during heavier volume periods. The team was able to look at these changes as well as start to look at the other underlying adaptation with the local ZNY Automation Staff helping. Most of the configurations needed slight adjustments which N90 specialists recommended and we all believe that overall the EWR internal (TRACON) TBFM architecture has been updated to emulate the actual operation as close as possible, which is the goal. The next step for the update of EWR arrival metering is to meet with the adjacent facilities and go over their specific architecture (ARC placement, delay distribution) and make sure that it is up-to-date as well. The team additionally took an early look at N90's LGA metering setup and we discussed recommendations for future work on that system. Additionally, the same week members of the Ops team working on TSAS were at ZAB working with representatives from ZAB and Phoenix TRACON (P50) on their LOA changes necessary for TSAS as well as other identified items needing to be addressed prior to IOC. A lot of topics were discussed and worked on through the week including staffing, impacts to internal departures, TBFM tools necessary for +/- 30 second delivery to the TRACON as well as a number of other topics. It was identified that having TBFM SMEs at P50 in the future would be helpful in continuing to identify and help with issues leading up to TSAS IOC. On the last day of meetings two Ops team members visited ABQ Tower to conduct an IDAC Pre-site survey. These initial surveys are used to explain IDAC to facilities and then get input as to where they believe the equipment should be installed. The week of Jan. 15, Ops Team members were at ZLA testing the first IDAC TRACON adaptation with representatives from ZLA and SCT. The adaptation that was delivered was tested in the Support Lab at ZLA and seemed to be working as expected. There were a number of discussions about training, equipment, and other items that need to be addressed for rollout into operational use. A training/implementation week was set for February and Ops Team representatives will be at ZLA and SCT for this activity. The same week MITRE held TBO Scenario Walk through scenarios in which Ops Team members participated and there was a TSAS Early User Interface that was held at the Tech Center. As TSAS development continues it will be important to get as many eyes on the system as possible because there are a lot of questions being asked to Operation personnel on how the system should work. The remainder of January the Ops Team will be at ZAU to finish adaptation work on their En Route Departure Capability, Atlantic City to test the upcoming 4.8 system release, PHL TRACON to take an initial look at their PHL arrival metering system, and perform IDAC Pre-Site surveys at ELP and TUS. WAKE TURBULENCE John Murdock (PHL) is the Article 114 Representative to the Wake Turbulence Office for NATCA. His update for the week is below. In January, NATCA participated in a SRM Panel for the proposed consolidated wake turbulence separation standard. The panel did not complete the SRM process. During the panel, there was much discussion about lack of reports and reference data to make decisions with. Also, the proposed wake turbulence separation changes were amended
