Bombardier Challenger 604

Bombardier began deliveries of the Challenger 604 in 1996. The 604 is a longer-range derivative of the 601-3R with a larger fuel capacity, airframe structural improvements,  and upgraded CF34-3B engines. Standard avionics include a Collins Pro Line 4 package, dual Collins FMS-6000 FMS, dual Litton LTN-101 IRS and Collins WXP-4220 digital turbulence detection radar.

Due to its flexible deployability, it is not only ideally suited for short to medium-range flights but also for transatlantic flights. With a speed of  460 knots, the Challenger 604 compares favorably to even the most modern airliners. There were 365 of these models manufactured. The Challenger 604 was later replaced by the Challenger 605 in 2007.
