AlliedSignal, the electrical system by Lucas Aerospace, and the air management system by ABG-Semca. In May 2015, production was reduced because of lower demand, caused by slowing economy and geopolitics in Latin America, Russia and China markets. By October 2018, Bombardier had a backlog of 202 aircraft valued at C$14.1 billion ($11 billion), including 128 Global Express aircraft: 67 Global 5000/6000 and four Global 5500/6500. The Global Express program cost $800 million. Design The Global Express is a high speed business/corporate aircraft with a range of at , a maximum altitude and a 14 hours endurance. The semi monocoque airframe is made of lightweight aluminum alloys and composite materials. It has a low wing, tricycle landing gear and fuselage-mounted engines. The clean-sheet design draws upon the earlier Canadair CL-600 and Bombardier CRJ. It shares its fuselage cross-section with these aircraft, paired with a new T-tail and wing. The latter is a supercritical airfoil with a 35° wing sweep and winglets. This flexible wing naturally attenuates turbulence. It was initially powered by two BMW-Rolls-Royce BR710 turbofans controlled by FADEC. The flightdeck features a six screen Honeywell Primus 2000 XP EFIS suite. The Global Express was the business jet with the largest cabin, until being surpassed by the later Gulfstream G650. It can accommodate 12 to 16 passengers in three cabin sections: mostly a forward four-chair club section, a central four-seat conference grouping and an aft three-place divan facing two chairs. Most have a forward galley, crew rest chair and crew lavatory. The 10.3-psi cabin pressurization maintains a 4,500-ft. cabin altitude up to FL 450 and 5,680 ft. at the FL 510 ceiling. The cabin has an unobstructed length of while the floor is dropped by from the Challenger to increase width at shoulder level, while the windows have been repositioned and enlarged by 25%. Operational history It can fly intercontinental ranges without refuelling (e.g. New York City–Tokyo) or between most two points in the world with only one stop. In this class, the Global Express competes with the Airbus Corporate Jet, Boeing Business Jet and Gulfstream G550/650. Most missions are between 3.5 and 4.5 hours in length and cover 1,500-2,000 nmi; flight times can extend to 10 hours at Mach 0.85 (488 knots at ISA) or 12 hours at Mach 0.82-0.83 (476 knots ISA), or a maximum of 13 hours with clear weather at the destination and multiple alternates nearby.
