ABSTRACT:
An aircraft navigational system includes a digital computer, a first visual output for displaying to an aircrew a geometrical representation of an optimum descent guideslope relative to a symbol representing the location of the aircraft, and a second visual output for displaying optimum descent guideslope information, such as altitude and distance, alphanumerically. The visual display provides guidance information to the aircrew to control the descent of the aircraft along an optimum descent guideslope which is referenced to a selected end of descent waypoint such as a destination airport or to an instrument approach marker. The guideslope is calculated in accordance with predetermined airspeed and altitude requirements with define a descent profile which is fuel efficient and which complies with aviation regulations regarding maximum airspeed limitations. The navigational system includes a keypad interfaced with the computer to allow the aircrew to enter data inflight to generate the visual and alphanumerical display of the optimum descent guideslope.
