Learjet 40/45 Information

Learjet 40
The Learjet 40 is a shorter cabin version of the Learjet 45.  It was designed to replace the Learjet 31.  The cabin is 4 1/2 feet longer than the Learjet 31 and it has more head and shoulder room.  The cabin has a galley and a full aft lav.  The cockpit has a Primus 1000 integrated avionics package and the TFE731-20 engines are full FACEC.  First flight was August 2002 and deliveries began in 2004.

Learjet 45
The 45 is of classic Learjet design and layout. However a number of key design changes were made early into the 45's design life including a larger fin and rudder, extended engine pylons, smaller delta fins, full span elevators, and single piece flaps.

Larger than the Learjet 31 and smaller than the 60, Learjet states that the 45's 1.50m (4.9ft) high and 1.55m (5.1ft) wide cabin will provide more head and shoulder room than any other aircraft in its class.  The cabin is designed to accommodate double club seating, a galley and a full width aft rest room, while eight windows line each side of the cabin. The flight-deck features a four screen (two primary flight displays and two multifunction displays) Honeywell Primus 1000 integrated avionics suite.  While an APU is standard, many aircraft were produced without an APU.

The -20 FADEC equipped version of the proven AlliedSignal TFE731 engine was developed in cooperation with Learjet for the 45 and incorporates 60 design changes to increase fuel economy and reduce operating and maintenance costs. While Learjet retains overall 45 program leadership, and is responsible for the aircraft's design, other Bombardier Group companies participate in Learjet 45 production. De Havilland Inc in Canada is responsible for wing construction, while Shorts of Northern Ireland in the UK builds the fuselage and empennage.
