An aerodynamic force sensing apparatus for providing an air data computer with information to calculate air data. The apparatus includes a plurality of vanes supportable in a vane array extending from a distal end of an airfoil of an aircraft, and one or more sensors configured to sense the response of one or more vanes of the vane array to aerodynamic forces and to transmit corresponding signals to an air data computer (ADC) for use by the ADC in calculating air data.
