Operational Risk Mitigation Simulation for Terminal Sequencing and Spacing (TSS)
January 30, 2015

From January 20-23, 2015, about twenty subjects took part in the first Operational Integration Assessment (OIA) Risk Mitigation (ORM-1) simulation. This series of four simulations is scheduled for the first quarter of this calendar year, each with the objective of reducing a specific risk for the OIA. Three of the ORM simulations will be performed at Ames Research Center, and one at the FAA's William J. Hughes Technical Center (WJHTC) in Atlantic City, NJ. The objective of ORM-1 was to validate the chart change update (CCU) that is required for the OIA, and to test out NASA's implementation of flexible scheduling in the NASA-modified Time-Based Flow Management (TBFM) v4.2.0. ORM-1 leveraged heavily the preliminary CCU update to TBFM and the Multi-aircraft Control System (MACS) performed by the Airspace Operations Laboratory (AOL). Raytheon performed the CCU update for the Standard Terminal Arrival Replacement System (STARS), including updating the video maps. Fourteen simulation runs were conducted over the course of 3 1/2 days. Testing also included off-nominal events with an emphasis on missed approaches. Refinements were made to various routes, adaptation, and software. Questionnaires were administered for the last twelve simulation runs. Observations in the laboratory indicated that the objectives of ORM-1 were met; however, more detailed analysis is underway. The simulation will transfer the new CCU release to the WJHTC today, where their engineers will update their various platforms to this CCU. ORM-2 occurred January 27-29, 2015 at Ames with the objective of training three active traffic managers on their roles and responsibilities during the OIA, planned for May 2015.

Spot and Runway Departure Advisor (SARDA) Operational Field Test Planning Meeting
January 30, 2015

Division managers and researchers supporting NASA's airport surface research effort, as well as planning team members from the Airspace Technology Demonstration-2 (ATD-2) planning team met in Fort Worth, TX, January 20-21, 2015 with American Airlines (AA) staff representing their information technology department and the AA Managing Director of Operations Planning and Performance and the Director of the Charlotte-Douglas International Airport (CLT, Charlotte, NC) Ramp Tower Operations. The purpose of the meeting was to discuss the upcoming plans for a field test of the Spot and Runway Departure Advisor (SARDA) technology at AA's CLT Ramp Tower. The teams discussed scheduling around AA's operational considerations, including preferred seasonal weather conditions, and avoiding constraints due to holidays, staffing, and the merger of operational systems between AA and US Airways. Requirements for networking, physical space, and technical questions regarding data request elements, features and architecture were also discussed. NASA provided updates on the findings from the human-in-the-loop simulation experiments performed at Ames Research Center in the past six months. The teams have additional information to gather from both sides in order to converge on an acceptable testing matrix and schedule. (POC: Mirna Johnson)

Tactical Departure Scheduling-Terminal (TDS-T) Workshop

On January 22, 2015, NASA's Tactical Departure Scheduling – Terminal (TDS-T) team hosted FAA subject matter experts for a workshop at the North Texas Research Station (NTX) in Fort Worth, Texas. The TDS-T research activity addresses the challenge of simultaneously satisfying national, regional, and local departure constraints while accommodating traffic from both well-equipped and less-equipped airports. During this workshop, traffic management supervisors and front-line managers from Dallas/Fort Worth (DFW) Terminal Radar Approach Control (TRACON) and the air traffic control towers at DFW and Dallas Love airports interacted with the TDS-T prototype decision support tool in the NTX laboratory. The TDS-T prototype tool ran in shadow mode with live data feeds and prototype user interfaces were configured to represent different terminal departure control environments: Center traffic management unit (TMU), TRACON TMU, large airport Tower, and small airport Tower. The FAA subject matter experts provided feedback on the TDS-T concept and the prototype tool; the feedback will be used to further refine the concept and technology. Members of NASA's Airspace Technology Demonstration #2 (ATD-2) formulation team observed the workshop and participated in ATD-2 concept definition discussions while at NTX. The ATD-2 formulation team is incorporating TDS-T research findings in the ATD-2 metroplex departure scheduling concept. (POC: Shawn Engelland)
