central tendency of a finite set of numbers: specifically, the sum of the values divided by the number of values. The arithmetic mean of a set of numbers ''x''1, ''x''2, ..., x''n'' is typically denoted using an overhead bar, \bar. If the data set were based on a series of observations obtained by sampling (statistics), sampling from a statistical population, the arithmetic mean is th ...

Elevation
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum). The term ''elevation'' is mainly used when referring to points on the Earth's surface, while ''altitude'' or ''geopotential height'' is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and '' depth'' is used for points below the surface. Elevation is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge, the summits of Mount Everest and Chimborazo have, respectively, the largest elevation and the largest geocentric distance. Aviation In aviation the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliport
A heliport is a small airport suitable for use by helicopters and some other vertical lift aircraft. Designated heliports typically contain one or more touchdown and liftoff areas and may also have limited facilities such as fuel or hangars. In some larger towns and cities, customs facilities may also be available. Early advocates of helicopters hoped that heliports would become widespread, but they have become contentious in urban areas due to the excessive noise caused by helicopter traffic. In American use a heliport is defined as "an area of land, water, or structure used or intended to be used for the landing and takeoff of helicopters and includes its buildings and facilities if any." A heliport will consist of one or more helipads, which are defined as "a small, designated area, usually with a prepared surface, on a heliport, airport, landing/take-off area, apron/ramp, or movement area used for takeoff, landing, or parking of helicopters." In Canada the term heliport i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arizona World War II Army Airfields
During World War II, the United States Army Air Forces (USAAF) established numerous airfields in Arizona for training pilots and aircrews of USAAF fighters and bombers. Most of these airfields were under the command of Fourth Air Force or the Army Air Forces Training Command (AAFTC) (A predecessor of the current-day United States Air Force Air Education and Training Command). However, the other USAAF support commands (Air Technical Service Command (ATSC); Air Transport Command (ATC) or Troop Carrier Command) commanded a significant number of airfields in a support roles. It is still possible to find remnants of these wartime airfields. Many were converted into municipal airports, some were returned to agriculture and several were retained as United States Air Force installations and were front-line bases during the Cold War. Hundreds of the temporary buildings that were used survive today, and are being used for other purposes. Major airfields Air Transport Command * Coolidge A ...

Williams Air Force Base
Williams Air Force Base is a former United States Air Force (USAF) base, located in Maricopa County, Arizona, east of Chandler, and about southeast of Phoenix. It is a designated Superfund site due to a number of soil and groundwater contaminants. It was active as a training base for both the United States Army Air Forces, as well as the USAF from 1941 until its closure in 1993. Williams was the leading pilot training facility of the USAF, supplying 25% of all pilots. Since its closure, the base has largely been annexed by the city of Mesa, Arizona. It was converted into the civilian Williams Gateway Airport, later renamed Phoenix-Mesa Gateway Airport. In recent years, the land has emerged as an educational and industrial campus anchored by Arizona State University Polytechnic Campus and Chandler-Gilbert Community College. History During March 1941, some citizens of Mesa, Arizona, were actively working on obtaining a U.S. Army Air Corps facility located near their city. One ...
