Information: - The PZL M28 Skytruck is a Polish STOL light cargo and passenger plane , produced by PZL Mielec , as a development of license - built Antonov An - 28 . Early licence - built planes were designated PZL An - 28 . The maritime patrol and reconnaissance variants are named PZL M28B Bryza ( '' sea breeze '' ) . - PZL Mielec ("Polskie Zakady Lotnicze" - Polish Aviation Works), formerly WSK-Mielec ("Wytwornia Sprztu Komunikacyjnego") and WSK "PZL-Mielec" is a Polish aerospace manufacturer, based in Mielec. It is the largest aerospace manufacturer in postwar Poland. In 2007 it was acquired by Sikorsky Aircraft Corporation, retaining the brand. - Antonov State Company, formerly the Antonov Aeronautical Scientific-Technical Complex (Antonov ASTC), and earlier the Antonov Design Bureau, is a Ukrainian aircraft manufacturing and services company. Antonov's particular expertise is in the fields of very large aeroplanes and aeroplanes using unprepared runways. Antonov (model prefix An-) has built a total of approximately 22,000 aircraft, and thousands of planes are currently operating in the former Soviet Union and in developing countries. - Takeoff is the phase of flight in which an aerospace vehicle or animal goes from the ground to flying in the air. - An aerospace manufacturer is a company or individual involved in the various aspects of designing, building, testing, selling, and maintaining aircraft, aircraft parts, missiles, rockets, and/or spacecraft. Aerospace is a high technology industry. - The Antonov An-14 Pchelka ("Little Bee", (NATO reporting name Clod) is a Soviet utility aircraft which was first flown on 15 March 1958. It was a twin-engined light STOL utility transport, with two 300hp Ivchenko AI-14RF radial piston engines. Serial production started in 1966, and about 300 examples were built by the time production ended in 1972. The An-14 failed to replace the more successful An-2 biplane, which was manufactured until 1990, (the An-2 is still manufactured on special orders). The An-14's successor, the An-28 with turboprop engines, is still manufactured at PZL Mielec factories in Poland under the names PZL M28 Skytruck and PZL M28B Bryza. - The Antonov An-28 (NATO reporting name Cash) is a twin-engined light prop transport aircraft, developed from the Antonov An-14M. It was the winner of a competition against the Beriev Be-30 for use by Aeroflot as a short-range airliner. It first flew in 1969. A total of 191 were built and 16 remain in airline service as at August 2015. After a short pre-production series built by Antonov, it was licence-built in Poland by PZL-Mielec. In 1993, PZL-Mielec developed its own improved variant, the PZL M28 Skytruck. - An airline is a company that provides air transport services for traveling passengers and freight. Airlines utilize aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body. - An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. - A short takeoff and landing (STOL) aircraft is an aircraft with short runway requirements for takeoff and landing. Many STOL-designed aircraft also feature various arrangements for use on runways with harsh conditions (such as high altitude or ice). STOL aircraft, including those used in scheduled passenger airline operations, have also been operated from STOLport airfields which feature short runways. - NATO reporting names are code names for military equipment of Russia, China, and, historically, the former Eastern Bloc (Soviet Union and other nations of the Warsaw Pact). They provide unambiguous and easily understood English words in a uniform manner in place of the original designations, which either may have been unknown to the Western world at the time or easily confused codes. - A STOLport or STOLPORT was an airport designed with STOL (Short Take-Off and Landing) operations in mind, usually for an aircraft class of its weight and size. The term STOLport did not appear to be in common usage as of 2008. A STOLport normally had a short single runway, in general shorter than . STOLports only accepted certain types of aircraft, often only smaller propeller aircraft, often with limits on the amount of fuel that can be taken. In the United States, short runway facilities are simply known as airports and the term STOLport has not been commonly used since the early 1970s. - Mielec is a city in south-eastern Poland (Lesser Poland), with a population of 60,979 inhabitants, as of June 2009. It is located in the Subcarpathian Voivodeship (Wojewodztwo Podkarpackie) (since 1999); previously it was in Rzeszow Voivodeship (19751998). Mielec is the capital city of Mielec County. - PZL ("Pastwowe Zakady Lotnicze" - State Aviation Works) was the main Polish aerospace manufacturer of the interwar period, based in Warsaw, functioning in 1928-1939. The abbreviation was thereafter - from late 1950s - used as an aircraft brand and as a part of names of several Polish state-owned aerospace manufacturers referring to traditions of the PZL, belonging to the "Zjednoczenie Przemysu Lotniczego i Silnikowego PZL" - PZL Aircraft and Engine Industry Union. After the fall of communism in Poland in 1989, these manufacturers became separate plants, still sharing the PZL name. In the case of PZL Mielec, the abbreviation was later developed as "Polskie Zakady Lotnicze" - Polish Aviation Works. - According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt, concrete, or a mixture of both) or a natural surface (grass, dirt, gravel, ice, or salt). - OJSC AeroflotRussian Airlines, commonly known as Aeroflot (or ) (English translation: "air fleet"), is the flag carrier and largest airline of the Russian Federation. The carrier operates domestic and international passenger and services, mainly from its hub at Sheremetyevo International Airport. - The Beriev Be-30 (NATO reporting name "Cuff") is a Russian regional airliner and utility transport aircraft designed by the Beriev Design Bureau. It was developed specifically for Aeroflot local service routes using short, grass airstrips. It was also designed to be used in the light transport, aerial survey and air ambulance roles. It competed against the Antonov An-28 and the Czechoslovakian LET-410.
