Citation XLS

The XLS is the updated version of the Citation Excel and goes faster and further than its predecessor. The XLS can climb to its flight level of 43,000 feet in just twenty five minutes (8 minutes faster than the Excel) and can cruise at 428 knots. The XLS can reach a range of 1,800 nautical miles with four passengers. It can take off on runways as short as 3,500 feet – the shortest takeoff distance of any midsized jet. The XLS outperforms competing private jets due largely to its two Pratt & Whitney PW545B engines. They are designed with a high-pressure core to increase thrust to 3,975 pounds apiece (4.5 percent more thrust than the engines used in the Citation Excel). Additional air flow through the engine’s core allows the engines to operate at higher temperatures. A Teflon seal was added to prevent oil leaks, and the single-channel electronic control engine allows the pilot to configure fuel flow at the beginning of flight and leave the system to do the rest during flight. Manual fuel control remains available for emergencies. These engines can reach .80 Mach uninstalled and have a specific fuel consumption of just 0.709 pounds per hour.
