scheduled the week of April 1. Once the suitability testing is passed and completed, coordination with the sites to upgrade their systems will begin. The issues from CLT have been found, and Terminal Second Level Engineering (TSLE) has been working on a patch that will limit the number of updates the system received from ATD2. • CLT – Final coordination with the site to install the patch mentioned above, is underway with late January being the target date. Until then, most of the updated times from ATD2 are off so the system remains stable. • PHX – Nothing new. • CLE – Nothing new. • LAS – Nothing new. SWIM Visualization Tool (SVT) – VOLPE demoed the new SVT share capability via web meeting to the Houston-area facilities. This modification in capabilities was requested by the facilities to mirror and possibly replace their current Aerobahn operations. That determination has yet to be made, as the facilities need time to work with and gain comfortability with SVT in order to determine if it will be able to replace their current systems. For S46, the facility is still working on procuring the necessary monitors to display SVT near the departure walls in order to gain the most benefit out of the system. Currently, it is being displayed in the TMU area, and it has been updated to now showing the baseline five-second update rate, as opposed to the training five-minute delay they had previously been testing. TIME BASED FLOW MANAGEMENT/TERMINAL SEQUENCING AND SPACING (TBFM/TSAS) Matt Gammon (ZID) is the Article 114 Representative for TBFM/TSAS. His report is below: The week of Dec. 3, members of the TBFM Ops Team visited the Tech Center to work on Sustainment Testing. Along with assistance from Tech Center personnel and Contract Support, these sustainment activities have helped to identify issues in the interim builds and helped improve the TBFM product that gets delivered to the field. As sustainment has been identified as the top priority for the TBFM system, these reoccurring tests have begun to provide valuable feedback to the engineers and testers that deliver new releases. A meeting was held at ZOB to discuss early departure scheduling from PIT into the PHL arrival TBFM system. Evaluating early departure scheduling into an arrival system in the Northeast corridor is a milestone as part of the Trajectory Based Operations (TBO). The intent is to see if there are benefits in having towers call early for departure releases into a TBFM arrival system in the Northeast Corridor (NEC). Representatives from ZOB and PIT were involved in this meeting and a follow-up to this will be held at PIT in January.
