aileron - an airfoil that controls lateral motion

device - an instrumentality invented for a particular purpose; "the device is small enough to wear on your wrist"; "a device intended to conserve water"

elevator - the airfoil on the tailplane of an aircraft that makes it ascend or descend

flaps, flap - a movable airfoil that is part of an aircraft wing; used to increase lift or drag

horizontal stabiliser, horizontal stabilizer, tailplane - the horizontal airfoil of an aircraft's tail assembly that is fixed and to which the elevator is hinged

leading edge - forward edge of an airfoil

rotary wing, rotor blade - the long airfoil that rotates to provide the lift that supports a helicopter in the air

rudder - a hinged vertical airfoil mounted at the tail of an aircraft and used to make horizontal course changes

spoiler - a hinged airfoil on the upper surface of an aircraft wing that is raised to reduce lift and increase drag

spoiler - an airfoil mounted on the rear of a car to reduce lift at high speeds

stabilizer - airfoil consisting of a device for stabilizing an aircraft

trailing edge - the rear edge of an airfoil

vertical tail - the vertical airfoil in the tail assembly of an aircraft

wing - one of the horizontal airfoils on either side of the fuselage of an airplane
