The Bombardier CRJ700 aircraft is designed to hold 70-78 passengers in a 4-abreast configuration with a lavatory and galley as standard equipment. Bombardier Aerospace offers 3 versions of the CRJ700: the standard CRJ700, the CRJ700 ER and CRJ700 LR. The standard version has a maximum takeoff weight of 72,750 pounds (32,999 kg) and a range of 1,434 nm (1,650 sm / 2,655 km). The Extended Range (ER) variant has a maximum take-off weight of 75,000 pounds (34,019 kg) and range of 1,732 nm (1,993 sm / 3,208 km). The Long Range (LR) model has a maximum take-off weight of 77,000 pounds (34,926 kg) and a range of 2,002 nm (2,304 sm / 3,708 km). The CRJ700 has outstanding performance, capable of max cruise speeds of Mach 0.825 (473 kts / 544 mph / 875 kph), and cruise altitudes up to 41,000 feet.
The Bombardier CRJ700 is powered by two General Electric CF34-8C5B1 turbofan engines that are flat rated to produce 13,790 pounds (61.3 kN) of take-off thrust. These same engines also power the larger CRJ705 and CRJ900, allowing for greater commonality and lower maintenance costs. Originally developed for the United States Air Force, the CF34 family has over 20 million flight hours and is highly regarded as one of the most reliable and efficient powerplants built. In addition to having improved fuel and cooling efficiencies, the Bombardier CRJ700 Series' powerplant delivers a performance envelope comparable to that of a mainline jet.
The CRJ700 is 106 feet, 8 inches (32.5 m) long with a wing span of 76 feet 3 inches (23.2 m). The aircraft requires a radius of only 75 feet (22.86 m) to negotiate a 180-degree turn; a valuable asset at increasingly congested airports. |
