|Name:||Dynamic Ocean Tracking System Plus|
|Description:||The Dynamic Ocean Tracking System Plus (DOTS+) automation system is located in each of the three Oceanic Air Route Traffic Control Centers (ARTCCs), (Anchorage, Oakland, and New York) and in the David J. Hurley Air Traffic Control System Command Center (ATCSCC). The DOTS, upgraded and frequently referred to as +, permits airlines to save fuel by flying random routes, in contrast to structured routes, and permits the air traffic controller to achieve lateral spacing requirements more efficiently. The DOTS generates flexible oceanic tracks that are optimized for best airspace utilization and best time efficiency. Flexible tracks are updated twice a day using forecasted winds aloft and separation (vertical and lateral) requirements. The DOTS oceanic traffic display gives a visual presentation of tracks and weather. The DOTS sends traffic advisories and track advisories to users and receives aircraft progress reports from the commercial communications service providers (CCSP). These external data exchanges are achieved through interfaces with the National Airspace Data Interchange Network (NADIN) Packet Switch Network (PSN) for Position Reports, Air Traffic Management (ATM) messages, Pilot Reports (PIREPS), and the Anchorage FDP2000. An interface to the Enhanced Traffic Management System (ETMS) will improve coordination between the oceanic and domestic Traffic Flow Management (TFM) systems. The DOTS Weather Server, installed at the ATCSCC, receives National Weather Service (NWS) wind and temperature data via the Weather and Radar Processor Weather Information Network Server (WARP) system. The weather data is then distributed to the ARTCCs via commercially provided Integrated Services Digital Network (ISDN) telephone lines. DOTS Plus supports separation reduction initiatives as stipulated in RNP-10 (Required Navigation Performance) for decreasing lateral separation from 100 nautical miles to 50 nautical miles.
