A canard based air speed, angle of attack and sideslip measurement system consisting of canard mounted pressure transducers. The canard includes a leading edge, a side surface, a bottom surface and a top surface. The apparatus includes pressure sensors including a plurality of flush orifice pressure sensors mounted on the canard further including a first configuration of pressure sensors flush mounted on the side surface, a second configuration of pressure sensors flush mounted on the bottom surface, a third configuration of pressure sensors mounted on the top surface, and a fourth configuration of pressure sensors mounted on the leading edge and wherein each pressure sensors provides an output signal and the combinations of all of the output signals are proportional to the angles of attack of the aircraft. A shaft encoder provides displacement angles for the canard.
