The Falcon 900DX is based on the wide-body design of the Falcon 900EX EASy but with less fuel and a lower purchase price. The Falcon DX is equipped with Dassault’s EASy flight deck. The Falcon 900DX replaces the Falcon 900C and first deliveries were made in late 2005.
The Falcon 900 is a large-size long-range business jet based on the Falcon 50. While similar to the Falcon 50, the Falcon 900 has a new wider and longer fuselage, which can seat three passengers abreast. The biggest thing the Falcon 900 has in common with the Falcon 50 is the supercritical wing. It was incorporated into the aircraft virtually unchanged. Honeywell TFE731-5 engines that produce 4,500 pounds of thrust power the Falcon 900.
The Falcon C is a Falcon B with the Honeywell Primus 2000XP avionics systems found on the Falcon 900EX.
The Falcon EX is a Falcon C with higher rated Honeywell TFE731-60 engines that produce 5,000 pounds of thrust. The Falcon EX also has the upgraded EASy system avionics suite.
