• CLE – Training for build 5.4 was completed in late February and the site is now operational. An issue with this build was found recently where the gate assignment field on the strip is now sorting improperly, causing the controllers to have to scroll unnecessarily to find a gate. A patch is being worked on at the Tech Center and will be tested and installed as soon as possible. • LAS – We're still working with LAS to schedule the updating of their training system and a visit to help adapt that system to their liking. Once they have that capability, they will decide whether to use AEFS operationally or wait for TFDM. • SWIM Visualization Tool (SVT) – There is nothing new to report with SVT. TIME BASED FLOW MANAGEMENT/TERMINAL SEQUENCING AND SPACING (TBFM/TSAS) Matt Gammon (ZID) is the Article 114 Rep for TBFM/TSAS. His report is below: TBFM Ops Team members traveled to the Leidos Lab in Atlantic City, N.J., to evaluate the future 4.8.4 TBFM system. The 4.8.4 system was looked at previously and will continue to be evaluated at the Tech Center, as iterations are delivered. The two main additions to the system that 4.8.4 provides to TBFM is in reference to IDAC. The 4.8.4 system will deliver the capability for IDAC facilities to utilize multiple IDSTs in the tower. Previously there was unwanted behavior when facilities tried to use two different IDSTs at the same time. These issues were identified and have been fixed in the 4.8.4 system. These fixes and other changes were tested at the Leidos Lab and will continue to be tested prior to national release. That same week, Ops Team members were at the Tech Center working on the PHL TBFM system demo that will be supported by multiple labs. The work at the Tech Center was not only adaptation work for the future PHL system, but also ensuring that the labs are working together. This was an opportunity as well for more Ops Team members to get familiar with the setup that will be used for the eventual demo. The work that Tech Center personnel have done to set up these labs has been exceptional and without their help the ability of getting a demo ready for the facilities would not be nearly as far along. NASA Ames presented a demo of some TFMS/TBFM integration tools the same week to Ops Team members at San Jose. These tools are for possible future use and the general idea is to see how TBFM and TFMS may be used together to ensure not only proper distribution of delay, but to also ensure aircraft do not get delayed multiple times because the two systems are not communicating. Some members of the NEC/iTBO leadership will be visiting NASA Ames the week of March 18 to see this demo. During the week of March 4, TSAS SMEs from the TBFM Ops Team met at OKC to discuss future work for TSAS. Paul Carroll's report on this meeting is below. During the week of March 11, TBFM Ops Team members traveled to ZTL this week to support the newest 4.8.3 P1 Release. This is a release with an updated patch that was created to address issues that were initially found at the first keysites, ZID and ZTL. This new release was also tested at ZID at the same time to ensure that new connectivity capabilities work correctly. As the TBFM system continues to tie more facilities together utilizing not only traditional Adjacent Center Metering, but also capabilities like Extended Metering, the releases have to be fully evaluated at multiple sites instead of just singular sites. This system was initially loaded in both the ZTL and ZID support strings and evaluated before it was then loaded on the Operational String. There was one issue that was found that created ETA jumps, but an adaptation fix was found, and a ticket was created to ensure that the issue is permanently fixed.
