Third Dynamic Routes for Arrivals in Weather (DRAW) simulation completed
May 10, 2018

DRAW Simulation

The third in a series of planned Human-in-the-Loop (HITL) studies of the Dynamic Routes for Arrivals in Weather (DRAW) tool was conducted from April 23-May 4, 2018, in NASA Ames Research Center’s Air Traffic Control (ATC) Simulation Laboratory. DRAW HITL#3 investigated the use of DRAW in an arrival metering context within the Atlanta Air Route Traffic Control Center (ZTL ARTCC) airspace to solicit feedback towards refinement of the DRAW concept of operations by expanding assessment in a new airspace (ZTL ARTCC) that presents a significantly different arrival metering operation than previous studies using Fort Worth ARTCC. A secondary objective of DRAW HITL#3 was to expand knowledge of DRAW use in an environment approximating ‘extended metering’ operations requiring rerouting of flights with ‘frozen’ scheduled times of arrival (STAs). Study participants included 4 recently-retired Traffic Management Coordinators (TMCs) from ZTL and 7 recently-retired Sector Controllers (2 from ZTL, 5 from Oakland ARTCC). The four TMCs were each presented with four weather-impacted arrival traffic scenarios (16 total runs). DRAW provided TMCs with reroute advisories and schedule impact/delay information. TMCs used the DRAW trial planning capability to evaluate candidate reroutes for weather avoidance, assess their schedule delay impact, and amend flight routes as necessary to maintain effective arrival metering. Questionnaires were administered to both TMC and Sector Controller participants and data were collected to analyze arrival metering and DRAW performance. The primary objective of DRAW HITL#3 was to TMCs using DRAW in ZTL airspace routinely assessed reroute advisories for flights with frozen STAs and managed the arrival schedule as necessary, providing valuable feedback toward DRAW use in operations that will include extended metering and coupled scheduling.

UAS in the NAS project supports AUVSI XPONENTIAL 2018
May 10, 2018

UAS in the NAS AUVSI booth

Aviation Systems Division staff in the Unmanned Aircraft Systems Integration in the National Airspace System (UAS in the NAS) project hosted a booth at the Association of Unmanned Vehicle Systems International (AUVSI)’s XPONENTIAL conference, May 1-3, 2018, in Denver, Colorado. The NASA team exhibited the Vigilant Spirit Control Station to demonstrate the display of Detect-and-Avoid system alerting and guidance, using sample conflict scenarios for UAS and manned intruders. The event was attended by approximately 9,000 visitors. (POC: Gilbert Wu)

ATD-3 Participation in Collaborative Decision-Making (CDM) Spring Meeting
May 10, 2018

Dr. Kapil Sheth, Airspace Technology Demonstrations (ATD-3) subproject lead, attended the CDM Spring Meeting April 30-May 2 in Memphis, Tennessee. The meeting was held at the FedEx Institute of Technology on the campus of the University of Memphis. Dr. Sheth attended meetings with the Flow Evaluation Team (FET), PERTI (Plan, Execute, Review, Train, and Improve) Engagement Team (PET), and Surface CDM Team (SCT). FedEx Managing Director Mr. Dan Allen, and the CDM Steering Group leadership welcomed the attendees at the General Session. Mr. Lorne Cass, Manager of the American Airlines (AAL) Integrated Operations Center mentioned the successful partnership between NASA and American Airlines. Ms. Jennifer Ross of the Future Concepts Team (FCT) acknowledged Dr. Sheth’s longstanding contribution as a subject-matter expert on the FCT. The Federal Aviation Administration’s (FAA’s) Mr. Walter Abilla and Mr. Omar Baradi presented on the state of the 3Ts, namely, Terminal Flight Data Manager (TFDM), Time Based Flow Management (TBFM), and Traffic Flow Management System (TFMS). The sub-teams will continue work on their tasking and look forward to continued NASA involvement. (POC: Kapil Sheth)

NASA and American Airlines Host ATD-2 Technical Interchange Meeting with Flight Operators
May 10, 2018

NASA-American Airlines Technical Interchange

On April 17, 2018, NASA and American Airlines hosted air traffic management (ATM) experts from Delta Air Lines, JetBlue Airways, and Southwest Airlines for a technical interchange meeting at Charlotte Douglas International Airport (CLT). NASA provided an orientation briefing and hosted the visitors in observations of the Airspace Technology Demonstration 2 (ATD-2) Integrated Arrival/Departure/Surface (IADS) system being used for surface departure metering in the American Airlines Control Center (a.k.a. Ramp Tower) at CLT. The visitors observed FAA traffic management coordinators using the ATD-2 IADS system from the Air Traffic Control Tower and Terminal RADAR Approach Control (TRACON) facility. NASA and the airline ATM participants also convened for an in-depth technical interchange about the ATD-2 Field Demonstration. Key topics of discussion included the ongoing collaboration between NASA and the FAA to fully leverage ATD-2 research results for the benefit of the FAA’s Terminal Flight Data Manager (TFDM) program; investments that flight operators will need to make in preparation for TFDM deployment; and what NASA can do to more effectively transfer ATD-2 technology and findings to flight operators, airport operators, and the vendors that support them. American Airlines is serving as the “lead carrier” for the ATD-2 Field Demonstration, and this technical interchange meeting was one of several engagement opportunities for other flight operators to learn from their experience.

NASA Provides ATD-2 Familiarization for American Airlines Managers
May 10, 2018

Familiarization for American Airlines managers

On April 3-4, 2018, NASA provided Airspace Technology Demonstration 2 (ATD-2) familiarization for American Airlines’ Control Center Harmonization (CCH) team during their meeting at Charlotte Douglas International Airport (CLT). American Airlines is serving as the “lead carrier” for the ATD-2 Field Demonstration under a Non-reimbursable Space Act Agreement (NRSAA) and used this opportunity to familiarize more of the American management team with ATD-2 and the IADS system in use at CLT. The CCH team consists of managers and technical personnel from the Integrated Operations Center (IOC) and Control Centers (a.k.a. ramp towers) at each of American Airlines’ major hubs. The familiarization session included a review of the origins of the NASA/FAA collaboration on ATD-2 to demonstrate Surface Collaborative Decision Making (Surface CDM) departure metering as part of a holistic Integrated Arrival/Departure/Surface (IADS) system; an orientation to the ATD-2 IADS system and observations of the system being used in the American Airlines Control Center, the Air Traffic Control Tower, and the Terminal RADAR Approach Control (TRACON) facility; and briefings on field demo status and future plans, methodologies for operational data collection and analysis, and operational impact assessments. The CCH team was interested and engaged throughout the discussion and exchanged ideas on how to leverage the ATD-2 experience to prepare for FAA deployment of the Terminal Flight Data Manager (TFDM) capability.
