A hierarchy of symbolic displays with increasing information content superimposed on a TV video terrain image is developed as an aid in approach and in precision hover. The most sophisticated configuration required ground position information. To obtain ground position information, a position sensor which utilized a ground beacon radio such as the Electronic Location Finder ELF was simulated. The position information was shown to be necessary to obtain hover precision of less than five feet. Aircraft stabilization equipment ASE was also found necessary. Author
