The Dassault Falcon 20F-5B is an advanced variant of the original Falcon 20 series, which pioneered Dassault’s entry into business aviation. The Falcon 20 program began with the Mystère 20 prototype in 1963, entering production in 1971. The 20F-5B represents a major upgrade over earlier Falcon 20 models, incorporating Honeywell TFE731-5BR engines rated at 4,750 lbs of thrust each, replacing the original CF700 engines. This re-engining program improved fuel efficiency, reduced noise to meet Stage 3 compliance, and extended operational life.
Production of the Falcon 20F-5B occurred during the late 1970s and early 1980s as part of Dassault’s modernization initiative. The aircraft offers a range of approximately 2,000 nautical miles, cruising at Mach 0.78 (455 knots), with a maximum takeoff weight of 30,325 lbs. Balanced field length is about 5,200 ft, and the aircraft operates up to 42,000 ft, making it suitable for regional and transcontinental missions.
The cabin measures 24 ft 5 in long, 6 ft 1 in wide, and 5 ft 8 in high, with a total volume of 587 cu ft. Typical layouts seat 8–9 passengers in a club configuration, complemented by a forward galley and aft lavatory. Internal baggage space totals 60 cu ft, supporting executive travel needs. While not as spacious or long-range as later Falcon models, the 20F-5B remains valued for its reliability, lower operating costs, and compliance with modern noise standards.
Operators appreciate the Falcon 20F-5B for its proven airframe, upgraded engines, and ability to remain competitive in the midsize jet category decades after its introduction.
