This jet, introduced in 2007, evolved from the Learjet 60, which entered service in 1993. The XR added an upgraded Rockwell Collins avionics suite in the cockpit, computer management for the engines, and new features in the stand-up cabin. The seats now fold flat for berthing on long trips, the lavatory is brighter (thanks to a window), and the three-seat divan and a galley are offered in various configurations to make better use of the space. Pratt & Whitney PW305A engines push the 60XR to a climb rate of 6,000 feet per minute, making it easy to reach the higher altitudes where fuel burn is most efficient.
