Vickers
Viscount

The world's first turboprop airliner and one of Britain's most successful commercial aircraft.
 
Vickers Viscount 630 G-AHRF ground The prototype Type 630 Vickers Viscount at around the time of its first flight in July 1948.
 
The Viscount had its origins as the Brabazon Committee’s Type IIB. When introduced, it was a complete revolution on BEA’s European and domestic routes, compared with the Douglas DC-3s that it replaced.
 
Initially specified by the Brabazon Committee with only 24 seats, by the time of the prototype Viscount 630 G-AHRF’s first flight, on 16th July 1948, its capacity had been increased to 32 passengers. The fuselage length of the prototype was 74ft 6 in.

A second prototype, designated the Type 663 and carrying serial VX217, was built powered by two Rolls-Royce Tay jet engines. This aircraft served as a test-bed for the Tay and was subsequently operated by Boulton Paul Aircraft, developing powered flight controls systems in support of the development of the Vickers Valiant.

Discussions with British European Airways and the availability of more powerful versions of the Dart engine resulted in the definition of the Type 700 production aircraft. BEA ordered 26 Type 701 with 47 to 53 seats. The increased seat capacity required an 88-inch increase in fuselage length to 81ft 10 in. A single prototype of the Type 700 was built, flying as G-AMAV on 28th August 1950.

The first production Type 701 G-ALWE flew in August 1952, with the type entering full passenger service on 18th April 1953. The type was an immediate success both in terms of economics and passenger appeal and was sold all over the world. It was popular not least for its superb passenger windows and smooth ride.
 
The proven success of the type in BEA service led to orders from Air France, Aer Lingus and Trans-Australian Airlines (TAA). These were followed by key orders for 15 aircraft for Trans-Canada Airlines and 60 aircraft for Capital Airlines. Ultimately, 147 of the 445 Viscounts sold were exported to the North American market.
 
Vickers Viscount 744 N7402 Capital The Viscount achieved notable success in the US market. This is N7402 in the colours of Capital Airlines, which operated 60 of the type.
 
This was followed by the Type 800, which was stretched to by a further 46 inches to 85ft 8in provide a capacity of 57 to 65 seats, dependent upon configuration. The rear bulkhead was also moved aft, resulting in an overall increase in the internal cabin length of no less than 111 inches.
 
Vickers Viscount 802 G-AOJA Take-off of G-AOJA, the first stretched Viscount 802 for BEA.
 
Once again, the lead customer was BEA, whose variant was designated he Type 802. The first Type 802 was G-AOJA, which was first flown at Weybridge on 17th July 1956. The series 800 Viscount can readily be identified by an extra pair of passenger windows on each side, ahead of the plane of the propellers.
 
At its peak, BEA operated a fleet of no less than 77 Viscounts and their popularity and financial success contributed to sales of the type in the export market. Ultimately, more than 60 operators in 40 countries purchased the type.
 
Vickers Viscount 818 Cubana CU-T622 The introduction of the more powerful Viscount 810 led to further sales, including this Viscount 818 CU-T622 of Cubana.
 
The Type 810 introduced a new variant of the Dart engine, the 1,990 ehp Dart 525 engine. This provided improved hot and high take-off performance and allowed an increase in maximum gross weight. Although not produced in the same numbers as the Type 700 series, additional export sales resulted to airlines such as All Nippon Airways, Cubana, Ghana Airways, Pakistan International, Lufthansa and VASP.
 
The success of the type resulted in Vickers-Armstrongs opening a second production line at its Hurn Airport factory, to supplement production at their Weybridge site. The Hurn factory had previously been used for Vickers Varsity production.
 
Overall production comprised three prototypes (one Type 630 G-AMRF, Tay Viscount VX217 and prototype Viscount 700 G-AMAV) and 445 production aircraft.
 
Vickers Viscount 810 G-AOYV with Vanguard fin Viscount 810 demonstrator G-AOYV was used to test ice protection of the Vanguard tail fin.
 
The Vickers Type 810 demonstrator G-AOYV was subsequently adapted with an icing spray rig for fin de-icing tests in support of the development of the Vickers Vanguard.
 
The last Viscount passenger service in Britain was flown in April 1996.
