1. An air active control aircraft comprising:

  • a three-dimensional true airspeed detection system including an air data sensor probe consisting of a truncated pyramid-shape Pitot probe and an air flight velocity operation processor for generating an air flight velocity vector signal from air pressure information detected in the three dimensions by said air data sensor probe;

    airframe motion detection sensors for detecting motion of an airframe; and

    an on-board control computer for generating a flight control logic,wherein said on-board control computer inputs said air flight velocity vector signal generated from said air flight velocity operation processor into a control-surface control system along with parallel inputs of airframe motion detection sensor signals generated from said airframe motion detection sensors to generate said flight control logic for carrying out the three-dimensional air flight stability control,wherein said on-board control computer stores airframe data obtained by a wind tunnel test, aerodynamic data and engine data to form a data base, selects data of said data base by inference, table look-up and interpolation for every flight configuration of takeoff, cruising and landing based on said air flight velocity vector signal and said airframe motion detection sensor signals, and generates said flight control logic.
