Elevation
The elevation of a geographic location (geography), ''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 equipotential surface, surface (see Geodetic datum#Vertical datum, 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 ''three-dimensional space, 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 (volcano), Chimborazo have, respectively, the largest elevation and the largest ECEF, geocentric distance. Aviation In aviation, the term ''elevation'' or ''aerodrome elevation'' is defined by the IC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airports In The Aleutians West Census Area, Alaska
An airport is an aerodrome with extended facilities, mostly for commercial air transport. They usually consist of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Airport operations are extremely complex, with a complicated system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Airports In Alaska
This is a list of airports in Alaska (a U.S. state), grouped by type and sorted by location. It contains all public-use and military airports in the state. Some private-use and former airports may be included where notable, such as airports that were previously public-use, those with commercial enplanements recorded by the FAA or airports assigned an IATA airport code. Due to the small population combined with the large area of the state, much of which is wilderness, most of Alaska is both uninhabited and almost entirely undeveloped. This leads to many towns with no roads leading to them, which are only accessible by airplane (although many coastal villages are also accessible by ship, they nonetheless do not contain any roads accessible by the rest of North America). Because of this, virtually every town in Alaska has an airport. This leads to Alaska having by far the most airports in the country per capita, containing roughly 1 out of every 400 Americans but nearly 1 out of eve ...

Douglas C-47A
The Douglas C-47 Skytrain or Dakota ( RAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II. During the war the C-47 was used for troop transport, cargo, paratrooper, for towing gliders and military cargo parachute drops. The C-47 remained in front-line service with various military operators for many years.Parker 2013, pp. 13, 35, 37, 39, 45–47. It was produced in approximately triple the numbers as the larger, much heavier payload Curtiss C-46 Commando, which filled a similar role for the U.S. military. Approximately 100 countries' armed forces have operated the C-47 with over 60 variants of the aircraft produced. As with the civilian DC-3, the C-47 remains in service, over 80 years after the type's introduction. Design and development The C-47 differed from the civilian DC-3 by way of numerous modifications, including being fitted with a cargo door, hoist attachmen ...

Reeve Aleutian Airways
Reeve Aleutian Airways was an airline headquartered in Anchorage, Alaska, Anchorage, Alaska, United States. It ceased operations on December 5, 2000. Reeve Aleutian was named, possibly as a pun on the word revolution, by combining founder Robert Campbell Reeve, Robert C. Reeve's surname and the Aleutian Islands, its primary destination. History Founding In February 1946, Robert Campbell Reeve, Bob Reeve received a call informing him that some ex-USAAF Douglas C-47 Skytrain, C-47s and Douglas DC-3s were for sale (the C-47 being the military version of the DC-3). Reeve bought his first DC-3 for $20,000 with $3,000 down and the balance payable over 3 years. The cost of conversion to civilian standard was quoted at $50,000, but Reeve did the work himself at a cost of $5,000. A strike by sailors on steamships operating between Seattle and Anchorage started on April 6, 1946. Reeve, along with Merritt Boyle and Bill Borland began flying between Seattle and Anchorage, with stops at Jun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Later this mask became t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravel
Gravel () is a loose aggregation of rock fragments. Gravel occurs naturally on Earth as a result of sedimentation, sedimentary and erosion, erosive geological processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by grain size, particle size range and includes size classes from granule (geology), granule- to boulder-sized fragments. In the grain size, Udden-Wentworth scale gravel is categorized into granular gravel () and pebble gravel (). ISO 14688 grades gravels as fine, medium, and coarse, with ranges for fine and for coarse. One cubic metre of gravel typically weighs about , or one cubic yard weighs about . Gravel is an important commercial product, with a number of applications. Almost half of all gravel production is used as construction aggregate, aggregate for concrete. Much of the rest is used for road construction, either in the road base or as the road surface (with or without bitumen, asphalt or other binders.) Natu ...

Runway
In aviation, a runway is an elongated, rectangular surface designed for the landing and takeoff of an aircraft. Runways may be a human-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to manufacture Bréguet Aviation military aircraft. In January 1919, aviation p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
