Learjet 45

Lear 45/45XR Private Jet

The Learjet 45 (LJ45) aircraft is a mid-sized business jet aircraft produced by Bombardier Aerospace.


Bombardier announced the development of the LJ45 in September, 1992, and the maiden flight of the prototype aircraft occurred October 7, 1995, coinciding with the 32nd anniversary of the first flight of the Learjet 23. FAA certification was delayed, and finally attained in September 1997, with the first customer aircraft delivered in January, 1998. The cockpit is equipped with a four-screen Honeywell Primus 1000 EFIS avionics system. The aircraft is powered by two FADEC-controlled Honeywell TFE731-20 engines, a model developed specifically for this airframe. An internal APU provides ground power.

The Learjet 45XR is an upgraded version introduced in June, 2004, offering faster cruise speeds, improved takeoff weights 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.

In size, the LJ45 and LJ45XR fit between the smaller Learjet 31 and Learjet 40 and the larger Learjet 60 in the Lear product line. De Havilland Canada builds the LJ45s wings, and Bombardier subsidiary Short Brothers of Northern Ireland builds the fuselage and empennage.

The Learjet 45 is also one of the main aircraft featured in the Microsoft Flight Simulator including Flight Sim 2004 and FSX.
