 The Learjet Model 75 variant, first delivered in 2012, is essentially a Model 45XR with more modern engines, engine systems, and Garmin 5000 avionics, and more efficient winglets.The Model 75's Honeywell TFE731-40BR engines yield 10% more takeoff thrust (3,850 pounds) than the -20BR engines powering the Model 45XR, cutting required runway length 12%, allowing a sea-level, standard-day takeoff within 4,440 ft., (versus the Model 45XR's fully equipped need for 5,040 ft).In these conditions, the Model 75 can take off from a 4,500-foot runway, with a full load of passengers and fuel, and fly 1,800 nautical miles (2,070 statute miles).
