An angle of attack sensor includes a vane that is freely rotatable to align with a direction of an oncoming airflow over the vane. The airfoil includes a root proximate a vane hub that connects to a rotatable shaft, a tip opposite the root, a leading edge, a trailing edge opposite the leading edge, a first lateral face, a second lateral face, and a heating element disposed within the airfoil between the first and second lateral faces proximate the leading edge. The first lateral face extends from the leading edge to the trailing edge. The second lateral face is opposite the first lateral face and extends from the leading edge to the trailing edge. The first and second lateral faces are symmetric about a chord of the airfoil and each have an outer surface profile that is nonlinear and geometrically convex from the leading edge to the trailing edge.
