The development of the LJ45 was announced by Bombardier in September, 1992, and first flight of the prototype aircraft took place in 1995, with the first customer aircraft subsequently delivered in January, 1998. The cockpit is equipped with a four-screen Honeywell Primus 1000 EFIS avionics system. The aircraft is powered by two Honeywell TFE731-20 engines, a version developed specifically for this airframe. An internal APU provides ground power.
The Learjet 45XR is an upgraded version introduced in June, 2004, offering higher takeoff weights, faster cruise speeds and faster time-to-climb rates as compared to the LJ45. The increases are due to the upgrading of the engines to the TFE731-20BR configuration. LJ45 owners can upgrade their aircraft through the incorporation of several service bulletins.
