Eclipse Aviation Selected Pratt & Whitney Canada to be the Eclipse 500 Engine provider on February 19, 2003. Pratt & Whitney Canada created the PW610F-A engine, a PW600 Series engine, to be the Eclipse 500 engine. On May 5, 2004 Pratt & Whitney Canada completed the first run of the PW610F engine and completed it's first flight on board Pratt & Whitney Canada's Boeing 720 flying test bed on December 20, 2004. The Pratt and Whitney Canada PW610F became certified by Transport Canada and the FAA on July 27, 2006. The official name for the Eclipse 500 Engine is the Pratt & Whitney Canada PW610F-A engine. The PW610F-A is capable of producing 950 pounds of thrust (lbf). The PW610F was originally rated at 900 pounds of thrust, however Pratt & Whitney Canada created an updated version (PW610F-A) of the PW610F that produces more thrust. Just like the other PW600 series engines, the PW610F-A is made with half the parts of a conventional turbofan engine.
Two Pratt & Whitney Canada PW610F-A engines are mounted at the back of the Eclipse 500 very light jet. The Eclipse 500 engine is FADEC Controlled (Full-Authority Digital Engine Control), allowing for a lighter workload on the pilot flying the Eclipse 500. Also the PW610F-A has an automatic power reserve that allows for increased power, if one of the engines accouters a problem.
