The system was tested on the operational floor at the Denver Air Route Traffic Control Center in September 1997. It was found that controllers using CPTP-aiding resolved many conflicts by issuing a direct-route clearance to one of the aircraft. A direct route often resolved a conflict well before it became tactical, gave the aircraft a short-cut, and required one less controller clearance. The potential for a three-fold increase in direct ...
