The Scottish Aviation Pioneer was an STOL aircraft manufactured by Scottish Aviation in Scotland. It was used for casualty evacuation and communications and could accommodate a pilot and up to four passengers.
The Pioneer was planned to meet the requirements of Air Ministry Specification A.4/45 for a light communication aircraft. The three-seat prototype A.4/45, powered by a 240 hp de Havilland Gipsy Queen was a three-seat high-wing cabin monoplane. Four prototypes were ordered, under the name "Scottish Aviation Prestwick Pioneer" (Serials VL515, VL516, VL517, and VL518). In the event, only the first two were completed. The prototype aircraft (VL515) first flew in 1947. [1]
The use of the Gipsy Queen engine resulted in disappointing performance, and so the A.4/45 was not ordered by the RAF. Scottish Aviation decided instead to produce a civil version. This was achieved by fitting the two prototypes (VL515 and VL516) with new, more powerful engines as the "Pioneer II".
The prototype Pioneer II was the former prototype Pioneer I, (VL515) which was civil registered as G-AKBF. Powered by a 520 hp Alvis Leonides engine, and first flew on 5 May 1950. The second prototype Pioneer I (VL516) was similarly converted, and civil registered as G-ANAZ.. [2] The Pioneer II demonstrated excellent STOL performance, and was ordered by the RAF as the Pioneer CC.1.
Production examples of the Pioneer CC.1 were fitted with full-span controlled leading-edge wing slats and large-area Fowler-type trailing edge flaps, giving a take-off run of 225 feet and a landing run of only 200 feet.
The first Pioneer CC.1 to be delivered to the RAF, on 11 August 1953, was serialled XE512. Ironically, XE512 was essentially the prototype Prestwick Pioneer I from 1947, re-engined with the Alvis Leonides engine, and refurbished for RAF use. (Thus, VL515 became G-AKBF, and then returned to a military serial as XE512). The next three aircraft delivered (constructors numbers 102, 103 and 104) were likewise the second prototype VL516/G-ANAZ plus the partly completed third and fourth prototypes VL517 and VL518. As XE513, XE514 and XE515 they were delivered on 15 August 1953, 3 September 1953 and 10 February 1954 respectively. Two of these first batch of four are illustrated on this page.
The RAF used the Pioneer extensively for tasks such as casualty evacuation in the Malayan Emergency, Aden and Cyprus. With its unusually large slats and flaps, it was able to operate out of very short, unprepared strips and could take off in as little as 225 ft. The Pioneer remained operational in small numbers until 1969. [3] Pioneers were also used by the Royal Ceylon Air Force and the Royal Malayan Air Force. [1]
One of the surviving Pioneers CC.1 has serial number XL703 which was delivered to the RAF on 18 December 1956, and has been preserved by the RAF Museum since October 1968. It has been displayed by the RAF Museum at Cosford since April 1989; since 2014 it has been displayed with fake marks as XL554. [4] There is also another on display in Sri Lanka in the Sri Lanka Air Force Museum at Ratmalana, and a further example at the RMAF Museum, Kuala Lumpur.

The Westland Whirlwind helicopter was a British licence-built version of the U.S. Sikorsky S-55/H-19 Chickasaw. It primarily served with the Royal Navy's Fleet Air Arm in anti-submarine and search and rescue roles.
The de Havilland Canada DHC-1 Chipmunk is a tandem, two-seat, single-engined primary trainer aircraft designed and developed by Canadian aircraft manufacturer de Havilland Canada. It was developed shortly after the Second World War and sold in large numbers during the immediate post-war years, being typically employed as a replacement for the de Havilland Tiger Moth biplane.
The de Havilland DH.82 Tiger Moth is a 1930s British biplane designed by Geoffrey de Havilland and built by the de Havilland Aircraft Company. It was operated by the Royal Air Force (RAF) and other operators as a primary trainer aircraft. In addition to the type's principal use for ab initio training, the Second World War had RAF Tiger Moths operating in other capacities, including maritime surveillance and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers.
The Hawker Fury is a British biplane fighter aircraft used by the Royal Air Force in the 1930s. It was a fast, agile aircraft, and the first interceptor in RAF service capable of speed higher than 200 mph. It was the fighter counterpart to the Hawker Hart light bomber.
The Bristol Type 171 Sycamore was an early helicopter developed and built by the helicopter division of the Bristol Aeroplane Company. The name refers to the seeds of the sycamore tree, Acer pseudoplatanus, which fall with a rotating motion. It has the distinction of being the first British helicopter to receive a certificate of airworthiness, as well as being the first British-designed helicopter to be introduced by and to serve with the Royal Air Force (RAF).
The Scottish Aviation Bulldog is a British two-seat side-by-side training aircraft designed by Beagle Aircraft as the B.125 Bulldog.
The Scottish Aviation Twin Pioneer was a British STOL transport aircraft built by Scottish Aviation Limited at Prestwick Airport, Scotland, during the 1950s. It was designed for both civil and military operators. It was conceived as a twin-engined version of the Pioneer light transport. Both aircraft required "an area only 30m (99ft) by 275m (902ft) in which to operate."
The Hawker Siddeley HS 780 Andover is a twin-engined turboprop military transport aircraft produced by Hawker Siddeley for the Royal Air Force (RAF), developed from the Avro-designed HS 748 airliner. The Andover was named after the Avro Andover, a biplane transport used by the RAF for medical evacuation between the first and second world wars; and RAF Andover, where some of its trials were carried out. The Andover had a kneeling landing gear to make ramp loading easier.
The Westland WS-51 Dragonfly helicopter was built by Westland Aircraft and was an Anglicised licence-built version of the American Sikorsky S-51.
The de Havilland DH.60 Moth is a 1920s British two-seat touring and training aircraft that was developed into a series of aircraft by the de Havilland Aircraft Company.
The Percival Pembroke is a British high-wing twin-engined light transport aircraft built by the Percival Aircraft Company, later Hunting Percival.
The Percival P.56 Provost is a basic trainer aircraft that was designed and manufactured by British aviation company Percival.
The Bristol Type 173 was a British twin-engine, tandem rotor transport helicopter built by the Bristol Aeroplane Company. It was designed by Raoul Hafner as a civil transport helicopter but evoked interest from the military. It did not enter production but was developed into the Bristol Belvedere which was operated by the Royal Air Force from 1961 to 1969.
The Alvis Leonides was a British air-cooled nine-cylinder radial aero engine first developed by Alvis Car and Engineering Company in 1936.
The Fairchild F-11 Husky was a Canadian bush plane designed and manufactured in the post-Second World War era. Despite a promising design, a lack of a suitable powerplant hurt performance, and stiff competition from the de Havilland Beaver and de Havilland Otter designs meant the type never gained a solid foothold in the marketplace.
The Miles M.16 Mentor was a 1930s British single-engined three-seat monoplane training and communications aircraft built by Miles Aircraft Limited.
The Percival Q.6 was a 1930s British communications aircraft built by Percival Aircraft Limited at Luton. Originally, the Percival Q.6 was a civil transport but It was used during the Second World War by the Royal Air Force and Royal Navy as a communications and liaison aircraft. It was a twin-engine, low-wing monoplane with a tailwheel undercarriage.
The Percival Prince is a British light transport of the early postwar period. It was a twin-engine, high-wing, cantilever monoplane of all-metal stressed-skin construction; the undercarriage was of retractable, tricycle type.
