SAFETY AND TECHNOLOGY DEPARTMENT AIRSPACE TECHNICAL DEMONSTRATION 2 (ATD-2) Pete Slattery (CLT) represents the membership as the Article 114 Representative for ATD-2. His report for is below. October Shadow Engineering Sessions at the CLT ATD-2 Lab had members from ZDC TMU, as well as CLT airport Ramp personnel participate in order to observe how the system will impact their operations. On Oct. 19th and 20th, TMU workforce members from Washington Center (ZDC) met with CLT ATCT, FAA HQ and NASA personnel in the Charlotte ATD-2 lab for the 4th ATD-2 shadow session. Oct 19th was dedicated specifically to help ZDC ramp up on the latest ATD-2 tools and shadow evaluation process. On Oct 20t the team agreed on the TBFM/ATD-2 integration plan as well as the airspace scenarios that the electronic coordination technology would likely be used. Strong collaboration and fast progress in this meeting resulted in ample time for system shadow scheduling. ATD-2 shadow testing was the focus of the afternoon session. On Oct. 20th, workforce members of CLT ATCT, AAL CLT ramp, CLT airport ops, FAA HQ and NASA met in the Charlotte ATD-2 lab for a follow up session on 'data exchange and integration'. The focus of this session was on recapping the progress made last month and getting additional feedback from CLT workforce personnel on areas of required clarification. Outcomes form this meeting were specific requirements for some data exchange capability and additional design work on some of the lesser mature areas. Shadow engineering sessions for November are scheduled for the 16th and 17th. These sessions will be a bit lower key than previous months since NASA believes they have a sufficient amount of information from previous sessions and are still incorporating it into the software. There will be NASA engineers shadowing TMCs in both the TRACON and the tower during this same time. As always, NATCA representatives participating in these sessions are looking out for the best interests of the workforce to ensure that the ATD-2 system works in a manner that best suits controllers needs. COLLABORATIVE DECISION MAKING (CDM) Kyle Andrews (ORD) is the NATCA Representative to the Surface Concept Team (SCT). Mr. Andrews forwarded the information below for the membership. There were no face-to-face meetings in November, but the Airport Surface Efficiency Office gave information on the following activities. Tasking 66 "TBFM Prescheduling Test in MSP" is nearing conclusion with mixed results. The airports in the coverage area with flights to MSP had already started a program where ground delays of more than thirty minutes triggered automatic releases, with ZMP controllers then working out the spacing to MSP in the air. Because of this, significantly lower benefits were seen from the TBFM trial as compared to the DCA-LGA prescheduling test that took place last spring. Also, the MSP test created extra workload for the controllers, by increasing the number of missed windows and adding additional release calls. This highlights one of the difficulties that has
