Cessna Citation Columbus

The Cessna Citation Columbus, designated Model 850, was a large-cabin business jet that Cessna launched in February 2008 and cancelled in July 2009 before any example was built. It was planned as the largest member of the Citation family, with twin Pratt & Whitney Canada PW810 turbofans of 8,830 pounds-force thrust each, a 30 degree swept wing of 709 square feet, room for ten passengers and a target range of 4,000 nautical miles with eight aboard. Cessna began market research in 2002, showed a cabin mock-up in October 2006 and planned certification by the end of 2013, with the cockpit to feature synthetic vision and optional head-up display. Cessna suspended the programme in April 2009 and formally cancelled it in July 2009 after reviewing the business jet market, and Textron wrote off about 43 million dollars. Pratt & Whitney Canada stopped the PW810 engine but continued the PW800 series.
