The Challenger 850 derives from Canadair’s Regional Jet series. The regional jet featured greater cabin space and wingspan as well as a sturdier frame. Rebranded in 2003, the airliner became the Bombardier Challenger 850. As a result, the 850 fuses the capabilities of a larger aircraft with the comfort and flexibility of an executive jet.
As a high-capacity business “shuttle,” the 850 requires a large powerhouse. A pair of General Electric CF34-3B1 turbofan engines provide 8,729 lbs of thrust apiece. Inspection interval is “on condition.”
The 850’s all-glass cockpit is equipped with the Collins Pro Line 4 digital avionics package, dual digital comm/nav radios, dual Litton INS and FMS, TCAS, GPWS and WXR-840 color weather radar. The system includes an all-digital highly integrated EFIS, dual FMSs and a two-screen EICAS (with full systems synoptics).
The 850 has undergone many design modifications from the former airliner, making the aircraft more reliable and performance-driven. These include steel brakes in the place of carbon, computer-controlled fly-by-wire system, and single-point and over-fueling. By redesigning its airframe, the 850 can carry an additional 4,000 lbs of fuel than its predecessor, increasing payload, range and takeoff weight.
For a larger aircraft, the Challenger 850 still compares with smaller, faster business jets in regards to performance. The 850 can travel at .85 Mach and reach a certified flight ceiling of 41,000 feet. During climb, it takes a relatively quick 32 minutes to reach 37,000 feet. Its maximum takeoff weight is 53,000 lbs.
