Mail Plane
A mail plane is an aircraft used for carrying mail. Aircraft that were purely mail planes existed almost exclusively prior to World War II. Because early aircraft were too underpowered to carry cargoes, and too costly to run any "economy class" passenger-carrying service, the main civilian role for aircraft was to carry letters faster than previously possible. In 1934, some mail services in the USA were operated by the United States Army Air Corps, soon ending in the Air Mail scandal. In the past, mail-carrying aircraft had to carry a special official emblem on the fuselages; in case of British-registered aircraft, a special ''Royal Air Mail pennant'' (a blue triangular flag with a crowned bugle emblem in yellow and the letters "ROYAL AIR MAIL" in white) would sometimes be flown as well. From the late 1940s, mail planes became increasingly rare, as the increasing size of aircraft and economics dictated a move towards bulk carriage of mail onboard airline flights, and this rema ...

Cessna 208
The Cessna 208 Caravan is a utility aircraft produced by Cessna. The project was commenced on November 20, 1981, and the prototype first flew on December 9, 1982. The production model was certified by the FAA in October 1984 and its Cargomaster freighter variant was developed for FedEx. The longer 208B Super Cargomaster first flew in 1986 and was developed into the passenger 208B Grand Caravan. The strutted, high wing 208 typically seats nine passengers in its unpressurized cabin, is powered by a single Pratt & Whitney Canada PT6A tractor turboprop and has a fixed tricycle landing gear, floats, or skis. As of November 2017, 2,600 had been delivered and 20 million flight hours logged. Caravans have been used for flight training, commuter airlines, VIP transport, air cargo, and humanitarian missions. Development On November 20, 1981, the project was given a go-ahead by Cessna for its Pawnee engineering facility. John Berwick, chief engineer at Pawnee, conc ...

Short Mayo Composite
The Short Mayo Composite was a piggy-back long-range seaplane/flying boat combination produced by Short Brothers to provide a reliable long-range air transport service to North America and, potentially, to other distant places in the British Empire and the Commonwealth. Development Short Brothers had built the Empire flying boats which were capable of operating long range routes across the British Empire but could only attempt the trans-Atlantic route by replacing passenger and mail-carrying space with extra fuel. It was known that aircraft could maintain flight with a greater payload than that possible during takeoff. Major Robert H. Mayo, the Technical General Manager at Imperial Airways, proposed mounting a small, long-range seaplane on top of a larger carrier aircraft, using the combined power of both to bring the smaller aircraft to operational height, at which time the two aircraft would separate, the carrier aircraft returning to base while the other flew on to its ...

Volumetric Weight
Dimensional weight, also known as volumetric weight, is a pricing technique for commercial freight transport (including courier and postal services), which uses an estimated weight that is calculated from the length, width and height of a package. The shipping fee is based upon the dimensional weight or the actual weight, whichever is greater. Significance Shipping costs have historically been calculated on the basis of gross weight in kilograms or pounds. By charging only by weight, lightweight, low density packages become unprofitable for freight carriers due to the amount of space they take up in the truck/aircraft/ship in proportion to their actual weight. The concept of dimensional weight has been adopted by the transportation industry worldwide as a uniform means of establishing a minimum charge for the cubic space a package occupies. In fact, UPS and FedEx both announced that starting 2015, shipping charges on all shipments (air and ground) will be determined by ...

Airmail
Airmail (or air mail) is a mail transport service branded and sold on the basis of at least one leg of its journey being by air. Airmail items typically arrive more quickly than surface mail, and usually cost more to send. Airmail may be the only option for sending mail to some destinations, such as overseas, if the mail cannot wait the time it would take to arrive by ship, sometimes weeks. The Universal Postal Union adopted comprehensive rules for airmail at its 1929 Postal Union Congress in London. Since the official language of the Universal Postal Union is French, airmail items worldwide are often marked ''Par avion'', literally: "by airplane". For about the first half century of its existence, transportation of mail via aircraft was usually categorized and sold as a separate service (airmail) from surface mail. Today it is often the case that mail service is categorized and sold according to transit time alone, with mode of transport (land, sea, air) being decided on ...

Cargo Airline
Cargo airlines (or air freight carriers, and derivatives of these names) are airlines mainly dedicated to the transport of air cargo, cargo by air. Some cargo airlines are divisions or subsidiaries of larger passenger airlines. In 2018, airline cargo traffic represented 262,333 million tonne-kilometres with a 49.3% Load factor (transportation), load factor: % for dedicated cargo operations, and % within mixed operations (belly freight of passenger airliners). Freight rates Amid the COVID-19 pandemic, adjusted cargo capacity fell by 4.4% in February while air cargo demand also fell by 9.1%, but the Impact of the COVID-19 pandemic on aviation, near-halt in passenger traffic cut capacity even deeper as half of global air cargo is carried in passenger jets’ bellies. Air freight rates rose as a consequence, from $0.80 per kg for transatlantic cargoes to $2.50-4 per kg, enticing passenger airlines to operate cargo-only flights through the use of preighters, while cargo airlines brin ...

Piper PA-31 Navajo
The Piper PA-31 Navajo is a family of cabin-class, twin-engined aircraft designed and built by Piper Aircraft for the general aviation market, most using Lycoming engines. It was also license-built in a number of Latin American countries. Targeted at small-scale cargo and feeder liner operations and the corporate market, the aircraft was a success. It continues to prove a popular choice, but due to greatly decreased demand across the general aviation sector in the 1980s, production of the PA-31 ceased in 1984. Design and development At the request of company founder William T. Piper, Piper began development of a six- to eight-seat twin-engined corporate and commuter transport aircraft in 1962 under the project name ''Inca''. The type, now designated the PA-31 and looking like a scaled-up Twin Comanche, was officially announced in late 1964 after its first flight on 30 September that year. It was a low-wing monoplane with a conventional tail, powered by two Lycoming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 purpose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airline
An airline is a company that provides air transport services for traveling passengers and freight. Airlines use aircraft to supply these services and may form partnerships or 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 operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or charter operators. The 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 1980s and back to large-scale privatization following the mid-1980s. Since the 1980s, there has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
