1. Apparatus for providing guidance information to an aircraft pilot, the aircraft having an attitude, location and motion relative to the earth, in the form of a conformal head-up display (HUD) which comprises:

  • means for generating an aircraft symbol on the display that simulates the attitude, location and motion of the aircraft relative to the earth;

    means for generating symbols that simulate on the display selected ground cues in position and orientation which superimpose over actual selected ground cues as seen by the pilot when they are visible through the display; and

    means for generating an aim symbol that is positioned on the display to provide a reference to which the aircraft symbol is directed for proper operation of the aircraft in selected flight modeswherein lateral guidance control error is displayed to the pilot by the angle said aircraft signal is deflected laterally relative to a desired touch-down point on a visible runway.
