Overview 2

The Percival Proctor was a British radio trainer and communications aircraft of the Second World War. The Proctor was a single-engine, low-wing monoplane with seating for three or four, depending on the model.

Design and Development 2

The Percival Proctor was developed from the Percival Vega Gull in response to Air Ministry Specification 20/38 for a radio trainer and communications aircraft. The prototype aircraft first flew on 8 October 1939 and the type was put into production for the Royal Air Force and the Royal Navy. The prototype was tested as an emergency bomber during 1940 but this idea was abandoned as the invasion threat receded. F. Hills & Sons of Trafford Park near Manchester built 812 Proctors of several marks between 1941 and 1945, assembling most of the aircraft at Barton Aerodrome.

Operational History 2

The Proctor was initially employed as a three-seat communications aircraft (Proctor I). This was followed by the Proctor II and Proctor III three-seat radio trainers. In 1941, the Air Ministry issued Specification T.9/41 for a four-seat radio trainer. The Percival P.31, originally known as the Preceptor but was finally redesignated the Proctor IV, was developed for this requirement with an enlarged fuselage. One Proctor IV was fitted with a 250-hp (157 kW) Gipsy Queen engine. This was used as a personal transport by AVM Sir Ralph Sorley but production models retained the 210-hp (157 kW) motor of earlier marks. At the end of World War II, many Proctors of the early marks were sold on to the civil market and were operated in Australia, New Zealand and Europe. The Proctor Mk.IV continued in service with the RAF until the last was withdrawn in 1955.

In 1945, a civil model derived from the Proctor IV was put into production for private owner, business and light charter use as the Proctor V. The RAF purchased four to be used by air attachés. The final model of the line was the solitary Proctor VI floatplane sold to the Hudson’s Bay Company in 1946.
