The Learjet 45 and Learjet 45XR are midsize private jets designed and manufactured by Bombardier Aerospace. The Learjet 45XR is an upgraded version of the original Learjet 45, featuring several improvements and enhancements. Both models have since been discontinued, with the Learjet 70/75 succeeding them in Bombardier’s product line.

Aviation International News reports, “Work began on the airplane in 1989 as a replacement to the wildly popular Learjet 35 series. The Model 45 was a clean-sheet-of-paper design that made extensive use of customer focus group data, computer modeling, and lean manufacturing design. The aircraft’s roomy, flat-floor cabin was designed first, and then the rest of the airplane was built around it.”
The Lear 45 and Lear 45XR have a cabin height of 4.92 feet, a width of 5.12 feet, and a length of 19.75 feet. The cabin can accommodate up to eight passengers in a variety of configurations, including a club seating arrangement and a divan. There is a fully enclosed lavatory in the rear of the cabin.
The Learjet 45 has a range of up to 2,120 nautical miles (2,440 miles) and a maximum cruise speed of 535 mph (863 km/h). Two Honeywell TFE731-20 engines power it. The Learjet 45XR has a range of up to 2,158 nautical miles (2,486 miles) and a maximum cruise speed of 535 mph (863 km/h).
The Learjet 45 was priced at around $13 million when it was first introduced, while the Learjet 45XR was priced at around $15.5 million.
The XR version of the Lear 45 was first delivered in 2004 and includes up-rated TFE731-20-BR engines flat-rated at 3,500 pounds of thrust at 104 degrees F, up from the original Lear 45’s rating of 86 degrees F. This power increase reduced balanced field length, especially under high and hot conditions and, of course, improved the aircraft’s climb performance. The XR upgrade also upped the gross weight by a thousand pounds, greatly increasing the type’s utility.
Bombardier's Learjet 45 is a study in contrasts. It is a breakthrough aircraft that had a troubled and lengthy gestation period, and its operators have a strong love-hate relationship with the airplane and its product support.
Business Jet Traveler
New models of private jets come out every year, but it’s only ever so often that a jet is released that is truly innovative. The medium-range Learjet 45, replacing the 35, is one of the rare jets to seamlessly integrate new technology with a tested and successful older design. Its speed and economy are to be expected – being a Learjet – but its remaining features combine to create a high-quality private jet and the 45XR even more so.
