The 900EX flies 4,550 nautical miles nonstop, the farthest in its class. And with its classic trijet engine design, the 900EX can use small airports at high altitudes, even on hot days. It's the most versatile aircraft and also one of the safest given its ability to fly slower on approach than its twinjet competitors.
The Falcon 900 is a development of the Falcon 50, itself a development of the earlier Falcon 20. The Falcon 900 design incorporates composite materials.
Improved models include the Falcon 900B, featuring improved engines and increased range, and the Falcon 900EX featuring further improvements in engines and range and an all-glass flight deck. The Falcon 900C is a lower-cost companion to the Falcon 900EX and replaces the Falcon 900B. Later versions are the Falcon 900EX EASy and the Falcon 900DX. At EBACE 2008, Dassault announced another development of the 900 series; the Falcon 900LX incorporating High Mach Blended Winglets designed by Aviation Partners Inc. The same winglets are being developed for the entire Falcon 900 series as a retrofit kit with certification planned for 2011.
