1. A navigational aid system for providing correlated informational data in a form facilitating the operation of a craft, said navigational aid system comprising:

  • means for determining the status of at least one external physical condition independent of the operation of the craft but having significance with respect to the operation of the craft and producing first output data indicative thereof;

    means for determining the status of at least one internal physical state of the craft independently of said external physical condition status-determining means and producing second output data indicative thereof;

    means providing a surface characteristics representation of a selected portion encompassing an area of the surface of the earth related to the position in which the craft is disposed;

    data processing means operably coupled to said external physical condition status-determining means, said internal physical state status-determining means, and said surface characteristics representation means for automatically correlating said first and second output data with said surface characteristics representation to produce combined correlated output data significant to the continued operation of the craft; and

    data presentation means coupled to said data processing means and responsive to said combined correlated output data produced therefrom to provide a presentation of said combined correlated output data in a unitary format readily comprehendible by an operator.
