Early Technology Transfer of ATD-2 Technologies
November 2, 2017

On October 16, 2017, the Federal Aviation Administration (FAA) NextGen office, the sponsoring organization for the Integrated Arrival/Departure/Surface (IADS) Research Transition Team (RTT), requested an early technology transfer of Airspace Technology Demonstration 2 (ATD-2) technologies. A technical interchange meeting was held on October 10, 2017, to discuss details of the early Tech Transfer of the IADS system for the FAA’s Limited-Trajectory Based Operations (L-TBO) Project. The L-TBO Team is interested in using NASA’s ATD-2 IADS system, particularly the Integrated Departure Arrival Capability (IDAC) to demonstrate a subset of the TBO-based operational improvement increments identified for the delivery into the National Airspace System (NAS) in 2025. Demonstration capabilities will be selected and integrated across all phases of flight to illustrate “closed loop” operations, as well as collaboration, information sharing, feedback, synchronization and negotiation. L-TBO will also connect the dots between previous demonstration efforts supported by NextGen at the Florida Test Bed (FTB) including Mini Global, Aircraft Access to System-Wide Information Management (SWIM), 4DT Datacomm, and Advanced Trajectory Modeling. The early Tech Transfer provides another application of the ATD-2 system, and the FAA L-TBO Team will continue to review progress and lessons learned with the NASA team. The FAA expressed appreciation for the work that the NASA ATD-2 Team has done so far, and looks forward to continued partnership to improve the National Airspace System. (POC: Jane Thipphavong)

Phase 1A Status Meeting
November 2, 2017

An Airspace Technology Demonstration 2 (ATD-2) Status Meeting was held on October 12, 2017 with field demo partners to assess progress since the ATD-2 Phase 1 Integrated Arrival/Departure/Surface (IADS) Baseline Demonstration began on September 29, 2017 at Charlotte Douglas International Airport (CLT). The Phase 1 Demo is being conducted as a series of micro-phases, each introducing additional capabilities to IADS system users. Phase 1A enables all data exchange features between the Federal Aviation Administration’s (FAA’s) Air Traffic Control Tower (ATCT) and the American Airlines (AAL) ramp as part of daily operations to be conducted via the ATD-2 system. Field Demo Partners from the National Air Traffic Controllers Association (NATCA), CLT Airport Ops, AAL, FAA Headquarters, and CLT ATCT participated in the Status Meeting. Topics discussed included perceptions since “Go Live,” the deployed software patches, features planned for the next software release, the next shadow session, and the feedback provided to date. Field demo partners have indicated that Phase 1A is progressing well, and provide ample feedback both verbally and via a formal feedback form. (POC: Shivanjli Sharma)

Virtual Training on ATD-2 New Features for American Airlines Ramp Managers
November 2, 2017

On October 23, 2017, the NASA Airspace Technology Demonstration 2 (ATD-2) Team conducted a virtual training session for American Airlines (AAL) Ramp Managers and the Ramp Managing Director on new features in the ATD-2 Ramp Management Tools. The Ramp Management Tools are part of the Integrated Arrival/Departure/Surface (IADS) system deployed at Charlotte Douglas International Airport (CLT), and are in daily operational use in the AAL Ramp Tower during the Phase 1 Field Demonstration. The Ramp Management tools consist of the Ramp Traffic Console (RTC) and Ramp Manager Traffic Console (RMTC). There are currently four RTCs and one RMTC deployed on the operational floor in the AAL CLT Ramp Tower. The new features include the ability to create a target for an existing flight, the ability to reposition flights on the display, and updates to the flight menus. The Ramp Managers indicated looking forward to using these new features in the updated software release on October 24, 2017. (POC: Lindsay Stevens)

Phase 1A Shadow Session

On October 25, 2017, Shadow Session 13 for the Airspace Technology Demonstration 2 (ATD-2) Phase 1 Field Demonstration (OSE1) was conducted in the NASA ATD-2 Lab (CLTlab) located at Charlotte Douglas International Airport (CLT). The ATD-2 Phase 1 Integrated Arrival/Departure/Surface (IADS) Baseline Demonstration began on September 29, 2017 and is conducted in a series of micro-phases. Phase 1A involves using the ATD-2 system for all data exchange features between the FAA Air Traffic Control Tower (ATCT) and the AAL ramp. Phase 1B will include the use of the ATD-2 system for electronic negotiation between CLT ATCT and Washington Air Route Traffic Control Center (ARTCC) for Call for Release (CFR) departure scheduling and is scheduled to begin on November 1. The objective of the shadow session was to review Phase 1A, demonstrate new features of the recent software release and discuss procedures for Phase 1B. Field demo partners from the National Air Traffic Controllers Association (NATCA), American Airlines (AAL), FAA Headquarters, Washington ARTCC, and CLT ATCT participated in the OSE1 session. The NASA team reviewed current feedback received, tech support resolutions, and planned improvements in the IADS system based on user feedback. Discussions provided valuable input on the progress of the Phase 1 Field Demonstration, and Field Demo Partners expressed their enthusiasm for Phase 1B. (POC: Shivanjli Sharma)

NASA Contributes to the FAA’s Terminal Flight Data Manager (TFDM) Build 2 System Requirements Review
November 2, 2017

On October 18-19, 2017, NASA Airspace Technology Demonstration 2 (ATD-2) team members provided field demonstration lessons learned in support of the Terminal Flight Data Manager (TFDM) kickoff of Build 2 requirements in a meeting hosted at the Federal Aviation Administration (FAA) headquarters in Washington, D.C. The initial TFDM Build focused on core electronic flight strip capabilities and data exchange, whereas Build 2 will deliver the decision support tools to help tower controllers better manage arrival and departure traffic at congested airports. NASA’s ongoing ATD-2 field demonstration at Charlotte Douglas International airport is evaluating several technologies relevant to TFDM Build 2. The meeting included key personnel from FAA TFDM program office, FAA surface office, the national NATCA representatives for TFDM and ATD-2, FAA’s ANG program office, the TFDM vendor (Leidos) and subcontractor (Saab Sensis). The meeting addressed the TFDM Build 2 System Specification Document requirements and resolved specific questions or ambiguities before the contractor engaged in the work. NASA explained the ATD-2 Integrated Arrival/Departure/Surface (IADS) implementation of some of the requirements, and gave examples to use as potential references during the Build 2 design. Some technology transfer items discussed include sources of predicted landing time data for arrivals that are used in the IADS algorithms. NASA is committed to effectively transferring the technology developed by ATD-2 to FAA and Industry, and is actively engaging with stakeholders to accomplish incremental transfers early and often.

Phase 1B Begins

On November 1, 2017, the Airspace Technology Demonstration 2 (ATD-2) Integrated Arrival/Departure/Surface (IADS) field demonstration at Charlotte Douglas International Airport (CLT) began Phase 1B operations. In this “micro-phase,” Federal Aviation Administration (FAA) Traffic Management Coordinators (TMCs) at the CLT Air Traffic Control Tower (ATCT) and Washington Air Route Traffic Control Center (ARTCC) will use the ATD-2 system to electronically negotiate takeoff times for Call for Release (a.k.a. Approval Request or APREQ) departures being scheduled into busy northeast corridor overhead traffic flows. The ATD-2 electronic negotiation feature builds on the Integrated Departure Arrival Capability (IDAC) in the FAA’s Time Based Flow Management (TBFM) system. In the ATD-2 implementation, the standard IDAC tower user interface is replaced by the ATD-2 IADS Surface Trajectory Based Operations (STBO) component, enabling Tower TMCs to perform IDAC-style scheduling for APREQ flights with their primary surface tool. Additionally, the ATD-2 implementation automatically delivers predicted takeoff times from the STBO surface tool to the Center tool, thereby improving CLT departure demand predictions used by the TBFM scheduling system. The ATD-2 IADS system also includes user interfaces at the CLT ramp tower providing ramp managers and controllers with information on negotiated APREQ release times and pushback advisories to meet APREQ times. This achievement represented 17 months of collaboration between the NASA ATD-2 team, multiple FAA organizations, and the TBFM contractor, to implement a secure and reliable network interface between the NASA ATD-2 IADS system at CLT and the operational FAA TBFM system at Washington ARTCC. The collaboration produced a new interface without requiring any code changes to the TBFM system, which will serve as a model for future FAA efforts to integrate TBFM with other decision support systems. The Phase 1B field demo plan calls for CLT ATCT and Washington ARTCC to initially use the ATD-2 electronic APREQ scheduling in a semi-automatic mode (i.e., requiring the ARTCC TMC to acknowledge a negotiated release time) supplemented with a phone call (i.e., same as manual APREQ scheduling). After an initial confidence-building period, the supplemental phone call will be dropped and the ATD-2 system will be routinely operated in semi-automatic mode. The eventual goal is to demonstrate sufficient APREQ compliance performance for the ATD-2 system to be operated in fully-automatic mode for APREQ scheduling. (POC: Shawn Engelland)
