Tool Delivered for Creating Future Air Traffic Demand Data: On Thursday, February 8th, 2007 Sensis Corporation delivered to NASA their SBIR Phase II final briefing and software for AvDemand, a tool for generating and analyzing future air traffic demand sets. AvDemand has been used to create future traffic demand sets in support of the Preliminary System-wide Concept Assessment, the development of Dr. Erzberger's automated conflict resolution, and Mr. McNally's ARMD seminar on separation assurance. In addition, AvDemand will help researchers satisfy NGATS ATM project milestones by continuing to create realistic representations of future air traffic demand sets with features that consider passenger weighting, user class, tail connectivity, fleet mix, and business case shifts.

FACET/ACES Integration Tool: The Aerospace Operations Modeling (AFM) and Automation Concepts Research (AFC) branches have an ongoing contract with Optimal Synthesis Inc. to integrate FACET and ACES into a combined tool. In this tool, ACES will generate targets, and FACET will generate strategic traffic flow management plans. On Friday March 23rd, Optimal Synthesis will deliver version 1.0 of the software, including documentation. This tool will be used to create and assess traffic flow management concepts and show how they integrate with the other concepts being developed under the NGATS ATM Airspace Project.

Surface Operations Data Analysis Tool Upgrade Released to NASA Researchers: The NGATS ATM - Airportal and NGATS ATM - Airspace projects have both identified a requirement for software tools to collect, organize and analyze surface and terminal operations data. NASA Ames' Aviation Systems Division has begun leveraging an SBIR effort by Mosaic ATM, Inc. to develop the Surface Operations Data Analysis and Adaptation (SODAA) tool. The SODAA tool couples a sophisticated database design with a data management and visualization module. SODAA ingests surface and terminal surveillance data from various sources, computes and stores a wide array of derived data elements and provides the researcher with tools to manage, query, mine and visualize the raw and derived data elements.

The initial SODAA release (delivered on 12/13/2006) featured the ability to compute more than 30 derived data elements from raw surface surveillance data. Both the raw and derived data are then stored in the SODAA database and accessed via queries executed from the visualization and analysis tool. The 3/9/2007 release, added the ability to process about 80 Surface Management System (SMS) data elements. With this much-anticipated enhancement, NASA researchers can now run database queries against a combination of raw surface surveillance data, SODAA derived elements and SMS output data. Researcher feedback will continue to be instrumental in guiding SODAA development during the remainder of the Phase II SBIR effort which ends in December 2007.

Automatic Recognition of Runway Configuration: An initial study of automated runway configuration recognition has produced a method that is ready for testing with operational data (e.g., ASDE-X). The automatic recognition capability enables the determination of runway configuration without manual entry (via controller input), and helps with the determination of airport capacity and runway usage, as well as provide distributions of inter-operation times. This data can contribute to planning surface and terminal area traffic management.

Technology Partnerships: A NASA Case Study: Dr. Banavar Sridhar was a keynote speaker at the Federal Aviation Administration (FAA) Information Technology/ Information Systems Security Conference in Dallas, TX on March 15, 2007. The conference was sponsored by the Chief Information Officer of the FAA. Dr. Sridhar's talk "Technology Partnerships: A NASA Case Study" described the various steps in the successful transfer of NASA developed technology through the use of Space Act agreements and Licensing. The technology transfer steps were described using the Future ATM (Air Traffic Management) Concepts Evaluation Tool (FACET), an environment for modeling and evaluating system-wide airspace operations over the United States. NASA has worked with the FAA, airlines, industry and universities to transfer this technology to different classes of users. This talk describes the lessons learned in technology transfer through an example. Although implementation issues are presented here with respect to FACET, the comments apply generally to the development and transfer of NASA technology.

Received notice of technical paper accepted for publication in the ATC Quarterly Journal, 3/13/07. The paper will probably appear in the issue for the next quarter of 2007: McNally, D., Gong, C., "Concept and Laboratory Analysis of Trajectory-Based Automation for Separation Assurance"
