Bombardier Learjet 75

Overview

• There are a number of big improvements that put the 70 and 75 several notches above their predecessors. First of all, engine power will be bumped up from the 40XR/45XR’s 3,500-pounds-thrust per side to 3,850-pounds-thrust, courtesy of new Honeywell FADEC-controlled TFE731-40BR engines. Learjet says the new engines will keep takeoff distance requirements below 4,500 feet, which is a 600-foot reduction compared to the runway-hungry 40XR and 45XR. There’s a nine-percent improvement in hot-and-high performance, the company promises, and yet the engines boast fuel economies that cut fuel burns by four percent. So while the 70 and 75 may have longer maximum ranges (2,040 nm and 2,060 nm, respectively, when flown at Mach 0.75) similar to those of its predecessors (max range of the 40XR in 1,600 nm; for the 45XR, 2,000 nm), they use less fuel getting there. Meanwhile, the 70/75’s maintenance intervals have been set at fixed at 600 flight hours. Together with the performance efficiencies, the company says that fixed-interval maintenance will lower direct operating costs.
