The Bombardier CRJ700, CRJ900, and CRJ1000 are regional airliners based on the Bombardier CRJ200. Final assembly of the aircraft is at Montréal-Mirabel International Airport in Mirabel, Québec, near Montreal. DevelopmentFollowing the success of the CRJ100/200 series, Bombardier produced larger variants in order to compete with small airliners such as the Boeing 717, the Boeing 737-600, the Embraer E-Jets and the Airbus A320 family. CRJ700
The CRJ700 is a stretched 70-seat derivative of the CRJ200, equipped with the General Electric CF34-8C1 engine. Maximum speed is Mach 0.85 at a maximum altitude of 41,000 feet (12,500 m). Depending upon payload, the CRJ700 can travel up to 2250 statute miles (3,600 km) with current engines, and a new variant with CF34-8C5 engines will be able to travel up to 2895 miles (4,660 km). The CRJ700 features a new wing with leading edge slats and a stretched and slightly widened fuselage, with a lowered floor. This enables the aircraft to carry up to 78 passengers with a crew of 2 plus cabin crew. The first flight was in 1999 and it entered service in 2001. It competes with the Embraer 170. The CRJ700 comes in three subvariants - Series 700, Series 701 and Series 702. The 700 is limited to 68 passengers, the 701 to 70 passengers and the 702 to 78 passengers. The aircraft's FAA Type Certificate designation is the CL-600-2C10. The first airline to fly a CRJ700 was Brit Air in 2001. The CRJ700 was replaced in 2008 with the CRJ700NextGen, featuring improved economics and a revised cabin common to the CRJ900NextGen and CRJ1000. In August 2006 260 CRJ700 aircraft (all variants) are in airline service, with 29 further firm orders. Major operators include American Eagle Airlines (25), Air France (Brit Air) (15), Atlantic Southeast Airlines (39), Comair (15), Horizon Air (21), Lufthansa CityLine (20), Mesa Airlines (20), PSA Airlines (14), and SkyWest Airlines (57). Nine other airlines operate the type, but in smaller numbers. CRJ705
The Series 705 is based on the CRJ900, with a business class and a reduced maximum seating capacity to allow operation with regional airlines. Some regional airlines have contracts with their major airlines that limit the maximum passenger capacity of aircraft they operate. Air Canada Jazz was the launch customer for this aircraft in 2005 with 10 executive (business) class and 65 economy seats. The FAA Type Certificate designation of the CRJ705 is the CL-600-2D15. Air Canada Jazz operates 16 Series 705 aircraft. CRJ900
Stretched 90-seat version (in a single class cabin), with the GE CF34-8C5 engines, 13,360 lbf (59,400 N) thrust with APR, and added leading edge slats. Max GTOW is 84,500 pounds. The airplane is loosely based on the CRJ200 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 as the windows become closer to eye level height. The APU is a General Electric unit which supplies much more air to the AC packs and has higher limits for starting and altitude usage. The wingspan is longer, the tail is redesigned with more span and anhedral. In typical service the CRJ900 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. The FAA Type Certificate designation of the CRJ900 is the CL-600-2D24. The first CRJ900 (N901FJ) was a CRJ700 with a longer fuselage plug fore and aft; it rests in Tucson, Arizona, with only flight test and ferry time on it. The CRJ900 competes loosely with the Embraer 175, and according to Bombardier is more efficient per seat-mile. The Embraer airliners have significantly more payload, range and a roomier cabin. In 2007, Bombardier launched the CRJ900NextGen to replace the initial version. The new model has improved economics and a new cabin common to the CRJ700NextGen and CRJ1000. In June 2007 a total of 62 CRJ900 aircraft are in airline service, with 49 further firm orders. Major operators include Mesa Airlines (44) its launch customers, SkyWest Airlines (17) and Mesaba Airlines (18). Comair, flying as Delta Connection, has ordered 14 CRJ900s, with at least 6 in service as of Nov 2007. These are of interest as they are in a two class configuration, with 12 first class seats and 64 coach seats. This is due to a limitation in Delta's contract with its pilots which limits its regional carriers to flying 76-seat aircraft. In July 2008 PLUNA received its fifth plane (from an eventual total of 7). Estonian Air ordered 3 new CRJ900 NG 90-seat aircraft. Also SAS ordered 13 of these in March 2008. Iraqi Airways has ordered six Bombardier CRJ900 NextGen airliners and options on a further four of the type. CRJ1000On 19 February 2007, Bombardier launched the CRJ1000, previously designated CRJ900X, as a stretched CRJ900, with up to 100 seats. The aircraft is scheduled to enter service in late 2009. Bombardier claims that it offers better performance and a higher profit per seat than the competing Embraer E-190. MyAir has ordered 15 CRJ900Xs converted to the CRJ1000. Atlasjet has also indicated interest in the new type. The CRJ1000 successfully completed its first flight in 2008. Bombardier has, however, stated that an introduction into service has been delayed until the first quarter of 2010. On June 14, 2009 Bombardier announced a new firm order for 15 CRJ1000 NextGen aircraft placed by Air Nostrum for a total of 35 CRJ1000 NextGen aircraft. There are 64 firm orders and 4 options for the aircraft. OperatorsNorth America
