NATCA SBS continues to work wit h the Agency toward a more proactive appr oach to ADS - B avionics issues. Though these issues are rare, the Agency's approach to date has been hampered by a lack of resources devoted to investigating flagged issues with in the SBS Compliance Monitor. These is sues occur when standards for installation or configuration within aircraft or ground systems are not met. ADS - B is a cooperative surveillance source relying on the position information determined onboard the aircraft. In order to reduce or prevent the num ber of safety compromising events in the NAS we need a proactive, timely response. NATCA SBS is asking the Agency to reopen analysis of the risk associated with erroneous position in the ADS - B SRMD, and a meeting is planned in January. The frequency of is sues to date warrants more discussion on the topic. The Agency has indicated a non - compliant aircraft list may be developed, and this may be an appropriate mitigation for the risk. However, an SRM Panel is the appropriate place to make that determination. Advanced IM/FIM - S Met with American Airlines and ACSS on Nov . 29 to discuss another iteration of Merging and Spacing with hopes that is can be perform ed on Phoenix landing traffic. No commitments have been made by any parties involved as of yet. ConOps W ork group met the week of Dec. 5th. Focus for this meeting was primarily on Paired Approach. Advanced Surveillance - Enhanced Procedural Separation (ASEPS) Formerly known as Space Based ADS - B (SBA), formerly known as Reduced Oceanic Separation (ROS). A th ird SRMP was held Nov . 29 to Dec . 1 that included NATCA representat ives from all ATOP facilities. The previously identified 12 hazards were given initial and final rankings based upon mitiga tions identified by the Panel. NATCA and other SMEs continue to id entify enhanced oceanic communications as a necessary mitigati on for the hazards identified. Without enhanced communication the overall success of the ASEPS remains in question. ASEPS continues to explore a reduce d oceanic separation standard. This may be supported by Space Based ADS - B or with changes to ADS - C, currently used in ATOP. In any environment, including oceanic, separation standards are closely tied to the combined performance of communication, navigation, and surveillance. While SBA represents our dramatic change in surveillance, little is changing in the ability to communicate with aircraft. This affects response times and much more. NATCA ATOP SMEs have weighed in during our SRMPs that ADS - C backup is desired even with the introduction of SBA. ASDE - X Tech Refresh: Training meetings continue as the team updates the CBI. FLL MIA and MCO are the next facilities that will receive the tech refresh training. This training will take place early next calendar year. ASSC :
