ATM-X DIP Sub-Project Completes Initial Design Elements for CDDR
October 19, 2021

On September 30, 2021, the Air Traffic Management Exploration (ATM-X) Project’s Digital Information Platform (DIP) Sub-Project completed several technical design elements of the Collaborative Digital Departure Reroute (CDDR) service. The service will be evaluated and validated beginning in FY22, during the first demonstration in DIP’s Sustainable Aviation Demonstration series, at the NASA/FAA North Texas Research Station (NTX). The CDDR service has been designed to utilize a collection of new machine learning (ML) based services to provide near real-time predictions for airport surface models. The ATD-2 approach provides these predictions as a single service and are now being redesigned and decoupled in the DIP Sub-Project to work as independent services, a key DIP objective to enable greater use of ML-based services and to enable these modular services to serve as building blocks for more complex services in a transformed National Airspace System (NAS). This gives DIP a jump start in offering high-value reusable services for the community to leverage.

DIP/DRF Conducts TIM
October 19, 2021

On October 6, 2021, the ATM-X Project’s DIP Sub-Project and the Data & Reasoning Fabric (DRF) team from the TACP/Convergent Aeronautics Solutions Project gathered for the first in a series of virtual Technical Interchange Meetings (TIMs) to share approaches of common capabilities identified in both projects, and to identify potential areas for collaboration or integration. Each project offers a platform or framework to connect services, and there are some common basic features with similar requirements, but due to different community needs and objectives, there are also differentiation features. The first TIM covered approaches to common functionalities in terms of deployment and cloud usage. Follow-on TIMs will cover additional common functionalities such as registry and catalog of services, as well as security for authentication and authorization.

FAA TIM on FIXM/FLXM and FF-ICE/CSS-FD
October 19, 2021

On October 13–14, 2021, representatives from the ATM-X Project’s DIP Sub-Project Team attended the FAA’s in-person TIM on global standards for Flight and Flow Information Exchange in Washington, D.C. The FAA briefed the standards and messaging templates developed under the Flight Information Exchange Model (FIXM) and the early iterations of Flow Information Exchange Model (FLXM), developed through international collaboration under the International Civil Aviation Organization (ICAO). As DIP develops standards for services sharing information, the platform should maintain an approach complementary to standards developed by the FAA and ICAO. The DIP team presented an overview of Fuser, a service for integrating and reconciling data from multiple sources. The FAA indicated interest in a deeper understanding of Fuser, with consideration for a technology transfer of Fuser through the Digital Mesh Technology and Application (DMTA) Research Transition Team (RTT). Additionally, the FAA provided more insight to the Flight and Flow Information for a Collaborative Environment (FF-ICE) concept, and the United States’ instantiation of FF-ICE known as Common Support Services – Flight Data (CSS-FD). The FAA invited NASA to attend their tabletop sessions to better understand the capabilities of the Multi-Regional Trajectory Based Operations (MR-TBO) concept and share the scope of the related lab activities.
