The Falcon 900EX is alo equipped with a Honeywell Primus avionics suite. 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. The Falcon 900EX was certificated in 1996 and was in production until 2004, when it was superseded by the Falcon 900EX EASy.
The Falcon 2000EX shares the Falcon 900's wing and forward fuselage. It is a twin-engine transcontinental business jet with a cabin seven feet shorter than the Falcon 900. The Falcon 2000EX was announced in 2000. The Falcon 2000EX has more fuel capacity than the Falcon 2000, Pratt and Whitney 308C power plants, and 700 nautical miles longer range. It received certification in 2003 and was in production until 2005, when it was replaced by the Falcon 2000EX EASy.
