An angle of attack sensor 10 includes a vane that is freely rotatable to align with a direction of an oncoming airflow over the vane. The airfoil 14 includes a root proximate a vane hub 26 that connects to a rotatable shaft 54, a tip opposite the root, a leading edge 44, a trailing edge 46 opposite the leading edge 44, a first lateral face 42A, a second lateral face 42B, and a heating element disposed within the airfoil 14 between the first and second lateral faces proximate the leading edge 44. The first lateral face 42A extends from the leading edge 44 to the trailing edge 46. The second lateral face 42B is opposite the first lateral face 42A and extends from the leading edge 44 to the trailing edge 46. The first and second lateral faces are symmetric about a chord 48 of the airfoil 14 and each have an outer surface profile that is nonlinear and geometrically convex from the leading edge 44 to the trailing edge 46.
