Clatfy Assistant Examiner.l an S. Black Attorney-S. C. Yeaton ABSTRACT: Apparatus for providing a contact analog display on a cathode-ray tube representing the horizon, ground plane grid lines in perspective, and a runway or other flight path reference in perspective, by intensity modulating the electron beam of the cathode-ray tube while it traces out a spiral raster. Center reference indicia and flight director bars may' be generated during the retrace time of the raster.
