The '''Vickers Viscount''' is a retired 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 [[Cabin pressurization|pressurisation]], reductions in vibration and noise, and panoramic windows. It became one of the most successful and profitable of the first postwar transport aircraft;<ref>[https://books.google.com/books?id=1xpgtVZ9-YEC&pg=PA379 "No Profit in Building Civil Aircraft in Britain?"] ''[[New Scientist]]'', 69(988). 19 February 1976. {{ISSN|0262-4079}}.</ref> 445 Viscounts were built for a range of international customers, including in North America.

===Origins===

The Viscount was a response to the 1943 Brabazon Committee's proposed Type II design for a postwar, small, medium-range, [[Cabin pressurization|pressurised]] aircraft to fly less-travelled routes, carrying 24 passengers up to 1,750&nbsp;mi (2,816&nbsp;km) at 200&nbsp;mph (320&nbsp;km/h).<ref name=greatac>Cacutt 1989, pp. 323–333.</ref> During discussions between the committee and Vickers' chief designer, [[Rex Pierson]], Vickers advocated turboprop power. The committee was not convinced and split the specification into two types, the Type IIA using piston power, which led to the [[Airspeed Ambassador]], and the turboprop-powered Type IIB, which Vickers was selected to develop in April 1945.<ref name="TaylorAE p. 1">Taylor ''Air Enthusiast'' August–November 1984, p. 1.</ref> [[British European Airways]] (BEA) was involved in the design and asked that the aircraft carry 32 passengers, instead, but remained otherwise similar.

The first design in June 1945 was based on the [[Vickers VC.1 Viking|Viking]] with four turboprop engines and 24 seats and designated the VC-2 or Type 453.<ref name="Turner-1">Turner 1968, pp. 1–5.</ref> Later, a double-bubble fuselage was proposed to give extra underfloor cargo space.<ref name="Turner-1" /><ref name = "flight 569"/> Neither was pressurised, but the designers soon realised that for economical operation, an altitude above {{convert|20000|ft|m|abbr=on}} was needed. Thus, pressurisation was required.<ref name="Turner, P.St. John 1968, pg. 2">Turner 1968 p. 2.</ref> The decision for pressurisation resulted in the double-bubble and elliptical fuselage designs being abandoned.<ref name="Turner, P.St. John 1968, pg. 2"/> A circular cross-section variant was offered at the beginning of 1946.<ref name="Turner-1" /> The resulting 28-seat VC-2 was financed by the [[Ministry of Supply]] with an order for two prototypes. Before the contract was signed, though, the government asked for the capacity to be increased to 32. This stretched the fuselage from {{convert|65|ft|5|in|abbr=on}} to {{convert|74|ft|6|in|abbr=on}} and meant an increased wingspan of {{convert|89|ft|m|abbr=on}}.{{#tag:ref|The wings and fuselage of the Viscount were similar to the earlier [[Vickers VC.1 Viking|Viking]]; however no components were shared.<ref name = "flight 569">''Flight'', 20 November 1947, p. 569.</ref>|group=N}}<ref name="Turner-1" />

The contract for the aircraft to [[List of Air Ministry specifications|Air Ministry specification]] C.16/46 was signed on 9 March 1946 and Vickers allocated the designation Type 609 and the name ''Viceroy''.<ref name="Turner-1" /> Although George Edwards had always favoured the 800&nbsp;hp [[Rolls-Royce Dart]]<ref>''Flight'' 20 March 1953, pp. 357–358.</ref> other engines were considered, including the [[Armstrong Siddeley Mamba]], which the government specified for the two prototypes. The choice of the Mamba engine increased the weight, but Vickers made sure the engine nacelle would fit either the Mamba or Dart.<ref name="Turner-1" /><ref name = "flight 568">Flight 20 November 1947, p. 568.</ref> While the Dart progressed better in development, the government asked in August 1947 for the second prototype to be Dart-powered.<ref name="Turner-1" /> The second prototype was designated the 630 and was named as the Viscount.<ref name="Turner-1" /> The first prototype already under construction was converted to the Dart as a 630, as well.<ref name="Turner-1" />

The resulting Vickers Type 630 design was completed at Brooklands by chief designer [[Rex Pierson]] and his staff in 1945, a 32-seat airliner powered by four Dart engines for a cruising speed of 275&nbsp;mph (443&nbsp;km/h). An order for two prototypes was placed in March 1946, and construction started in the company's Foxwarren Experimental Department. Originally named Viceroy after the viceroy of India, [[Lord Louis Mountbatten]], the aircraft was renamed Viscount following India's independence in 1947.<ref>Pigott 2005, p. 125.</ref> Work took place on replacing the Darts with the Mamba, but this was dropped by the time the prototypes were reaching completion. After Pierson's death in 1948, [[George Edwards (aviation)|George Edwards]] (later Sir George Edwards) took over as chief designer and assumed all technical control over the Viscount project.<ref>Gardner 2006, p. 71.</ref>

===Prototypes===

The prototype Type 630, [[Aircraft registration|registered]] ''G-AHRF'', made its maiden flight from the grass airfield at Wisley on 16 July 1948, piloted by [[Joseph Summers|Joseph "Mutt" Summers]], Vickers' chief [[test pilot]].<ref name="Andrews Vickers, pp. 424–5">Andrews and Morgan 1988, pp. 424–425.</ref> The design was considered too small and slow at 275&nbsp;mph (443&nbsp;km/h), making the per-passenger operating costs too high for regular service, and BEA had placed an order for 20 piston-engined Airspeed Ambassadors in 1947. Retrospectively commenting on Britain's aviation industry, Duncan Burn stated: "Had BEA committed itself to full support of the Viscount... it was quite likely that the smaller version would have gone into production... It was in a sense BEA's lack of enthusiasm for the [Type] 630 which made possible the [Viscount's] success."<ref>Burn 1958, pp. 72–73.</ref>

Early flight trials, however, showed the qualities of a turboprop, resulting in a February 1949 order from the Ministry of Supply for a prototype of a stretched version with more powerful engines, the Type 700.<ref name="Story p. 86">''Flight'', 15 July 1955, p. 86.</ref> Meanwhile, the first prototype Type 630 was awarded a restricted [[Certificate of Airworthiness]] on 15 September 1949,<ref name="Jackson v3, p. 224">Jackson 1988, p. 224.</ref> followed by a full certificate on 27 July 1950, which allowed the aircraft to be placed into trial service with BEA on 29 July to familiarise the pilots and ground crew with the new aircraft. It flew scheduled flights between London and Paris, and London and [[Edinburgh]] until 23 August 1950.<ref name="Andrews Vickers, p. 427">Andrews and Morgan 1988, p. 427.</ref> The 29 July 1950 flight between [[RAF Northolt|Northolt]] and [[Paris – Le Bourget Airport]] with 14 paying passengers was the first scheduled airline flight by any turbine-powered aircraft.<ref name="Turner9">Turner 1968, p. 9.</ref>

[[File:Vickers 663 Tay Viscount.jpg|thumb|Type 663 Tay Viscount demonstrating at Farnborough in September 1950]]
The second prototype Viscount, the '''Type 663''' testbed, had two [[Rolls-Royce RB.44 Tay|Rolls-Royce Tay turbojet]] engines, and first flew in RAF markings as [[United Kingdom military aircraft serials|serial]] ''VX217'' at Wisley on 15 March 1950.<ref name="Andrews Vickers, pp. 425–6">Andrews and Morgan 1988, pp. 425–426.</ref> It was demonstrated at the [[Farnborough Airshow|Farnborough SBAC Show]] in September and was later used in the development of powered controls for the [[Vickers Valiant|Valiant]] bomber.<ref name="Jackson v3, p. 224"/> It later was used as a test bed by [[Boulton Paul]] Ltd for the development of [[Fly-by-wire|electronic flight-control]] systems.<ref>[http://www.flightglobal.com/pdfarchive/view/1962/1962%20-%200461.html "Flight Systems: Electrical Flight Controls".] ''Flight International'', Number 2767 Volume 81, 22 March 1962, p. 459.</ref><ref name="flight 42">Flight 11 July 1958, p. 42.</ref>

The designers then went back to the drawing board and the aircraft emerged as the larger '''Type 700''' with up to 48 passengers (53 in some configurations), and a cruising speed of 308&nbsp;mph (496&nbsp;km/h). The new prototype ''G-AMAV'' first flew from Brooklands on 28 August 1950, and served as a development aircraft for the type for several years.<ref name="Story p. 93">''Flight'', 15 July 1955, p. 93.</ref> In late August 1950, BEA placed an order for 20 aircraft; further orders came in the following year from operators such as [[Air France]], [[Aer Lingus]], and [[Misrair]].<ref>Burn 1958, p. 72.</ref><ref name="guttery 52">Guttery 1998, p. 52.</ref> In 1953, the basic cost given for a Viscount was £235,000.<ref>[http://www.flightglobal.com/pdfarchive/view/1953/1953%20-%200385.html "Towards Turboprosperity."] ''Flight'', 20 March 1953. p. 357.</ref>

===Performance and changes===
[[File:Air Zimbabwe Viscount 1981.jpg|thumb|upright|The Viscount's large oval windows, Air Zimbabwe 1981]]

One reporter, after travelling on an Air France Viscount, wrote in 1953: "Noise level was less than that of piston engines. It was a definite relief to be rid of the rough vibrations... The turboprop is an excellent shorthaul airplane and a definite crowd pleaser. The substitution of a lower constant-pitch noise and smoothness for the vibration, grunts, and groans of the piston engine gives the hesitant passenger a feeling of confidence."<ref>''American Aviation'', 7 December 1953, p. 64.</ref> Viscount cabin windows were huge ellipses, 19 by 26 inches.{{#tag:ref|Elliptical windows required the least weight of structural reinforcement in a pressurised fuselage.<ref name = "flight 570">''Flight'', 20 November 1947, p. 570.</ref>|group=N}}<ref>''American Aviation'', 11 April 1955, p. 66.</ref> Viscount operational costs were lower than many rival aircraft;<ref name = "Sutton 434"/> Vickers projected a 700 could carry a 13,000-lb payload from Chicago to New York in 2 hours 45 minutes against a 10-mph headwind, burning 6395&nbsp;lb of fuel.<ref>''American Aviation'', 3 August 1953, p. 43.</ref>

All production Viscounts were powered by the Rolls-Royce Dart turboprop; from its initial 800&nbsp;hp, and then 1,000&nbsp;hp and higher, Rolls-Royce extensively developed the Dart engine, due to its popularity and use on the Viscount and several later aircraft.{{#tag:ref|Other aircraft powered by the Rolls-Royce Dart engine include the [[Fokker F27 Friendship]], [[Hawker Siddeley HS 748]], [[Grumman Gulfstream I]], [[Handley Page Herald]], [[Armstrong Whitworth AW.660 Argosy]], and [[NAMC YS-11]].<ref>Fricker, John.

March 1962. {{ISSN|0015-4806}}. pp. 41, 62, 66.</ref>|group=N}} One key model was the Dart 506 engine, with better fuel efficiency than earlier models, allowing airline Viscounts to fly longer routes, with more payload.<ref>Gunn 1999, pp. 113–114.</ref> With the availability of more powerful engines, Vickers continued to develop the Viscount's design.{{#tag:ref|During the 1960s, the occurrence of [[Fatigue (material)|metal fatigue]] in the Viscount's [[Spar (aviation)|wing spar]] led to Vickers implementing tighter restrictions on the lifespan of the spars.<ref>Hill 2005, p. 123.</ref> To gauge the progress of fatigue and for added safety, electromechanical strain range counters were retrofitted on some aircraft.<ref>Hicks 2001, p. 61.</ref>|group=N}} Later models could carry more passengers and had fewer load limitations.<ref>Gunn 1999, p. 144.</ref>

Three basic versions of the Viscount were built. The first production version was the Type 700 powered by R.Da.3 Dart 505 and later R.Da.3 Dart 506s.<ref name="Turner, P.St. John 1968, pgs. 87-88">Turner 1968, pp. 87–88.</ref>  A subvariant was the type 700Ds powered by R.D.a Dart 510s.<ref name="Turner, P.St. John 1968, p. 88">Turner 1968, p. 88.</ref>

The second version was the Type 800, which was shorter in range and had a higher passenger capacity aircraft than the 700. The fuselage was lengthened {{convert|3|ft|10|in|m|abbr=on}} and the rear pressure bulkhead was moved aft {{convert|5|ft|5|in|m|abbr=on}}, allowing more passengers to be carried. The 800s (excepting the 806s) were powered by the Dart 510.<ref name="Turner, P.St. John 1968, pgs. 42,59-61">Turner 1968, pp. 42, 59–61.</ref>

The third type of Viscount was the 810. It was the same size as the 800s, but was powered with R.Da. 7/1 Mk 225 or Mk 530 Darts. With the greater power, the 810 was faster and longer ranged than the 800.<ref name="Turner, P.St. John 1968, pgs. 62-63">Turner 1968, pp. 62–63.</ref>

Proposed type 740, 850, and 870 Viscounts never left the drawing board.<ref name="Turner, P.St. John 1968, p. 63">Turner 1968, p. 63.</ref>

The Viscount's good performance and popularity with customers encouraged Vickers to privately finance and develop an enlarged and re-engined variant of the Viscount, later designated as the [[Vickers Vanguard]].<ref name="burn 73"/> The Vanguard drew extensively from the knowledge and design of the Viscount, and maintained its advantage of lower operating costs over jet airliners, but its disadvantage in being slower became critical as jets became more available.<ref name="new scientist 50"/>

==Operational history==
Regular passenger flights were launched by BEA on 18 April 1953, the world's first [[Airline timetable|scheduled]] turboprop airline service. BEA became a large user of the Viscount; by mid-1958, BEA's Viscount fleet had carried over 2.75&nbsp;million passengers over 200,000 flight hours.<ref name="flight 44">''Flight'', 11 July 1958, p. 44.</ref> Following BEA's launch of the type, multiple independent charter operators, such as [[British Eagle]], were quick to adopt the Viscount into their fleets.<ref>Manning 2000, pp. 9–10.</ref> During the 1960s, the Viscount formed the backbone of domestic air travel in Scotland.<ref name="warner 39">Warner 2005, p. 39.</ref>

The early operational service of the Viscount quickly proved it to have significant performance advances over its rivals, and orders rapidly rose as a result; up to November 1952, only 42 aircraft had been ordered; by the end of 1953, the order book had risen to 90, and 160 by the end of the following year.{{#tag:ref|Out of the Viscount's total production, 80 percent of aircraft were produced for export customers.<ref name = "Sutton 434">Sutton 2001, p. 434.</ref>|group=N}}<ref name = "burn 73">Burn 1958, p. 73.</ref> Vickers was able to quickly respond to the new orders, as it had gambled on such orders emerging and early on the decision had been taken to commit to a high production rate at the company's own risk.<ref>Burn 1958, p. 84.</ref> In 1957, the Vickers production line was producing the Viscount at a rate of one aircraft every three days.<ref name="new scientist 50">[https://books.google.com/books?id=N-J6bTRyAScC&pg=PA50 "Vicker's £163 million turnover".] ''New Scientist'', 2(27). 23 May 1957. {{ISSN|0262-4079}}. p. 50.</ref>

In October 1953, the Viscount 700 prototype G-AMAV achieved the fastest time (40 hours 41 minutes flying time) in the transport section of the 12,367&nbsp;mi (19,903&nbsp;km) air race from London to [[Christchurch]], New Zealand. The aircraft averaged 320&nbsp;mph (520&nbsp;km/h) in the event, crossing the finish line nine hours ahead of its closest rival, a [[Douglas DC-6]]A of [[KLM]], with the latter winning on handicap. ''En route'', equipped with extra fuel tanks, it flew 3,530&nbsp;mi (5,680&nbsp;km) nonstop from the [[Cocos (Keeling) Islands]] to Melbourne's [[Essendon Airport]] in 10 hours 16 minutes (343.8&nbsp;mph).<ref name="Story p. 93"/><ref name="Race">''Flight'', 16 October 1953, pp. 521–523.</ref><ref>Gunn 1999, pp. 100–101.</ref>

[[Trans Australia Airlines]] (TAA) received its first Viscount in 1954, and the aircraft quickly proved profitable, leading to additional orders.<ref>Gunn 1999, pp. 134, 145.</ref> The Viscount proved to be an invaluable aircraft for TAA, aviation author John Gunn stating, "TAA had achieved dominance on Australia's trunk routes with its turboprop Viscounts".<ref name = "Gunn 134">Gunn 1999, p. 134.</ref> TAA procured over a dozen Viscounts, and purchased later turboprop aircraft such as the [[Fokker F27 Friendship]];{{#tag:ref|The Fokker Friendship was powered by the same Rolls-Royce Dart engine as the Viscount.

The policy took practical effect when Ansett purchased the failing Australian National Airways in 1957, resulting in it being the only competitor for the government-owned TAA. Unstated was the requirement for both airlines to have identical equipment.

[[File:Trans-Canada Airlines Vickers Viscount (1).jpg|thumb|Trans-Canada Airlines Viscount making a low pass sometime in the 1960s]]
The first North American airline to use turboprop aircraft was [[Trans-Canada Air Lines]] (TCA), with a small fleet of Type 700 Viscounts. Initially, TCA was cautious of the Viscount due to the turboprop engine being a new technology, and a preference had existed for acquiring the piston-engined [[Convair CV-240 family|Convair CV-240]], instead; praise of the Viscount from pilots and a promise from Vickers to make any design changes desired by TCA persuaded it to procure the Viscount, instead.{{#tag:ref|In meeting the requirements of United States market, Vickers developed an "Americanised" version of the Viscount; this later acted as the basis for most of the export models sold.<ref name = "flight 44" /> Many localised avionics systems were often fitted, such as American-sourced radios on Viscounts bound for service with US operators.<ref>Hill 2005, p. 41.</ref>|group=N}} On 6 December 1954, the first Viscount was delivered to Canada in a large media event that included an improvised aerial display.<ref>Pigott 2005, p. 127.</ref>

TCA became a prolific operator of the type, placing multiple follow-up orders for additional Viscounts. By 1958, TCA had an operational fleet of 51 Viscounts.<ref name="flight 48">''Flight'', 11 July 1958, p. 48.</ref> Aviation author Peter Pigott later wrote: "For TCA and Vickers, the Viscount was a public-relations coup. Passengers loved the quiet ride and panoramic windows. No other airline in North America flew turbo-prop airliners then, and no other British aircraft was bought by American airlines in such quantity."<ref>Pigott 2005, pp. 127–128.</ref> TCA operated the Viscount for two decades until [[Air Canada]] (TCA relabelled with a name equally at home in English and French), ended Viscount services in 1974. The type was replaced by the [[McDonnell Douglas DC-9]].<ref name = "Pigott 128" />''[[Routine Flight]]'' (1955) featured the TCA introduction of the Viscount in this [[National Film Board of Canada]] documentary.

TCA's procurement of the Viscount generated considerable interest from airlines and industry figures across the United States, including American aviation pioneer [[Howard Hughes]], who purchased 15 Viscounts immediately after personally flying one.<ref name="Pigott 128">Pigott 2005, p. 128.</ref><ref>"Hughes Buys 15 Vickers Planes for $12 Million, Plans to Make Caravelles."

The first airline in Latin America to operate the Viscount was [[Cubana de Aviación]]. Cubana's −755D Viscounts, delivered in 1956, were placed on the [[Havana]]-Miami and [[Varadero]]-Miami routes, and were successful at raising Cubana's market share on these routes.<ref>Hill 2005, p. 51.</ref> During the 1958 Cuban elections, a Cubana Viscount was hijacked by gunmen aligned with the [[26th of July Movement]]; the aircraft crash-landed in the sea, reportedly killing 17 of the 20 occupants.<ref>Márquez-Sterling 2009, pp. 169–173.</ref> When the US government imposed its [[United States embargo against Cuba|embargo]] on Cuba in 1962, Cubana decided to sell all of its Viscounts. They were replaced by Soviet-built turboprop aircraft.{{citation needed|date=September 2012}}

[[South African Airways]] (SAA) was another major operator of the Viscount; by January 1959, it was operating on all of SAA's domestic routes.<ref>Guttery 1998, pp. 187–88.</ref> In 1961, SAA had seven Viscounts, and acquired a further aircraft from Cuba in the following year.{{#tag:ref|South Africa Airways had intended to procure more than one Viscount from Cuba; arrangements proposed included an exchange for a pair of [[Lockheed Constellation]]s, but this did not happen.<ref name = "guttery 188" />|group=N}}<ref name="guttery 188">Guttery 1998, p. 188.</ref> In 1965, SAA began receiving [[Boeing 727]]s, which had been selected the previous year as a jet-powered replacement for the Viscount.<ref name="guttery 188"/> SAA sold its last Viscount to [[British Midland]] in the 1970s.<ref>Guttery 1998, p. 190.</ref>
