Eclipse is challenging its competitors to post as detailed an aircraft development tracking progress as has been introduced online for the Eclipse 500 very light jet. The Albuquerque, N.M. company’s “Track Our Progress” feature at www.eclipseaviation.com lists more than 200 tasks and milestones leading to FAA certification in early 2006 and European certification in late 2006. Each milestone has a due date and eventually the actual date each goal is achieved. “We welcome our competitors to provide the same level of information about their development programs,” said Eclipse president and CEO Vern Raburn. One of the key target dates the tracking feature reveals: first flight of an Eclipse powered by the Pratt & Whitney Canada PW610F is December 31.
