A vertical tail for use with an aircraft or other form of mobile platform. The vertical tail includes a main element which is fixedly secured to the mobile platform, and a leading edge element that is movably secured to the main element. The cross section of the leading edge element is symmetric about the cruise chord line of the tail. The leading edge element can be pivoted and/or extended to create a gap with the main (fixed) element. The movable leading edge element is used to increase the maximum yawing moment provided by the vertical tail. The maximum yawing moment is increased when air flow is incident from either side of the vertical tail.
