Study Notes
- En Route Automation Modernization (ERAM) replaces current computers and displays.
- ERAM is being installed in selected Air Route Traffic Control Centers (ARTCCs).
- ERAM is a modular system designed to provide controllers with the functionality of the current system; it can be easily upgraded as the ATC system transitions to NextGen.
- ERAM makes radar data and flight plan information available to every controller.
- Controllers will be able to share and coordinate information between centers, and between centers and towers.
- Increased surveillance accuracy should enable 3-mile en route separation, instead of 5-mile separation.
- Handoffs will be performed more automatically.
- ERAM allows upgrades to the NAS system as innovations become available.
- ERAM system software will initially provide the same features as currently exist based on an open architecture/language to permit simpler future upgrading.
- One of the first planned enhancements for ERAM is end-to-end, four-dimensional trajectory modeling.
- This trajectory modeling predicts the path of each aircraft in time and space from departure to arrival airport.
- As flight operations transition from ground-based radar to ADS-B tech, aircraft can fly more flexible and efficient routes without overloading the ATC system.
- ADS-B should enable closer spacing of aircraft.
- Reducing en route separation from 5 to 3 nautical miles should match that available in the terminal environment.
- ERAM software and hardware will be upgraded in phases.
- Early installation began in 2009, followed by enhancements each year.
- Advanced capabilities planned by the FAA include:
- Integration of weather data into trajectory modeling
- Enhanced conflict prediction and resolution
- A data link that provides more secure and accurate communications
- Airspace flexibility functions that will dynamically adjust airways, airspace, and sectors in real time to meet changing traffic needs
