Which of the following is NOT a feature of ERAM?

• A. Conflict detection
• B. Routing capabilities
• C. Real-time weather forecasting at the ground
• D. System reliability metrics

Answer: (C)

ERAM is designed to automate and modernize en route air traffic management by providing the tools controllers use to manage traffic safely and efficiently. Its strengths lie in detecting potential conflicts between flights so they can be resolved early, offering routing capabilities to optimize flight paths and sequencing, and delivering system performance and reliability data to monitor how the automation and infrastructure are performing.

Real-time weather forecasting at the ground is not something ERAM generates or provides. It may display weather data and feed weather information from external sources to help situational awareness, but it does not create weather forecasts. Forecasting requires meteorological models and expertise outside the automation of en route routing and conflict detection, which is why this item is not a feature of ERAM.
