. Traffic Flow Management System Benefits Flexibility for Future Growth: TFMS provides a modern software architecture to meet future growth and support complex capabilities. Enables the FAA to respond more quickly to changes in traffic management strategies Continuous growth in the use of the NAS necessitates scalability, improved data interfaces, improved security features and business process optimization For more information contact: Kathy Koerner, Director TFMS Traffic Flow Management Modernization Under the Traffic Flow Management-Modernization (TFM-M) contract, CSC is building the Traffic Flow Management System (TFMS) which will replace the current Enhanced Traffic Management System (ETMS) initially developed in the 1980s. ETMS is the principle component of the TFM infrastructure used by the FAA and NAS stakeholders to predict demand, identify constraints, mitigate delays and maintain common situation awareness. ETMS is used by the Air Traffic Control System Command Center (ATCSCC), Air Route Traffic Control Centers (ARTCCs), Terminal Radar Approach Control (TRACON) field sites, Towers, FAA field offices, as well as other government and military agencies, airline operation centers, the general aviation community and international partners. TFMS is based on an open architecture platform supporting the integration of TFM subsystems, facilitating integration with other domains, and supporting responses to new initiatives. In addition to improving development bandwidth, TFMS establishes a platform that is sustainable and scalable for the next decade and beyond. TFMS Service Oriented Architecture

Advanced Technology System Integration With experience in approaches developed for commercial use and proven in the Federal market, CSC is capitalizing on advances in system integration technology for TFMS. TFMS employs a Service Oriented Architecture (SOA) based on systems technologies that include business process management, portals, XML-based messaging, improved business rules execution, a relational database, and reporting tools. The modernized TFMS infrastructure will adhere to open industry-driven standards such as the Java 2-Enterprise Edition (J2EE) suite and eXtensible Markup Language (XML). Modular services minimize the impact of changes to the NAS by avoidance of internal function tangling. TFMS accomplishes this by isolating interfaces from processing components (including system-to- system interfaces and human-computer interfaces), isolating data management from processing, and modularizing processing in subsystems. Leverage Lessons Learned The Traffic Flow Management System builds upon lessons learned from ETMS and provides a modern, state of the art technology for a scalable, flexible, and open infrastructure to support the evolving and expanding NAS. New capabilities to be addressed once the modernization of infrastructure is complete include improved airspace management via more precise application of initiatives, augmented data interfaces with NAS systems to improve predictions, improved assessment capabilities by allowing reroute modeling which includes user preferences, and improved performance measures which will provide feedback for overall process improvement. Modernized TFMS components will support all of these initiatives, and set the stage for the future. Experience. Results. TFMS provides a modern software architecture to meet future growth and support complex capabilities not possible with the legacy system, e.g., modeling the effects of candidate Traffic Management Initiatives (TMI) on the National Air Space (NAS) to help ensure the selection and execution of the most efficient and equitable alternative (see FAA Flight Plan Objective 2: Increase reliability and on-time performance of scheduled carriers). TFMS enables the FAA to respond more quickly to changes in traffic management strategies. For example, many operational procedures are based on existing patterns of airspace use. With the rapidly changing approaches to air traffic cost improvement being developed by the airlines (regional jets, etc.), The Total Flight Planning Package: Direct User Access Terminal Service (DUATS) Innovation and Results from a Trusted Partner the ability to rapidly adapt the traffic analysis and flow management has become critical. Representing these operations with computer-orchestrated services facilitates controlled incremental change. Continuous growth in the use of the NAS necessitates scalability, improved data interfaces, improved security features and business process optimization. TFMS will support and encourage enhancements and improvements, utilizing a scalable, state- of-the-art service based architecture to allow for optimized change and growth. TFMS will also support research and technology prototyping, facilitated by the modernized infrastructure.
