Production of Cessna Aircraft’s new Citation Latitude is on schedule, and the company expects that full airframes will be on the manufacturing lines by year-end. The midsize business jet is scheduled to fly in the first quarter of next year. The Wichita-based aircraft manufacturer has already started building test articles, and has moved from engineering, analysis and modeling to cutting metal. Meanwhile, Cessna started a 19-city tour in the U.S. last week that showcases a Citation Latitude cabin mockup. The tour arrives in Atlanta tomorrow and will end on June 14 in Oklahoma City.
