2008 Bombardier Challenger 300
The baseline Challenger 300 was launched at the 1999 Paris Air Show as the Bombardier Continental.[5] An all-new design, it received Transport Canada type approval on 31 May 2003, followed on 4 June by US FAR 25 certification and on 31 July by European JAR 25 approval.[6]Assembled in Wichita, Kansas, it entered commercial service on 8 January 2004 with Flexjet.[7] The new design is not developed from the Challenger 600 or its variants.
Its supercritical wings have a fixed leading-edge and a 27% sweep angle, its 1.15 m (3.8 ft) winglets reduce cruise lift-induced drag by 17%. It climbs to FL410 in 18 min with a 455 kg (1,003 lb) fuel burn at MTOW/ISA, where at a 14,330 kg (31,590 lb) weight it burns 680 kg (1,500 lb)/h at Mach 0.8/445 kn (824 km/h) tas, 875 kg (1,929 lb)/h at Mach 0.83/465 kn (861 km/h) tas.[6] In 2004, the unit cost of the Challenger 300 was US$17.4 million.[6]
The fuselage and the wing are semi-monocoque aluminum structures, the winglets are composite. Outboard ailerons are manually actuated, elevators and rudder are hydraulic with a mechanical backup, fly-by-wire spoilers augment roll control, act as speedbrakes and dump lift on the ground, hydraulic single-slotted fowler flap have four positions: 0/10/20/30°.[8] The Rockwell Collins Pro Line 21 avionics include four LCD displays, an EICAS and Maintenance Diagnostics Computer, an EGPWS, a TCAS II and an ELT.[9]
