Porterville Army Airfield
Porterville Municipal Airport is a city-owned public-use airport located three nautical miles (6 km) southwest of the central business district of Porterville, a city in Tulare County, California, United States. According to the FAA's National Plan of Integrated Airport Systems for 2009–2013, it is categorized as a ''general aviation'' facility. History The airport was opened in September 1942 as Porterville Army Airfield and was used by the United States Army Air Forces Fourth Air Force as a training base during World War II. It was a sub-base to Lemoore AAF, being used as a pilot training facility. Improvements to the site included a fueling system utilizing nine underground storage tanks. These tanks were filled and abandoned in place. Also located on site are ten fueling pits, which are presently unused. The field had the Air Echelon element from the Western Signal Aviation Unit Training Center at Camp Pinedale. At the end of the war the airfield was determined t ...

Porterville, California
Porterville is a city in the San Joaquin Valley, in Tulare County, California, Tulare County, California, United States. It is part of the Visalia Metropolitan Area, Visalia-Porterville metropolitan statistical area. Since its incorporation in 1902, the city's population has grown as it annexed nearby unincorporated areas. The city's July 2019 population (not including East Porterville, California, East Porterville) was estimated at 59,599. Porterville serves as a gateway to Sequoia National Forest, Giant Sequoia National Monument and Kings Canyon National Park. History During California's Spanish period, the San Joaquin Valley was considered a remote region of little value. Emigrants skirted the eastern foothills in the vicinity of Porterville as early as 1826. Swamps stretched out into the Valley floor lush with tall rushes or "tulare" as the Indigenous people called them. Gold discovered in 1848 brought a tremendous migration to California, and prairie schooners rolled throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
California World War II Army Airfields
During World War II, the United States Army Air Forces (USAAF) established numerous airfields in California 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). However, Air Technical Service Command (ATSC), Air Transport Command (ATC) and I Troop Carrier Command used a significant number of airfields in a support role. A significant number of them had operational squadrons for air defense of the Pacific coastline and anti-submarine patrols, and one was even handed over to Civil Air Patrol pilots for their use. In addition to the major fields, dozens of minor auxiliary fields and airstrips were built, generally to provide more room for basic flight training, but also to support other operations. A few of these were designed as "fallback fields" for launching defensive operations in case of a Japanese invasion. Most Army airfields were built with three runw ...

WestAir
WestAir Commuter Airlines (IATA:OE, VB/ICAO WCA, SDU), was a U.S.-based regional airline formed when Stol Air Commuter changed its name in 1978 to WestAir Airlines; it was renamed WestAir Commuter Airlines in 1986. One of the founders was Maurice J. Gallagher, Jr., who later acquired Allegiant Air. WestAir subsequently became a United Express air carrier via a code sharing agreement with United Airlines. It was headquartered in Fresno, California and was controlled by WestAir Holding, Inc. WestAir was sold to Mesa Air Group in 1992. History Until 1979 Westair had been known as Stol Air Commuter, based in San Rafael, CA with administrative offices in Santa Rosa, CA. It had flown Britten-Norman BN-2 Islanders and Britten-Norman Trislanders. On becoming WestAir in 1978 the WestAir Group then bought Redding, California-based Golden Eagle Airlines, and WestAir began flying that airline's Cessna 402Cs. Turboprop powered de Havilland Canada DHC-6 Twin Otters were added in 1982, Sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultralight
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is installed. The definition means that the aircraft has a slow landing speed and short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Military Aviation
Military aviation comprises military aircraft and other flying machines for the purposes of conducting or enabling aerial warfare, including national airlift ( air cargo) capacity to provide logistical supply to forces stationed in a war theater or along a front. Airpower includes the national means of conducting such warfare, including the intersection of transport and warcraft. Military aircraft include bombers, fighters, transports, trainer aircraft, and reconnaissance aircraft. History The first military uses of aviation involved lighter-than-air balloons. During the Battle of Fleurus in 1794, the French observation balloon ''l'Entreprenant'' 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 airc ...

Air Taxi
An air taxi is a small commercial aircraft that makes short flights on demand. In 2001 air taxi operations were promoted in the United States by a NASA and aerospace industry study on the potential Small Aircraft Transportation System (SATS) and the rise of light-jet aircraft manufacturing. Since 2016, air taxis have reemerged as part of the burgeoning field of eVTOL. Regulation In Canada, air taxi operations are regulated by Transport Canada under Canadian Aviation Regulation 703. The Canadian definition of air taxi includes all commercial single-engined aircraft, multi-engined helicopters flown by visual flight rules by one pilot and all multi-engined, non-turbo-jet aircraft, with a maximum take-off weight or less and nine or fewer passenger seats, that are used to transport people or goods or for sightseeing. In the US, air taxi and air charter operations are governed by 14 CFR Part 135 and 14 CFR part 298 of the Federal Aviation Regulations (FAR).
