FLIGHT International, I January 1977 35 How to cut your engine operating costs 20% without cutting corners. The CFM56. At a time when more and more airlines are looking for more effi cient ways to operate, along comes a powerplant that will dramatically cut engine cost of ownership. The CFM56. Compared to engines now powering standard-bodied aircraft, it's predicted the CFM56 will be 20% less expensive to operate on a seat mile basis. A considerable cost savings. Considerable, because the ad vanced technology CFM56 is a much more productive engine. It'll burn up to 23% less fuel per seat mile at cruise, for example. And be cause it's built on proven, mature design technology, the CFM56 will be easier and cheaper to maintain. Plus, it's also backed by a tougher test program than ever before to find and correct problems before the engine goes into service. The CFM56 is a 22,000 lb. thrust, bypass 6 turbofan for new and derivative twinjets, trijets and quad- jets in the 135-350,000 lb. takeoff gross weight class. Full-scale testing is already well along at both SNECMA in France and General Electric in the U.S.A. During 1976, in fact, six engines will be in the test program. The CFM56. It means being able to lower engine operating costs 20% without lowering standards of performance. cfm Q international, s.a. A JOINT COMPANY OF SNECMA. FRANCE AND GENERAL ELECTRIC. USA.
