Cessna Aircraft painted a picture of its mixed fortunes at its NBAA press conference today, with CEO Scott Ernest saying the company was making good progress on its marquis development programs–the new Citation Latitude and Longitude–while acknowledging problems with single-engine piston products and continuing quarterly financial losses. Cessna posted a $23 million loss in the third quarter as deliveries of its jets for the period dropped to 25 from 41 in the same period a year ago.
