The Japanese opted for the geared turbofan on account of its 15 percent lower operating costs. “A major part of that is due to its lower fuel con- sumption,” Winkler says. Compared to today’s best-selling engines in this thrust class the new design offers a reduction of maintenance costs of 40 per- cent according to Robert Saia, Vice President Next Generation Product Family at Pratt & Whitney.
