Abstract:
A method and system for creating a precision approach for an aircraft to a position on the ground from a location above the ground is disclosed. The system comprises a display unit onboard the aircraft that displays a digital moving map, a database onboard the aircraft that contains digital terrain elevation data and obstacle data, a global positioning receiver that identifies the in flight position of the aircraft and an input device use to select the position on the ground displayed on the digital moving map. A processor that is also onboard the aircraft is communicably linked to the display unit, the database and the global positioning receiver. The processor generates the digital moving map on the display unit from the digital terrain elevation data and obstacle data and creates an approach derived from global positioning system data for the aircraft to the position on the ground selected on the digital moving map based upon the in flight position of the aircraft.
