Operational Context
Bombardier Learjet 45 XR — light business jet
The 45 XR first flew in 2004 and entered service in 2004. It incorporated more powerful engines and systems refinements compared with the original 45. The design retained the Learjet’s swept-wing heritage.
Two Honeywell TFE731 turbofan engines producing approximately 3,500 pounds of thrust (15.6 kN) each power the aircraft. Cruise speed approaches 460 knots (852 km/h). Maximum takeoff weight exceeds 21,500 pounds (9,752 kg).
The 45 XR remained competitive in the light jet market until production ended in the 2010s. Its performance and climb capability appealed to corporate and charter operators. Many remain active in business aviation fleets.
