Enhanced Traffic Management System (ETMS)

Updated:11:00 AM May 03, 2012

The Federal Aviation Administration (FAA) uses the Enhanced Traffic Management System (ETMS) at the Air Traffic Control System Command Center (ATCSCC), the Air Route Traffic Control Centers (ARTCCs), and major Terminal Radar Approach Control (TRACON) facilities to manage the flow of air traffic within the National Airspace System (NAS).  Other organizations (e.g., the airlines, Department of Defense, NASA, and international sites) also have access to the ETMS software and/or data.  The ETMS provides Traffic Management Specialists with tools such as Traffic Situation Display, and traffic counts for airspace sectors, airports, and fixes.

We support the development and implementation of requirements in the ETMS.  We work with the Traffic Flow and Enterprise Management Integrated Product Team (AUA-700), software developers at the Volpe National Transportation Center, and various user teams to specify functional and interface requirements for new ETMS tools.  Recently we have worked on capabilities such as creating flow constrained areas, identifying the aircraft that will be affected by those areas, and specifying reroutes to move traffic around the constraints.  In addition to working on new ETMS functions, we review existing capabilities and identify enhancements that will make the system more usable.

We are currently working with a multidisciplinary team to define requirements for an en route modeling function.  This capability will allow a Specialist to evaluate the impact of a reroute prior to implementation.  To ensure that the design of the function will meet the needs of the specialists in the field, we visited the Air Traffic System Command Center (ATCSCC), the facility primarily responsible for issuing reroutes.  We analyzed the work flow and information requirements of evaluating reroute options and the impact they will have on the National Airspace System.
