Summary:An aircraft nose gear-mounted flight control device promotes aircraft stability during low-speed phases of flight, including take-offs and landings. The flight control device is an operable airfoil secured to an aircraft nose gear, either to a vertical support strut or to a wheel axle thereof. The airfoil is deployed when the nose gear is deployed, and is retracted when the nose gear is retracted. Upon deployment, the airfoil is effective to at least provide aircraft pitch control. In some configurations, the airfoil deploys as two separate but mirror-imaged left and right airfoil components that move in concert to provide pitch control. In other configurations, the airfoil components move at relatively different angular rates and amounts to provide both pitch and roll control. The entire airfoil may be pivotal for pitch control, or may instead be fixed, but have moveable flaps or flap-like portions that provide pitch control.
