Bombardier CRJ family The Bombardier Canadair Regional Jet (CRJ) is family of regional airliner manufactured by Bombardier, and based on the Canadair Challenger business jet. Design studies began in 1987, with the first prototype flying on May 10, 1991. The flight deck includes the all glass cockpit Collins "Pro-Line 4" avionics suite that is EFIS based and features six CRT displays. The wide fuselage of the Challenger suggested early on to Canadair officials that it would be straightforward to stretch the aircraft to provide more seats, and there was a plan for a Challenger 610E, which would have had seating for 24 passengers. It didn't happen, the effort being canceled in 1981, but the idea didn't go away, either. In 1987, studies began for a much more ambitious stretched configuration, leading to the formal launch of the Canadair Regional Jet program in the spring of 1989. The "Canadair" name was retained despite the fact that Bombardier had bought out the company. The first of three development machines for the initial CRJ-100 performed its first flight on 10 May 1991, though one of the prototypes was lost in a spin mishap in July 1993, The type obtained certification in late 1992, with initial delivery to customers late in that year. Variants Several models of the CRJ have been produced, ranging in capacity from 40 to 86 passengers. CRJ-200 The CRJ-200 is identical to the CRJ-100 except for its engines, which were upgraded to the -3B1 model, offering improved efficiency. Like the -100, the -200 has 50 passenger seats, two pilot seats, one flight attendant jumpseat, and one pilot observer seat. The normal airline configuration is 2+2 seating in rows 1 through 12 and 2+0 in row 13, with the lavatory taking up the right side of row 13. There is also an option to add a second flight attendant jumpseat at the rear of the cabin. CRJ-700 Stretched 70-seat version. The CRJ-700 is equipped with the General Electric CF34-8C1 engine. Maximum speed is Mach .85 at a maximum altitude of 41,000 feet (12,500 m). The CRJ-700 features a new wing with leading edge slats and a stretched and slightly widened fuselage. This enables the aircraft to carry up to 78 passengers with a crew of 2 plus cabin crew. The CRJ-700 comes in two subvariants - Series 701 and Series 705. The Series 705 is actually a CRJ-900, with a business class and a reduced maximum seating capacity to allow operation with scoped regional airlines. Some regional airlines have contracts with their major airlines that limit the maximum passenger capacity of aircraft they operate. CRJ-900 Stretched 86-seat version, with the GE CF-348C5 engines (13,360 lb thrust with APR) and added leading edge slats. Max GTOW is 82,500 pounds.The airplane is loosely based on the CRJ-200 series with a few major improvements. The environmental packs have a target temperature instead of a hot-cold knob. The cabin has a recirc fan which aids in cooling and heating. The engines are controlled by FADEC digital engine control instead of control cables and a fuel control unit. The cabin floor has been lowered 2 inches which gains outward visibility from the windows in the cabin. In typical service the CRJ-900 can cruise 8-10,000 ft higher with a slightly higher fuel burn and an average true airspeed of 450-500 knots, a significant improvement over its predecessor.
