The Learjet 45XR is an upgraded version of the Model 45, introduced in June, 2004, offering substantially higher takeoff weights, faster cruise speeds and faster time-to-climb rates than the Model 45, chiefly through modifications to the engine.
The XR allowed a gross weight 1,000 pounds greater than the original Model 45, greatly increasing payload and fuel/range options. The aircraft also has exceptionally short runway requirements for mid-size bizjets, capable of loaded flights from 4,000-foot runways.
The 45XR’s performance and specifications increases are due to the upgrading of the engines to the TFE731-20BR configuration, flat-rated to 3,500 pounds thrust, even at 104 degrees Fahrenheit, well above the 88-degree mark for that power from the original Model 45’s TFE731-20 engines.
The Model 45 cockpit is equipped with a four-screen Honeywell Primus 1000 EFIS avionics system, with TCAS and EGPWS.
