ABSTRACT:
A template, for use in conjunction with a radar presentation to train an intercept controller in coordinating aircraft movements, defines spatial relationships between aircraft symbols presented on the radar through range and separation scales and position cues imprinted on the template. The template also has a series of apertures which allow direct marking of aircraft position on the radar scope without removing the template.
