ERAM stands for which En Route Automation system?

• A. Electronic Route And Mapping
• B. En Route Automation Modernization
• C. Emergency Route And Management
• D. En Route Allocation Model

Answer: (B)

ERAM stands for En Route Automation Modernization. This name captures its purpose: upgrading the automated tools used by air traffic controllers while aircraft are between the terminal areas, across the en‑route centers. The system provides a modern, integrated data environment that replaces older en‑route automation, enabling higher capacity, more accurate flight data, improved conflict detection, and smoother handoffs between centers. It supports trajectory‑based operations and data sharing across facilities, aligning with NextGen goals. The other terms don’t describe the actual system used in en‑route automation, so they aren’t correct expansions.
