The En Route Automation Modernization (ERAM) system architecture replaces the En Route Host computer system and its backup. ERAM provides all of today's functionality and:[citation needed]
- Adds new capabilities needed to support the evolution of US National Airspace System.
- Improves information security and streamlines traffic flow at US international borders.
- Processes flight radar data.
- Provides communications support.
- Generates display data to air traffic controllers.
- The display system provides real-time electronic aeronautical information and efficient data management.
- Provides a fully functional backup system, precluding the need to restrict operations in the event of a primary failure.
- The backup system provides the National Transportation Safety Board-recommended safety alerts, altitude warnings and conflict alerts.
- Improves surveillance by using a greater number and variety of surveillance sources.
- Detects and alerts air traffic controllers when aircraft are flying too close together for both safety and long term planning.
- ERAM simultaneously supports many operating modes and complex airspace configurations, driven by thousands of users who want to use the airspace differently.
- Allows more radars and flights than the old Host Computer System which ERAM replaces.
The open system architecture enables the use of future capabilities to efficiently handle traffic growth, and ensure a more stable and supportable system.
