The wing was designed with a profile optimised for a Mach 0.84 cruise, and was of conventional two-spar light alloy torsion box structure. The fuselage was all-metal semi-monocoque fail-safe design and, by the use of thicker skins than on the Falcon 50, the number of frames was reduced from 43 to 35. Total fuel capacity was 10,735 litres (2,361 Imp gals). Extensive use was made of carbon fibre and aramid composite (Kevlar) materials. Of similar configuration to the Falcon 50 series, the Falcon 900 had increased overall dimensions, a larger fuselage, more powerful engines, and a better performance. Production commenced to meet 45 orders then on hand, and deliveries began in late 1986. The second development aircraft flew for the first time on 30 August 1985. The prototype (F-WIDE), named ‘ Spirit of Lafayette’, was rolled out of the assembly hall on, and made its first flight on 21 September that year. On Dassault-Breguet announced a program to develop an intercontinental three-turbofan executive transport to be known as the Mystere or Falcon 900.
