What goes down, can come up, according to Cessna. Earlier this year, the manufacturer revised its sales projection downward after fractional operator NetJets aborted a large order for the companyís Citations. Now, however, Cessna says new orders it has received so far in 2004 will allow it to recoup those losses, and then some. Instead of 165 to 170 new jets, the company expects to deliver 170 to 175 during the year. And, in 2005, Cessna plans to ship some 200 Citations. By comparison, Cessna delivered 197 jets in 2003. Cessna "blames" the potential new business on what it sees as improving economic conditions -- and no one discounts the continuing decline of airline service as a major force behind business aviationís potential. Finally, a number of incentives -- from domestic RVSM to tax breaks -- exist to buttress new-plane sales. All anyone really needs now for the market to break wide open is the "next big thing."
