Vickers Viscount 812
The Vickers Viscount is a British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner. The Viscount was well received by the public for its cabin conditions, which included pressurisation, reductions in vibration and noise, and panoramic windows. It became one of the most successful and profitable of the first post-war transport aircraft; 445 Viscounts were built for a range of international customers, including in North America. Development Origins The Viscount was a response to the 1943 Brabazon Committee's proposed Type II design for a post-war small medium-range pressurised aircraft to fly less-travelled routes, carrying 24 passengers up to 1,750 mi (2,816 km) at 200 mph (320 km/h).Cacutt 1989, pp. 323–333. During discussions between the committee and Vickers' chief designer, Rex Pierson, Vickers advoc ...

Airspeed Ambassador
The Airspeed AS.57 Ambassador is a British twin piston-engined airliner that was designed and produced by the British aircraft manufacturer Airspeed Ltd. It was one of the first postwar airliners to be produced. The Ambassador was developed in response to a requirement identified by the Brabazon Committee for a twin-engined short-to-medium-haul airliner as a replacement for the ubiquitous Douglas DC-3. Airspeed assembled a design team in 1943, which initially worked on a smaller proposal powered by Bristol Hercules radial engines; this was quickly superseded by a larger–capacity design aimed at better fulfilling the expansion in postwar civil air travel, although several entities doubted Airspeed's projected growth in air travel. While outfitted with the new but conventional Bristol Centaurus radial engines, the Ambassador was designed to accommodate four Napier Nomad turbo-compound engines, a then-recent innovation. Its fuselage was compatible with pressurisation, this bei ...

Certificate Of Airworthiness
A standard certificate of airworthiness is a permit for commercial passenger or cargo operation, issued for an aircraft by the civil aviation authority in the state/nation in which the aircraft is registered. For other aircraft such as crop-sprayers, a Special Airworthiness Certificate (not for commercial passenger or cargo operations) must be issued. Legal authority A certificate of airworthiness (CoA), or an airworthiness certificate, is issued for an aircraft by the civil aviation authority in the state in which the aircraft is registered. The CoA attests that the aircraft is airworthy insofar as the aircraft conforms to its type design. Each certificate is issued in one of a number of different categories when the aircraft is registered in the name of the owner. Thereafter, a yearly currency fee is payable to renew the CoA. If this fee is not paid when due, the certificate expires and the owner must apply again for the certificate. The CoA can only be issued when a maintenanc ...

Test Pilot
A test pilot is an aircraft pilot with additional training to fly and evaluate experimental, newly produced and modified aircraft with specific maneuvers, known as flight test techniques.Stinton, Darrol. ''Flying Qualities and Flight Testing of the Airplane.'' American Institute of Aeronautics and Astronautics, Inc., 1996, p. 265 History Test flying as a systematic activity started during the First World War, at the Royal Aircraft Establishment (RAE) in the United Kingdom. An "Experimental Flight" was formed at the Central Flying School. During the 1920s, test flying was further developed by the RAE in the UK, and by the National Advisory Committee for Aeronautics (NACA) in the United States. In the 1950s, NACA was transformed into the National Aeronautics and Space Administration, or NASA. During these years, as work was done into aircraft stability and handling qualities, test flying evolved towards a more qualitative scientific profession. In the 1950s, test pilots were ...

Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by Chicago Convention, international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a ...

Joseph Summers
Captain Joseph "Mutt" Summers, (10 March 1904 – 16 March 1954) was chief test pilot at Vickers-Armstrongs and Supermarine. During his career, Summers flew many first flights on prototype aircraft, (a record of 54 by a test pilot), from the Supermarine Spitfire, to the Vickers Valiant. He also holds the current second place record for 366 general types tested, below Eric "Winkle" Brown, Eric "Winkle" Brown's 487. Career Captain Joseph "Mutt" Summers received his nickname "Mutt" during his early days in the RAF from his habit of urinating before takeoff on the small rear wheel or skid of the aircraft he was testing. This led to his being accused of christening his aircraft like a dog marking its territory. He did this because he was aware that during some crashes a full bladder could prove fatal. Paul Brickhill (in ''The Dam Busters'') referred to the two test pilots Joseph Summers and Jeffrey Quill, as "Mutt" and "Jeff", alluding to the characters in the pioneering American com ...

Armstrong Siddeley Mamba
The Armstrong Siddeley Mamba was a British turboprop engine produced by Armstrong Siddeley in the late 1940s and 1950s, producing around 1,500 effective horsepower (1,100 kW). Armstrong Siddeley gas turbine engines were named after snakes. Design and development The Mamba was a compact engine with a 10-stage axial compressor, six combustion chambers and a two-stage power turbine. The epicyclic reduction gearbox was incorporated in the propeller spinner. Engine starting was by cartridge. The Ministry of Supply designation was ASMa (Armstrong Siddeley Mamba). The ASMa.3 gave 1,475 ehp and the ASMa.6 was rated at 1,770 ehp. A 500-hour test was undertaken in 1948 and the Mamba was the first turboprop engine to power the Douglas DC-3, when in 1949, a Dakota testbed was converted to take two Mambas. The Mamba was also developed into the form of the Double Mamba, which was used to power the Fairey Gannet anti-submarine aircraft for the Royal Navy. This was essentially two M ...

Rolls-Royce Dart
The Rolls-Royce RB.53 Dart is a turboprop engine designed and manufactured by Rolls-Royce Limited. First run in 1946, it powered the Vickers Viscount on its maiden flight in 1948. A flight on July 29 of that year, which carried 14 paying passengers between Northolt and Paris–Le Bourget Airport in a Dart-powered Viscount, was the first regularly scheduled airline flight by a turbine-powered aircraft.Turner 1968, p. 9. The Viscount was the first turboprop-powered aircraft to enter airline service - British European Airways (BEA) in 1953. The Dart was still in production forty years later when the last Fokker F27 Friendships and Hawker Siddeley HS 748s were produced in 1987. Following the company's convention for naming gas turbine engines after rivers, this turboprop engine design was named after the River Dart. History Designed in 1946 by a team led by Lionel Haworth, the Dart had a two-stage centrifugal compressor design derived from the earlier Rolls-Royce Clyde. The Dart ...
