Technical Center White Papers

By Nancy Sheffield

_____________________________________________________________________

This article is the first in a series of three that will highlight the many individuals at the Technical Center who have shared their thoughts, creative thinking and technical expertise with the world by becoming published. Part one is highlighting ACB-330, Conflict Probe Assessment Team (CPAT). In an interview with Mike Paglione, CPAT lead, he indicated that having a white paper accepted and being chosen to present at conferences is a significant goal that his team hopes to achieve. As you read this article, you will see ACB-330’s untiring efforts as a team in the world of publications.

Under the Simulation and Analysis Group (ACB-330), the CPAT is a small team of engineers, computer scientists, and air traffic subject matter specialists who are responsible for performing technical analyses and building traffic scenarios for the Free Flight Program Office. CPAT was organized in 1996 to perform an independent assessment of the User Request Evaluation Tool (URET) algorithms. Since then, the team has conducted projects on both the URET and Center TRACON Automation System (CTAS) programs. 

For example, the team supported the deployment of the URET Core Capability Limited Deployment (CCLD) system by developing the input traffic scenarios and the accuracy specifications for the URET CCLD Formal Accuracy Test. Currently, CPAT is providing government furnished test data for new URETdeployment sites and supporting the development of an operations concept for the CTAS tool, Direct-To.  The team is also active in producing technical publications. Over the years, the team has had papers published in or presented at national conferences. These include:

• Air Traffic Control Association’s Air Traffic Quarterly,

• USA/EUROPE Air Traffic Management R&D Seminar,

• American Institute of Aeronautics and Astronautics (AIAA) Guidance, Navigation, and Control Conference,

• Digital Avionics Systems Conference (DASC)

• Air Traffic Control Association’s Annual Conference Proceedings.

The team has also authored several FAA Technical notes and reports. A sample of CPAT’s most recent publications includes:

• “Time Shifting Air Traffic Data for Quantitative Evaluation of a Conflict probe,” Mike M. Paglione, Robert D. Oaks, J. Scott Summerill, submitted to the American Institute of Aeronautics and Astronautics (AIAA) Guidance, Navigation, and Control Conference, Austin, TX; August 2003.

• “Advances in the Federal Aviation Administration Testing of the User Request Evaluation Tool Using an Off the Shelf Animation Package,” M. M. Paglione, S. K. Singhal, R. D. Oaks, S. Liu, Air Traffic Control Association (ATCA) 47th Annual Conference Proceedings; November 2002.

• “Generation of Realistic Air Traffic Scenarios Using a Genetic Algorithm,” Robert D. Oaks, Mike Paglione, 21^st Digital Avionics Systems Conference (DASC), October 28-31, 2002; Irvine, CA.

• “A Generic Sampling Technique For Measuring Aircraft Trajectory Prediction Accuracy,” Mary Lee Cale, Shurong Liu, Robert D. Oaks, Mike Paglione, Dr. Hollis F. Ryan, Scott Summerill, 4th USA/EUROPE Air Traffic Management R&D Seminar; December 3-7, 2001.
