ERAM (En Route Automation Modernization) is an FAA program designed to "allow faster processing of route requests and in flight route changes".
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:
- 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.
ImplementationThe FAA will deploy ERAM at 20 Air Route Traffic Control Centers, the Williams J. Hughes Technical Center, and the FAA Academy.
Step 1: 2006 Replace the current En Route computer backup system with Enhanced Backup Surveillance.
Step 2: 2007 Provide controllers real-time electronic access to weather data, aeronautical data, air traffic control procedures documents, Notices to Airmen, pilot reports, and other information with the En Route Information Display System.
Step 3: 2009 Replace the current En Route Host computer air traffic control with a fully redundant, state of the art system that enables new capabilities and requires no stand-alone backup system.
UpdateAs of September 30, 2011, ERAM is only being used at 2 Facilities, Salt Lake ARTCC and Seattle ARTCC. The project is over budget and behind schedule. The system is being used at the two low traffic centers with many work-arounds and has not been implemented at the rest of the ARTCC's. Testing continues but Lockheed Martin is struggling to make the system work, the original implementation dates have been pushed back several times. There is a current push to implement ERAM nation wide in 2011 because of a promised software update that will address the many problems that plague the current system.
As of April, 2012, ERAM has been declared ORD at Salt Lake ARTCC and Seattle ARTCC.
As of August 20, 2012, nine of the twenty Air Route Traffic Control Centers (ARTCCs) are running ERAM operationally to control traffic. Five of the ARTCCs have achieved continuous operations with ERAM utilized 24/7 for air traffic operations (Salt Lake City, Seattle, Denver, Albuquerque, Minneapolis) in approximately 1.5 million square miles of airspace. All ARTCCs are running the ERAM release which includes the NextGen capabilities of Automatic Dependent Surveillance Broadcast (ADS-B) and System Wide Information Management (SWIM).
