W*m iLM Www Bwm JBS mwvLsmjmS^ «U ^ I n w ffA ff ff WLMmMWmS. VLM f ^&Wm W Flight-testing of the CRJ-700 began in May, and deliveries are scheduled to start in early 2001 Challenger business jet, in May 1991, and the pioneering aircraft began airline operations in November 1992. The initial GE CF34-3A-powered CRJ Series 100 has been joined by longer-range ver sions, the lOOERand lOOLR.Thelatestmodel, the Series 200, is equipped with improved CF34-3B1 engines and is also offered in ER and LR versions. Corporate-configured models are also offered, including the Canadair Special Edition (SE) and Corporate Jetliner. Production The final-assembly line is located at the Canadair plant in Montreal, Quebec. Seventy-five CRJ-100/200s were delivered in 1998, and Bombardier is increasing production from 7.5 to 9.5 aircraft a month for 2000. CRJ SERIES 700 THE CRJ SERIES 700, a stretched version of the 50-seat CRJ-100/200, had its maiden flight from Montreal's Dorval Airport on 27 May. Initial deliveries and service entry are scheduled for the first quarter of 2001. Flight testing will involve around l,500h, to be flown with five test aircraft. The CRJ-700 will be certificated in two versions - the basic model and a growth-weight variant. A pair of fuselage plugs increase the aircraft's length by 4.72m. Wing root plugs increase the wing span by 1.83m, and wing area has been increased further by introducing leading edge extensions. The new model also features lead ing edge slats to improve high-lift performance. Changes from the basic CRJ include the introduction of more powerful GE CF34-8C1 engines, in re-designed nacelles. The main landing gear, wheels and brakes have been upgraded for the higher operating weights. The CRJ-700 programme was formally launched in January 1997 with four firm orders from Brit Air of France, plus commitments from other carriers for up to 67 aircraft, includ ing 2 5 from American Eagle. DE HAVILLAND DHC-6 TWIN OTTER THE P&WC 900kW PT6-powered Twin Otterwas first flown in 1965 and the last of more than 830 was built in December 1988. Field Aviation of Canada offers an upgrade, including fitting four-bladed Hartzell pro pellers, which reduce external and internal sound levels. Cabin modifications include fire- retardant composite interior panels and new lightweight seats. Delivered In service 844 623 DE HAVILLAND DASH 7 THE HIGH-WINGED, four-engined, 50- seat Dash 7 was designed for short-field perfor mance, and entered service in 1977. Initial production aircraft were Series 100 passenger or -101 cargo variants. These were superseded by the Series 150 and -151, offering higher operating weight and fuel capacity. Field Aircraft offers a gross-weight increase and cargo door and increased fuel-capacity retrofits. Delivered In service 113 103 Ordered Delivered (CRJ-all variants) 647 317 DASH 8/Q SERIES THE DASH 8/Q Series family encompasses a four model family of twin turboprops spanning the 37- to 70-seat market sector. Since 1998, Bombardier has referred to the Dash 8 family as die Q Series, to signify availability of the NVS active noise and vibration reduction system. The 36-seat Dash 8-100, powered by twin P&WC PW120 turboprops, had its maiden flight in June 1983 and entered service in October 1984. Ahigher-powered ver sion offering increased performance, the -200, was introduced in 1992. The 50/60-seat Dash 8-300, incorporating fuselage plugs forward and aft of the wing to produce a 3.3 5m stretch, was first flown in May 1987, with deliveries beginning in February 1989. The -300 also has a 1.5m greater wingspan, strengthened undercarriage and uprated P&WPW123 engines. The stretched 70-seat Dash 8-400 was launched injune 1995, and had its maiden flight in January 1998. The new model is powered by P&WC/PW150A turboprops driving six-blad- ed composite propellers. Risk-sharing partners in the Q400 pro gramme include Sextant Avionique, which is supplying the integrated avionics suite, and Mitsubishi Heavy Industries, which is responsi ble for the aircraft's forward-, mid- and aft-fuse lage sections, wing-to-body fairing, and vertical and horizontal stabilisers. After l,300h of flight testing, the aircraft received Canadian certification in June. Deliveries to launch customers Uni Air and SAS Commuter are expected to begin during the third quarter. The Ultra Electronics NVS is standard on the Q400, and is available on other Dash 8s and for retrofit for earlier models. It reduces cabin noise to around 77dB. Production Final assembly is undertaken at the de Havilland plant in Downsview, Toronto. Thirty Dash 8s were delivered in 1998, and production continues at about two to three a month. Ordered Delivered 615 522 BRJ-X BOMBARDIER IS studying a new family of regional jets in the 90- to 13 0-seat class, known as the BRJ-X. Two models are originally envis aged - the 95-seat BRJ-X-90 and the stretched, 115-seat BRJ-X-110 - but a larger 13 0-seater is also believed to be on the drawing board. Risk-sharing partners are to be selected by the end of this year and a launch decision is planned for early 2000, leading to a roll-out in the second quarter of 2002 and initial deliveries in late 2003. The design, first unveiled at the Farnborough air show in September 1998, fea tures a five-abreast cabin and a low wing with podded engines. The BRJ-X-115, with an over all length of 36.7m, would be 3.5m longer than the BRJ-X-90. Both models have a wingspan of 28.6m, and require powerplants in the 20- 2 2,0001b-thrust category. They would cruise at M0.8 at a maximum altitude of 37,000ft and offerarange of 3,300km. Bombardier has begun developing a fly-by- wire flight control system for possible incorpo ration in the BRJ-X.
