ERAM replaces the 40-year-old HOST system currently used at the 20 Air Route Traffic Control Centers (ARTCC). ERAM, technology wise, is the most complex system of the Next Generation Air Transportation System (NextGen) and National Airspace System (NERAM replaces the 40-year-old HOST system currently used at the 20 Air Route Traffic Control Centers (ARTCC). ERAM, technology wise, is the most complex system of the Next Generation Air Transportation System (NextGen) and National Airspace System (NAS). ERAM assists the current en route paradigm to migrate from a ground-based system of air traffic control to a satellite-based system of air traffic management. ERAM contributes to the DOT Strategic Plan's Safety goal to reduce transportation related injuries and fatalities and the Economic Competitiveness goal of achieving maximum economic returns on transportation policies and investment outcomes. In the Next Generation Air Transportation System (NextGen) timeframe, demand for air transportation and other airspace services is expected to grow significantly from today's levels in terms of passenger volume, amount of cargo shipped, and overall number of flights. ERAM is committed to increasing capacity and improving efficiency within and providing for a safe NAS. ERAM provides a fully redundant system with no loss of service when either the primary computer fails or is not available during planned system maintenance. ERAM also increases the number of flight plans that can be stored; provides flexibility in airspace configuration; and extends radar coverage in all ARTCCs by increasing the number of radar feeds. For pilots, ERAM increases flexible routing around congestion, weather, and other restrictions which supports improved safety for the NAS. For controllers, ERAM provides a user-friendly interface with customizable displays. Controllers will benefit from reduced workloads along with NAS wide data sharing between ARTCCs. The ERAM is composed of the Enhanced Backup Surveillance (EBUS) system; technical refresh of the Radar Position Display Processor; and En Route Information Display (ERIDS) system (electronic tool that distributes information to controllers to improve their productivity and efficiency) and ERAM Release 1, 2 and 3. EBUS and ERIDS are fully operational at all sites. The ERAM system (hardware and initial software) has been installed at all 20 ARTCCs. ERAM Release 2 was used as the system baseline for sites to achieve Initial Operational Capability (IOC). Key customers/stakeholders are: air traffic controllers, American flying public, air carriers of passengers/cargo, Department of Defense (military aviation), and first responders supporting the Homeland Security mission.

Sixteen (16) of twenty (20) sites have achieved Initial Operational Capability (IOC) including 7 In FY13. Eleven (11) of the sixteen (16) have reachedSixteen (16) of twenty (20) sites have achieved Initial Operational Capability (IOC) including 7 In FY13. Eleven (11) of the sixteen (16) have reached continuous operations including 5 in FY13. 9 of the 11 have declared Operational Readiness Date (ORD); including 7 in FY13, as Houston (ZHU) achieved ORD April 30, 2013 and Kansas City (ZKC) achieved ORD April 4, 2013. Between 12/19/2011 and 4/15/2013, ERAM has accumulated approximately 69,625 hours of operational run time across all ERAM sites. However, due to the current sequester, further progress for achieving the ERAM August 2014 milestone is at risk. Full impacts of sequestration on achieving the remaining operational targets / milestones are being evaluated. More..
