Learjet 45 XR
In July 2004, Bombardier Learjet brought the Learjet 45 XR aircraft to the market. The Learjet 45 XR was built to improve the performance of the original Learjet 45 and upgrade some of the components of the Learjet 45 aircraft. Currently, Bombardier Learjet only builds the Learjet 45 XR version of the Learjet 45.
Learjet 45 XR Improvements:
The main improvement in the Learjet 45 XR is the engine. In order to bring better performance to the Learjet 45, Learjet used engine enhancements to bring better performance to the Learjet 45 series. The Honeywell TFE731-20BR engine was selected to be the new engine. The TFE731-20BR is almost the same engine as the old TFE731-20AR engine, however some improvements were made on the AR engine to make it better performing and the BR engine was born. The Honeywell TFE731-20BR gave the Learjet 45 XR reduced balanced field lengths at higher temperatures, faster high-speed cruise and improved time-to-climb capabilities, mostly under ISA plus conditions. To learn more about the Learjet 45 engines and how older Learjet 45s can get the upgrade to the BR engine, visit our Learjet 45 Engine page.
Other Learjet 45 XR Improvements:
There were also a few minor improvements to the Learjet 45 interior in the Learjet 45 XR version.
Learjet increased galley storage and improved convenience to systems behind the back lavatory partition. The cabin's lighting system has been updated to a Light Emitting Diode (LED) system, which lasts longer, is more robust, and emits less heat. Also interior components have been redesigned to allow for removal in 20 minutes or less.
