Bombardier CRJ700 series

The Bombardier CRJ700, CRJ900, and CRJ1000 are regional airliners manufactured by Bombardier and based on the CRJ200. Final assembly of the aircraft is at Montréal-Mirabel International Airport in Mirabel, Quebec, outside Montreal, Canada.

Development

Following the success of the CRJ100/200 series, Bombardier produced larger variants in order to compete with larger regional aircraft such as Embraer's E-Jets, Fokker's F70/100 series, and the BAe 146/Avro RJ family.

CRJ700 series

Design work on the CRJ700 by Bombardier started in 1995 and the programme was officially launched in January 1997. The CRJ700 is a stretched 70-seat derivative of the CRJ200. Seating ranges from 66 to 78 for the CRJ700 versions, however. The CRJ700 features a new wing with leading edge slats and a stretched and slightly widened fuselage, with a lowered floor.

The early build aircraft were equipped with two General Electric CF34-8C1 engines. However, later build aircraft are now equipped standard with the -8C5 model, which is essentially an uprated 8C1. Most airlines have replaced the older engines with the newer model, while a few have kept the older -8C1 in their fleet. Maximum speed is Mach 0.85 (895 km/hr, 556 mi/hr) at a maximum altitude of 12,500 m (41,000 ft). Depending upon payload, the CRJ700 can travel up to 3,620 km (2,250 mi) with original engines, and a new variant with CF34-8C5 engines will be able to travel up to 4,660 km (2,900 mi).
