En Route Automation Modernization (ERAM)

A computer system used at FAA high-altitude en route centers, considered the backbone of the nation’s airspace system. it processes flight radar data, provides communications and generates display date to air traffic controllers. ERAM has increased flexibility in routing around congestion, weather and other airspace restrictions. Automatic flight coordination increases efficiency and capacity. The current system, called the Host, is being replaced by ERAM.
