The Learjet 45XR is a Learjet 45 with a 1,000-pound heavier ramp and takeoff weights as well as two TFE 731-20BR engines. The Learjet 45 was the first completely new model, since the original Learjet 23. It is larger than the Learjet 31 and smaller than the 60. The cabin is seven feet longer than the 31 and has more head and shoulder room than any other aircraft in its class. The cabin has double club seating, a galley and a full aft lavatory. The cockpit has a Honeywell Primus 1000 integrated avionics suite and the Honeywell TFE 731-20BR engines are FADEC equipped. The Learjet 45XR was certificated in 2003 and has been in production since.
