Cessna on August 13 said it completed a series of wind-tunnel tests for its large-cabin Citation Columbus. Results from the tests in low- and high-speed wind tunnels will be analyzed in the coming months, though Cessna said that preliminary data analysis revealed no surprises. The wind-tunnel facilities are located in San Diego and Toulouse, France. The $27 million Citation Columbus is slated for FAA certification in late 2013, with deliveries beginning in 2014.
