ATD-2 Software Release with Significant New Capabilities
January 26, 2017

On January 20, 2017, the ATD-2 Software Development Team delivered version 2.1 of the Integrated Arrival/Departure/Surface (IADS) system. ATD-2 has followed an agile requirements definition and software development process wherein field demo partners are exposed to the IADS system in live-data shadow evaluation sessions and provide feedback on system requirements. The IADS v2.1 release implements a large percentage of the requirements identified during five shadow sessions conducted from July - November 2016. The last major release was in mid-October. Key areas of development included: refinement of a data fuser system to handle the vast array of input data feeds, new user interface components to support air traffic control tower (ATCT) and Ramp Tower collaboration, significant maturation of the tactical scheduling and metering functions, re-engineering of the Ramp Traffic Console user interface for better supportability, re-design of ATCT controller interface for usability, enhancements to the departure scheduling interface between IADS and the FAA's Time Based Flow Management (TBFM) system, and adaptation enhancements to reflect Charlotte Douglas International Airport (CLT) operations. The IADS v2.1 release will be used in Shadow Session #7 January 24-26, 2017 at the ATD-2 lab in CLT. During this shadow session, NASA researchers will review the latest capabilities with field demo partners and use their feedback to further refine the IADS system in advance of an upcoming human-in-the-loop (HITL) simulation (March 7-9, 2017) and the ATD-2 Phase 1 field demonstration requirements freeze on March 29, 2017.

On January 19, 2017, the Airspace Technology Demonstration-2 (ATD-2) Experiment Team successfully performed a third baseline Human-In-The-Loop (HITL) test integrating the airspace and surface traffic simulators—Multi-Aircraft Control System (MACS) and the Air Traffic Generator (ATG). This test was conducted at FutureFlight Central (FFC) and the Airspace Operations Laboratory (AOL) at NASA Ames Research Center. This simulation environment supported the integration of several ATD-2 components, including the Surface Trajectory-Based Operation (STBO) system, its user interfaces, and its connection with Time-Based Flow Management (TBFM). The test focused on evaluating the tactical departure scheduler and Call For Release procedure between Charlotte Tower and Washington Center. The scenario simulated 580 flights that included both arrivals and departures, and overhead traffic. The operation was tested at full levels of traffic and included turnaround flights in the South Flow configuration. This HITL test also included the 360-degree simulation of the airline ramp operations along with the smaller-scale virtual Air Traffic Control Tower (ATCT). Future test scenarios will feature different runway configurations, and continue testing the integration of surface metering and tactical departure scheduling. This third test prepares for a HITL shakedown with retired controller participants scheduled in mid-February. The HITL data collection is scheduled March 7-9, 2017, where Federal Aviation Administration (FAA) and air carrier participants will evaluate the ATD-2 system and operational procedures expected for the Phase 1 Field Demonstration.
