National Plan Of Integrated Airport Systems
The National Plan of Integrated Airport Systems (NPIAS) is an inventory of U.S. aviation infrastructure assets. NPIAS was developed and now maintained by the Federal Aviation Administration (FAA). It identifies existing and proposed airports that are significant to national air transportation in the U.S., and thus eligible to receive federal grants under the Airport Improvement Program (AIP). It also includes estimates of the amount of AIP money needed to fund infrastructure development projects that will bring these airports up to current design standards and add capacity to congested airports. The FAA is required to provide Congress with a five-year estimate of AIP-eligible development every two years. The NPIAS contains all commercial service airports, all reliever airports, and selected general aviation General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations with the exception of commercial air ...

Martin 4-0-4
The Martin 4-0-4 was an American pressurized passenger airliner built by the Glenn L. Martin Company. In addition to airline use initially in the United States, it was used by the United States Coast Guard and United States Navy as the RM-1G (later as the VC-3A). Design and development When production of the earlier Martin 2-0-2 was stopped due to problems with wing structural failure the company decided to re-wing an improved version (which had already flown as the Martin 3-0-3). The new aircraft was the Martin 4-0-4. It had structural changes to the wings, pressurization and was lengthened slightly to take 40 passengers. Like the earlier 2-0-2, the 4-0-4 was a cantilever monoplane with a standard tail unit (cantilever tailplane and single vertical stabilizer). It had an airstair in the lower tail section for passenger boarding and disembarkation, retractable tricycle landing gear and was powered by two Pratt & Whitney R-2800-CB16 radial piston engines.

Douglas DC-3
The Douglas DC-3 is a propeller-driven airliner manufactured by Douglas Aircraft Company, which had a lasting effect on the airline industry in the 1930s to 1940s and World War II. It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2. It is a low-wing metal monoplane with conventional landing gear, powered by two radial piston engines of . (Although most DC-3s flying today use Pratt & Whitney R-1830 Twin Wasp engines, many DC-3s built for civil service originally had the Wright R-1820 Cyclone.) The DC-3 has a cruising speed of , a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of , and can operate from short runways. The DC-3 had many exceptional qualities compared to previous aircraft. It was fast, had a good range, was more reliable, and carried passengers in greater comfort. Before the war, it pioneered many air travel routes. It was able to cross the continental United States from New York to Los An ...

Greenville Municipal Airport (Mississippi)
Greenville Municipal Airport is a former airport located 4 miles east-southeast of Greenville, Mississippi. It was closed about 1970 with air service being moved to the Mid Delta Regional Airport. Today it is used a municipal recreation complex known as Washington County Convention Center. History The airport was built about 1942 as an auxiliary airfield for the Army pilot training school at Greenville Army Airfield as part of the 30,000 Pilot Training Program. It had three paved runways, the longest being the northwest/southeast & northeast/southwest runways. It had an aircraft parking ramp but did not have any hangars. After the war ended, the airfield was turned over to the City of Greenville and it became the city municipal airport. Southern Airways began scheduled passenger airline service during the early 1950s with Douglas DC-3 prop aircraft flying daily round trip routings of Memphis - Greenville - Vicksburg - Jackson, MS - Natchez - Baton Rouge - New Orleans a ...

Southern Airways
Southern Airways was a regional airline (known at the time as a "local-service air carrier" as designated by the federal Civil Aeronautics Board) in the United States, from its founding by Frank Hulse in 1949 until 1979, when it merged with North Central Airlines to become Republic Airlines. Southern's corporate headquarters were in Birmingham, with operations headquartered at Hartsfield–Jackson Atlanta International Airport, near Atlanta. History As a local-service airline, Southern Airways covered the south-central U.S. In 1955, their network spanned from Memphis south to New Orleans and east to Charlotte and Jacksonville. In August 1953, Southern flew to 29 airports and in August 1967 to 50. Like other local-service airlines, Southern was subsidized; in 1962, its operating "revenues" of $14.0 million included $5.35 million "Pub. serv. rev." In May 1968, Southern's routes extended from Tri-Cities in Tennessee south to New Orleans and Jacksonville, and east from Baton Ro ...

Jet Aircraft
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved could not begin to be solved until the 1930s. Frank Whittle, an English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military purposes. History After the first instance of powered f ...

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.

Airline
An airline is a company that provides civil aviation, air transport services for traveling passengers and freight. Airlines use aircraft to supply these services and may form partnerships or Airline alliance, alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an Air operator's certificate, air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or Air charter, charter operators. The List of airlines by foundation date, first airline was the German airship company DELAG, founded on November 16, 1909. The four oldest non-airship airlines that still exist are the Netherlands' KLM (1919), Colombia's Avianca (1919), Australia's Qantas (1920) and the Czech Republic's Czech Airlines (1923). Airline ownership has seen a shift from mostly personal ownership until the 1930s to government-ownership of major airlines from the 1940s to ...

General Aviation
General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations with the exception of commercial air transport or aerial work, which is defined as specialized aviation services for other purposes. However, for statistical purposes ICAO uses a definition of general aviation which includes aerial work. General aviation thus represents the "private transport" and recreational components of aviation. Definition The International Civil Aviation Organization (ICAO) defines civil aviation aircraft operations in three categories: General Aviation (GA), Aerial Work (AW) and Commercial Air Transport (CAT). Aerial work operations are separated from general aviation by ICAO by this definition. Aerial work is when an aircraft is used for specialized services such as agriculture, construction, photography, surveying, observation and patrol, search and rescue, and aerial advertisement. However, for statistical purposes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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).

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 ...
