• ADSB Fusion Display Management – NATCA SBS Article 114 Rep Eric Labardini briefed the team on Fusion Display, which is defined as a system that is capable of receiving surveillance reports from multiple sensors of different types and combining those surveillance reports into a single track for each aircraft. This technology will provide a more rapid track initiation and faster update rates that equate to more accurate positions and velocity estimates to be displayed to the controller. The following issues are examples of what the National User Team worked prior to Dec. 21, 2018: • A185525 IPOD Parameter for Inter-Facility Point Outs – The AIMS ticket was discussed. It identifies an issue involving the IPOD Parameter for Inter-facility Point Outs. The parameter value was briefed and what affect lengthening or shortening it would have. The site in question was attempting to make a point out for a flight whose old point out was still being retained by the system. • Altimeter CAR – The team discussed the CAR and its request to evaluate the current capability of one-minute updates for Weather and Altimeter. There was concern expressed about having the weather update so frequently, and for a certified observation being overwritten by an automated update. The team will continue to work this issue and determine an appropriate response after receiving more analyses. • ER 186070 Weather Update – The team discussed the ER and worked on problem statement language, "The current desired behavior is, should the age of a weather report exceed an adaptable center-wide parameter (nominally 120 minutes), the weather will be declared missing and will immediately reflect '-M-'." This would be consistent with the current Altimeter functionality. The team will continue discussion of the problem statement to ensure there will not be an issue with other needed weather information. • Hand-off to Non-U.S. – The updated use case reflects several changes made as a result of incorporating DataComm into the ongoing engineering in support of automated handoffs to Canada. • SE2 Use Case Updates o Airspace Transfer – The team discussed and reached consensus on an updated use case adding changes to clarify the TAS menu and view behavior requested by the task team. o Point Out – The team discussed and reached consensus on an update to the use case that added clarifying language for Auto Point Out and Point Out Data Block behavior.
