Royal Air Force andRoyal Navy as a communications andliaison aircraft . It was a twin-engine, low-wingmonoplane with atailwheel undercarriage .Design and development
The Percival Type-Q was Percival's first twin-engine aircraft. It was constructed of wood, with plywood and fabric covering. It had a fixed, tailwheel undercarriage, with faired mainwheels, although four of the production machines would be equipped with retractable undercarriage.
Two versions were designed: the Q.4, a four-seat executive transport, and the Q.6, a six-seat feederliner. The Q.4 was not built. The prototype Q.6, registration "G-AEYE", first flew on
14 September 1937 at Luton. Production started in 1938, and the first production aircraft, registered "G-AFFD", was delivered toSir Philip Sassoon on2 March 1938.Operational history
A small number were exported, including one to the King Ghazi I of Iraq, one to the Lithuanian Ministry of Communications, and two to the Egyptian government in military camouflage. A total of 27 aircraft were built (one prototype and 26 production aircraft).
The
Royal Air Force bought seven aircraft for communications duties underAir Ministry Specification 25/38; these were named Petrel. The Egyptian government bought 2 Q.6s.In the early months of the Second World War, most of the civil Q.6s were requisitioned for service with the RAF and RN. Two Q.6s of the Lithuanian National Airline were impressed by the
Soviet Air Forces in 1940.With one exception, all the civilian Q.6s served with the Royal Air Force during the Second World War. Between 1946 and 1947, four requisitioned Q.6s and three Petrels were sold to civilian buyers.
