The light 40XR is a slightly smaller version of the Learjet 45 that Bombardier created by cutting about two feet out of the fuselage. It retains the same oval cross section with a cabin width of just more than five feet, providing a roomy space for two-across seats. With a fast cruise speed and excellent performance from small airports, the 40XR is a nimble ride for regional travel. A cruise ceiling of 51,000 feet puts you above the weather and enhances fuel efficiency. Aerodynamic winglets and efficient Honeywell engines also help minimize fuel burn.
