Improving the fuel efficiency of airplanes does not necessarily require innovative propulsion or highly unusual designs. In this work, we demonstrate with numerical examples that a three-surface configuration with redundant longitudinal control, obtained via two movable surfaces located on both the horizontal tail and canard, can be significantly effective in increasing the lift-to-drag ratio.
