An axillary airfoil located as far forward as practicable on the fuselage of an airliner. During high speed cruise, the airfoil can be adjusted to provide supplemental lift to move the center of pressure forward, thereby reducing the amount of downforce needed to be produced by the vertical stabilizer. This would result in saving fuel. Spoilers mounted on the airfoils would be programmed to automatically deploy to return the center of pressure rearward whenever flight conditions require greater longitudinal stability.
