further increasing the responsiveness. SBS Engineering is working diligently with Harris to incorporate these changes with additional EV parameters in 2018. With 2020 approaching rapidly, these changes are needed sooner rather than later, to limit the sporadic effects of non-compliant avionics. • SBS Article 114 work group discussions resulted in all B787 aircraft being placed on the NSAL. These aircraft had a latent avionics issue that causes false position information to be displayed to the controller. This alarmed several facilities and caused both SCT and NCT to demote ADS-B in their sort cell priorities. Boeing has since released a Service Bulletin to address the problem. Most of the B787 operators in the US have confirmed completing the Service Bulletin allowing them to be removed from the NSAL. Other B787 operators are being removed from the NSAL as verification of the Service Bulletin is received by Flight Standards. Advanced Interval Management (IM): • Discussions with American Airlines and ALPA surrounding Third Party Flight ID phraseology continue. The next meeting is scheduled for Oct. 25. • The Time-Based Spacing Demo to be held at MITRE this month has been postponed and is now scheduled for early November. • AIRS Working Group meeting is scheduled in D.C. the week of Sept. 17. ASEPS: • The Agency is now exploring a pivot to other potential areas where Space Based ADS-B could be beneficial. ZMA Caribbean airspace is currently the primary focus to prove this capability. This "pivot" away from ATOP means that Eric Labardini has taken a more prominent role in numerous ongoing discussions. • The Agency anticipates a favorable decision from a Joint Resources Council meeting on Sept. 20. Provided this occurs, the ZMA Caribbean effort will require a formal kickoff meeting and a follow-on SRMP. MEARTS Fusion: • 3nm Fusion in MEARTS is a complex undertaking requiring multiple Tower, Approach, and En route sectors to come online with Fusion at the same time. The lessons learned in this undertaking will help with future MEARTS and ERAM sites. • ZAN has been on Fusion since August 2015. HCF has been on Fusion since Aug. 1, 2017. ZUA transitioned to Fusion on March 26, 2018. • A Fusion kickoff meeting, Air Traffic Cadre, and some limited Fusion observations took place the first week of April at San Juan CERAP (ZSU). Analysis of the observations resulted in a need for automation changes. Software changes are now in place and a Fusion Operational Suitability Demonstration is scheduled the week of Sept. 24. Surveillance Portfolio Analysis Work Group • Eric Labardini and James Keith (NATCA AJV-7) have been working closely with the Agency's multifaceted analysis of post 2020 radar infrastructure needs. The ADS-B
