ENROUTE AUTOMATION WORKGROUP (ERAW) Julio Henriques (ZNY) leads the ERAW efforts for NATCA. Rex Jackson (ZDC) provides this update. Numerous FTRs supported ZKC's initial Data Comm Functionality Verification (DFV) testing. The testing was very successful with limited software issues identified. The FTRs will continue to support the testing at ZID and ZKC as Data Comm deployment moves forward. ZME was scheduled to enable CPDLC for the first time on the July 29, 2018 mid shift. EAE120 completed Ops Eval testing and was released for keysite testing. Initial TTL testing at ZLC discovered two issues that require a rebuild of the EAE120 software. AIMS 193548 AT Position Keys 52 and 53 no longer work as a space key when neither key is adapted as "Data Comm Key" (/U). AIMS 193560 Data block Leader Line displaying incorrectly when pointing North with 4th line data. The new version of EAE120 was Ops Eval and keysite-tested the week of July 23. ZLT and ZID are the TTL test sites for the new software and ZTL was scheduled to begin operational testing on July 31. The following issues are examples of what the National User Team worked: EDST Point Out Issue The team discussed and reached consensus on the problem statement. Its desired behavior is to create a system timer for cleanup of Point Out Field Indicators for specific types of flights. Data Comm Enhancements The team discussed and prioritized the Data Comm future enhancements. The priority list was sent to the team for further review and input. Non-U.S. Centers vs. Terminals Data Comm briefed on a solution for properly identifying non-U.S. centers versus terminals in transfer of communication messages. The team agreed with the proposal and the use case will be updated to reflect the new behavior. SE2 Use Cases There was a discussion of the fourth line and Point Out use cases. For fourth line, the team agreed to add language for system behavior when entering a Unique Syntax "QS T" message without track control. For Point Out, the team agreed to add language for system behavior for Point Outs as it relates to the settings of the fourth line switches. ER 182677 Route Amendment Causes Red X The team discussed the possible solutions for the ER. The team agreed that the smaller engineering solution is the correct fix, rejecting amendments that cause trajectory- modeling failures.
