The Challenger 850 ELR 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 ELR 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 ELR’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 ELR 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 ELR 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 ELR 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.
One item that remains intact from the large, airliner predecessor is the ELR’s roomy cabin. With the same interior dimensions, the high-capacity jet offers plenty of room for up to 16 passengers but 12 is standard. The interior measures 48.4 feet long, 8.2 feet wide and 6.1 feet high (stand-up, of course). The ELR is usually divided in three compartments and seats three across. There is a generous aft and a galley complete with a microwave, convection oven and refrigerator. The Challenger 850 ELR is fully capable of accommodating a large group, compared to most executive aircraft, and in true comfort.
The Challenger 850 is unique in that it originated from an airliner. It is an ideal executive jet for larger capacity travel, maintaining the spatial components of the airliner. However, the real appeal is that the 850 performs similar to a smaller, faster business jet, even with its superior accommodations. A redesign allows the aircraft to complete long-range travel efficiently. It is the perfect investment for a big company.
