of essential services (TIS-B and FIS-B) NAS-wide, and other ADS-B related programs activities. An ADS-B "Out" Notice of Proposed Rulemaking (NPRM) was also published. Key remaining Segment 1 implementation milestones are: 1. Complete deployment and certification of equipment to support service delivery in selected locations 2. Certify ADS-B as an approved surveillance source to support existing separation standards on five FAA automation platforms - ERAM, HOST, MEARTS, STARS, and CARTS 3. Publish ADS-B "Out" Final Rule 4. Confirm minimum avionics performance to ensure future utility. 5. Define additional aircraft to aircraft requirements 6. Achieve early benefits in non-radar airspace ADS-B critical services (ADS-B downlink to ATC for separation) will be implemented at four key sites (service volumes): the Gulf of Mexico; Louisville, KY - Terminal Radar Approach Control (TRACON) and UPS GOC; Philadelphia, PA - TRACON; and Alaska Anchorage Center and Juneau Air Traffic Control Tower. SBS - Segment 2: SBS capabilities will be activated in the remaining NAS service volumes with plans to complete NAS-wide deployment of ADS-B by 2013. The ADS-B "Out" Final Rule for broadcast will be published during the end of Segment 1 and beginning of Segment 2, providing an equipment baseline to continue user equipage and application development and deployment.
