identify possible traffic management problems by calculating and monitoring actual and predicted delays and displaying alerts when user - specified thresholds are exceeded. § Enhanced Sector Alerting Metric wil l provide an enhanced sector alerting mechanism based on patterns of minute - by - minute traffic demand, rather than on a single peak minute. § Status of TFMS Execution will indicate TFMS execution status by providing traffic managers with the up - to - date stat us of newly modeled events . · WET Update: o The WET team is working on developing new guidance for the CAWS (Collaborative Aviation Weather Statement) and CCFP (Collaborative Convective Forecast Product) . o The CAWS will only be issued when its either correcting the CCFP and the issue has an impact on operations that would or could result in TMI¹s. A flowchart is being developed to help the Aviation Weather Center forecasters in issuing the CAWS. In addition , CAWS are meant to be more focused and not b road brushed areas. The goal is to have them issued in the 2 - 4 hour window so that decisions on TMI¹s can be made timely. Training for CAWS is being revamped and will be more in - depth. The plan is to finalize training toward the end of January. · FET Update: o Enhanced wind models being developed to help with concepts of RTA for TBFM. o Background on "Integrated Descent Manageme nt" (IDM) Concept for NASA/FET. o Introduction: For the past several years, researchers at NASA Ames have been investigating s pecific problems affecting traffic flows travelling to and from New York. This research effort, called "New York Trajectory Based Operations" (NY TBO), leverages new NextGen trajectory management technologies developed by the FAA, NASA and others to provid e a toolkit of integrated solutions to these problems. A current focus of NY TBO, called " Integrated Demand Management " (IDM), operationally integrates the Collaborative Trajectory Options Program (CTOP) with Time - Based Flow Management (TBFM) and required - time - of - arrival (RTA) clearances to address equal, throughput and delay issues associa ted with NY arrival operations. o Problem: Newark Liberty International Airport (EWR) was chosen as the test case for IDM development. EWR routinely has arrival demand at or near capacity with a varying mix of short - haul and long - haul flights. Arrival demand is reasonably well managed with miles - in - trail (MIT) and TBFM metering; however, close - in departures often experience excessive and unpredictable ground delay w hen the overhead flow is full. § Solution: IDM uses three key technologies to improve EWR arrival flow management: TBFM to "tactically" manage delivery to a capacity - constrained airport, CTOP to "strategically" manage demand into TBFM, and CTOP -
