The Learjet 45 is a midsize business jet built by the Learjet division of Bombardier Aerospace. It was the first all-new design since the original Learjet, and with its four main versions, the Model 45, 45XR, 40 and 40XR, it was Learjet's main product from the 1990s until the Model 75 arrived in 2012. In the U.S. there are 427 with a valid registration.

History

Learjet developed the Model 45 in the 1990s to compete in the "super-light" business jet class against the popular Citation Excel, giving up the Cessna's stand-up cabin for the Learjet family's traditional high speed. Every earlier Learjet had grown from the first one, the 1963 Model 23; the 45 was the company's first clean-sheet design since then.

Design

In size it sits between the smaller Learjet 31 and 40 and the larger Learjet 60. It offers the running costs of a light jet with the performance and comfort of a midsize one, flying 1,971 nmi at Mach 0.81 with four passengers. The cabin has a flat floor and a non-circular cross-section for extra headroom.

The Learjet 45XR, introduced in June 2004, allows 1,000 lb more takeoff weight, cruises faster and climbs faster, mainly through engine changes, and needs unusually short runways for a midsize jet.

Registered in the United States
