LH Cityline CRJ 900 Frankfurt-Bydgoszcz COOL VIEWS! [AirClips full flight ]

The CRJ900 is a stretched 76–90 seat version of the CRJ700. The aircraft features two GE CF34-8C5 engines , 59.4 kN (13 , 400 lbf) thrust with APR , and added leading edge slats. Its maximum ground takeoff weight is 84 , 500 pounds. The airplane is loosely based on the CRJ200with a few major improvements. The environmental packs have a target temperature instead of a hot-cold knob. The cabin has a recirculation 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 Honeywell RE220 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 (C-FRJX) was modified from the prototype CRJ700 by adding longer fuselage plugs fore and aft of the wings; it was later converted into the prototype CRJ1000 by installing longer fuselage plugs. The CRJ900 competes with the Embraer 175 , and is more efficient per seat-mile , according to Bombardier. Mesa Air Group was the launch customer for the CRJ900 painted in America West livery. In 2007 , Bombardier launched the CRJ900 NextGen to replace the initial version. The new model has improved economics and a new cabin common to the CRJ700 NextGen and CRJ1000 NextGen. Mesaba Aviation , operating at the time as Northwest Airlink (now Delta Connection) , was the launch customer , and remains the largest operator of the CRJ900 NextGen. The Mesaba fleet of CRJ900 NextGen aircraft are configured in a
