This paper presents the theory and a description of a course-line navigation computer for use with the presently available vhf omnirange navigation system or with the proposed complete omnirange-dme navigation system. A position fix may be obtained with the equipment by triangulation using line of bearing information from two omniranges. A further computation then produces course and distance indications with respect to an arbitrary ground point as selected by the pilot. Alternatively, position-fix information derived from an oange-dme ground station may be used as input data for course-line computation. The punched-card reference-data system and pictorial course display instrumentation associated with the computer are described.
