lab in string 16 will be migrated to the Denver adaptation after the New Year. At the request of Second Level Engineering, we conducted analysis of previously reported problems with both the TBFM and STARS functionality. We provided this feedback to both Leidos and Raytheon. Some issues were corrected, and some remain outstanding. During the week, we also participated in several telcons regarding the Leidos PRs (Problem Reports) and Raytheon DRs (Discrepancy Reports). We were able to close some of the DRs and we ranked our top priority PRs, which will be installed with the next software adaptation build. Issues that relate to STARS software have to compete with future STARS enhancements and minimal bandwidth availability. This issue will have to be addressed at the Program Management level to ensure that IOC critical functions for TSAS are fixed. Update for the Week of Nov. 5, 2018 AIRSPACE Jim Davis (PCT) is the National Airspace Representative for NATCA. The reports from various airspace team leads and Mr. Davis are below: CLE/DTW Metroplex The CLE/DTW Metroplex project is moving into the post-implementation evaluation and modification phases. We have identified and modified several LOAs and created temporary procedural fixes until more permanent solutions can be implemented. We have begun working with the POCs from DTW, D21, CLE, and ZOB, along with industry representatives on SID and STAR concerns. Specifically, discussions were initiated regarding SID design to eliminate the use of "Climb Via Except Maintain" clearances, on the Detroit procedures. To do this we needed to resolve crossing altitude clearances on several of the SIDs. These crossing altitudes are the issues that led to the current open SID design. Working with all parties, the team was able to evaluate current aircraft performance, and very slightly change a fix location to allow industry to have confidence that the altitude restrictions were achievable. With this issue resolved, the team then proceeded with re-connecting the open SIDs and making any other changes needed to establish a "Climb Via" to a published top altitude of 170. A database for the proposed changes was delivered to Delta to use for validation testing. The team also reviewed known issues with STARs and captured Delta's feedback on our tracker list. An issue was identified where aircraft FMS's are operating outside the parameters of the STAR design by slowing their airspeed long before required, and below the published speed. No specific solutions have been identified to correct this issue, and it may be beyond the ability STAR design/modification to correct. The CLE area SID and STAR modifications were discussed, and proposed changes will be discussed the week of Dec. 4.
