B Out. This breaks down to 12,329 with 1090ES avionics, 4,319 with UAT avionics, and a few hundred with both. UAT is only allowed per FAR to be used below Class A airspace, and 1090ES can be used in all airspace. o SBS RIO B oard: Reviewed multiple risks being tracked b y SBS on a variety of programs. NATCA offered input on the risks surrounding the lack of consistent filing of ADS - B information via the ICAO flight plan and the associated risk due to a lack of adequate displa y of the info to the controller. ADS - B information display on flight progress strips is needed for multiple facilities. o CLT WAM Engineering telcon: Feeds from the CLT ASR, ARSR, and WAM are now available at the Tech Center for evaluation. Configurat ion of the two Virtual Radars is operating as desired. ISAT (Initial Site Acceptance Testing) flight tests are planned for next week but contingent upon the ability to record data at the Tech Center. Despite technical successes, schedule risks for the SR MD and associated Order remain high. o CLT WAM SRMP: This second meeting of the panel was to discuss the likelihood of already identified risks. The Panel's previous meeting identified the potential severity. SBS believes that SMS 4.0 calls for analyt ical data to determine likelihood, not necessarily the Panel. NATCA objected to this approach and further discussion during the meeting resulted in clear cases where the likelihood ranked by the an alysts was much too optimistic. In addition, the Panel id entified a need for further discussion on monitoring of the WAM service at CLT. o ROS ConOps telcon: Discussed minutes from last week' s Space Based ADS - B (SBA) SRMP. AJV - 8 representative expressed the position that controllers will be expected to use S BA for conformance monitoring. NATCA believes that system modification is needed or the high update interval will only cause the ATOP controller to disable the optional SBA feeds during close to minimum separation operations. Discussed the potential haza rd of o verloading sector que messages. Discussed ADS - B intent data availa ble but not required in the US. This includes: autopilot selected altitude, autopilot selected heading, and altimeter pressure setting. o SBS Article 48 Work Group meeting: This month's dial in meeting touched on a number of topics: o Space Based ADS - B: Discussed the already mentioned challenges identified in last week's SRMP. o In Trail Procedures: SBS would like to conduct another survey of ZOA controllers prior to ATOP au tomation changes. The intent is to characterize the application before and after the change. A formal request is being generated. o CLT WAM: A regula r topic for the SBS Article 48. Discussion centere d on the risks in the schedule. All are working di ligently to reach an IOC by the end of March 2016. o ASSC: As mentioned in Dan Hamilton's update, the Agency has finally given direction to include the Surfac e Movement Radar (SMR) in ASSC. The Agency hopes to remain close to their spending baseline by reducing the number of MLAT Radios and/or identifying a lower
