Speaking earlier this year, 747 Chief Engineer Michael Teal revealed some insight into the new wings for the 747-8 family.
“The improvements in performance come from two large areas. One is the new aerodynamic wing that improves the lift over drag and also the engine. Because the engine and the wing are the same on both airplanes, the technology changes that increase the improvements for fuel efficiency you get on both airplanes. In terms of the percentage improvement, it’s different whether you’re measuring in tonne-mile costs on the freighter versus seat-mile costs on the passenger, and of course they fly different distances, that’s why you’ll see different numbers,” he said.
