Boeing yesterday announced a series of planned improvements to its 737 line the company says will result in a 2-percent decrease in fuel burn and a marked upgrade in cabin comfort and utility.

Boeing estimates it will achieve half of the fuel burn improvement through drag-reducing changes to the airframe, while the other half comes from hardware changes to the airplane’s CFM56 turbofans. Aerodynamic improvements include refined wing control surfaces, a wheel-well fairing redesign, a re-shaped anti-collision light and an ECS inlet/exhaust modulation.
