ATAC TestBed Transition Model and Tradeoff Study
July 15, 2020

Proposed Support Structure Functional Areas and Organization

ATAC completed an analysis on the TestBed Transition Model Trade-off and provided a final briefing to line and project managers at NASA Ames and Langley Research Centers, on July 10, 2020. The analysis looked at three support models for future TestBed operations: entirely managed by NASA, completely external to NASA, and a hybrid of the two. The briefing focused on an example hybrid case, assuming certain percentages of resources provided by each of NASA and external parties. A spreadsheet for calculating an estimate of the required resources can be customized to allow NASA to perform further analysis.

NASA ATD-2 Phase 3 Stormy 2020 Training Videos and Presentations
July 8, 2020

The NASA Airspace Technology Demonstration 2 (ATD-2) team has adjusted its training practices in response to the COVID-19 working conditions and visitor restrictions, in place since March 2020. Originally, the team was scheduled to provide face-to-face, hands-on training at each of the seven field demonstration sites in the North Texas area which included both flight operator and air traffic control facilities. To continue the training mission under remote working conditions, the ATD-2 team produced training videos and slide presentations with embedded audio explanations for each training site. The training content was reorganized into smaller segments that were designed to explain specific functions of the ATD-2 system, and were tailored to the specific user group. For instance, the flight operator videos were made with examples related to that individual airline to further enhance the learning experiences with real world use cases. The videos can be utilized both as an on the spot training resource by active, operational personnel or in a more formal training environment. This training material delivery approach has the added benefit of allowing later updates with new training resources or other modifications as user capability changes. Feedback from the field users has been very positive regarding the web site training materials.

UTM Project and Smart Mobility at Ames team returns to Center for Flight Operations
July 8, 2020

A series of small Unmanned Aircraft Systems (UAS) operations were conducted by the UAS Traffic Management (UTM) project and Smart Mobility at Ames teams, at the Moffett Field (CA) airport N248 ramp area, June 29-30, 2020. The purpose of these operations was to check the feasibility of several flight profiles prepared for testing the Time-Based Conformance Monitoring (TBCM) concept, an advanced UAS Service Supplier (USS) feature designed to enable the continuation of planned UAS missions in a communications-challenged area. Due to COVID-19, a return-to-work plan that contained strict safety guidelines, such as social distancing and use of Personal Protective Equipment (PPE) was developed and approved by the Center. The test participants followed the guidelines, safely completing the two-day operation with successful data collection. The flight profile feasibility analysis will be performed with the collected data, and the team is planning to return to the test range for additional data collection to further test the TBCM concept.

Completion of Tailored Arrival Manager (TAM) 5B Testing with FAA and Boeing

NASA collaborated with the Federal Aviation Administration (FAA) and Boeing in a simulation known as the Tailored Arrival Manager (TAM) 5B, on May 27, 2020. The simulation, part of preparations for the eco Demonstrator (ecoD) flight demonstration involving NASA’s Tailored Arrival Manager, was successfully completed with only Boeing having physical access to laboratory facilities due to COVID-19 restrictions. The NASA team remotely operated systems in the Aviation Systems Division’s TestBed lab to generate TAM solutions using periodic input data from a B787 simulator and Flight Management System (FMS) in Boeing’s Integrated Aircraft Systems Laboratory (IASL). With the FAA unable to access their data communications laboratory in New Jersey, TAM trajectory solutions were relayed manually to the Boeing flight deck.

TAM-5B marked the first opportunity to integrate with real-world avionics representing a B787, which was recently confirmed by Boeing as the aircraft type for the ecoD 2020 flight. Key accomplishments of the test included the acquisition of 1 Hz track data representing Automatic Dependent Surveillance-Broadcast (ADS-B) and the verification of coordinate transformations performed by the FAA in translating TAM solutions into Controller-Pilot Datalink Communications (CPDLC) messages.

ADS-B-like data from the B787 relied on Boeing sending data to the FAA using a simulation data exchange standard known as Test and Training and Enabling Architecture (TENA). Upon receiving TENA data from Boeing, the FAA’s Target Generation Facility (TGF) formatted the data into track messages and sent them to TAM via TestBed. This data interface with TestBed can conceivably be used to acquire ADS-B data from any live flight in the National Airspace System (NAS). The availability ADS-B data for ecoD flights – the first expected in August 2020 – will provide an additional source of aircraft position and velocity in the event of data contingencies.

ATM-X TestBed Demo for FAA NextGen Office
June 4, 2020

The NASA Air Traffic Management Exploration (ATM-X) project conducted an ATM-X TestBed online demo for representatives from the Federal Aviation Administration (FAA) and its support organization, Concepts Beyond, as requested by Mr. Matt Modderno from the NextGen office. The demonstration, on May 19, 2020, included a discussion around an example use case from a recent ecoDemonstrator test to show how TestBed is used along with its simulation tools. The demo includes the Software Development Kit’s adapter template code generation Wizard. An adapter is an interface code between TestBed and a user’s application. NASA also provided TestBed’s documentation, including its Interface Control Document, to the FAA.
