The first business jet developed by the firm, it became the first of a family of business jets to be produced under the same name; of these, both the smaller Falcon 10 and the larger trijet Falcon 50 were direct derivatives of the Falcon 20. Initially known as the Dassault-Breguet Mystère 20, approval to proceed with development of the aircraft was issued during December 1961. It is a low-wing monoplane design, powered by a pair of rear-mounted General Electric CF700 turbofan engines. On 4 May 1963 the prototype made its maiden flight. The first production aircraft was introduced on 3 June 1965. On 10 June 1965, French aviator Jacqueline Auriol achieved the women's world speed record using the first prototype. The Dassault Falcon 20 is a French business jet, often considered to be an easy to fly and relatively visually appealing aircraft. The favourable flight qualities of the aircraft meant that there was no need to incorporate a stick pusher or stall-barrier systems in order to achieve its predictable stall behaviour. The flight controls of the Falcon 20 are hydraulically-powered, augmenting the mechanical pushrods between the cockpit controls and the flight control surfaces. In the event of complete hydraulic failure, the aircraft can be practically flown without any augmentation. The controls incorporate an artificial feel system, optimising the sensations perceivable to the operating pilot to be smooth, predictable, and precise. The Falcon 20 is furnished with a highly swept wing; it is equipped with leading-edge slats to improve its slow speed performance and decrease the stalling speed. When approaching a high angle of attack, the slats are automatically deployed; when nearing a potential stall, the inner section of the slats then retract to provide for a stable and predictable stall with effective aileron controls throughout. Three Falcon 20's served with the RAAF VIP Squadron. For more details of the development, design operational history and 21 variants, click here. Specvifications below are for the Falcon 20F model.
