My Unsatisfactory Condition Report of Sep '88 addressed this issue and recommended that we implement the use of this software patch. In May '90 this patch was finally implemented for the first time in Cleveland Center. It was used for radar sort boxes over the Detroit, Cleveland, and Pittsburgh long-range radar sites. This was implemented to support CENRAP, wherein center radar data can be supplied to approach controls as an emergency backup should their airport surveillance radar fail. The sort box over Dansville wasn't adapted in this manner until after the Jan-Mar '92 issue of the Journal of Air Traffic Control, which reprinted my paper from the symposium.
