If overhead marshal is used, how often shall EEATS occur?

The correct frequency for conducting Enhanced Enroute Air Traffic Services (EEATS) when overhead marshal is utilized is every other minute. This timing is crucial because it allows for a more efficient use of airspace and ensures that air traffic controllers can maintain a clear and updated understanding of aircraft positions and intentions. By performing EEATS every other minute, controllers can manage traffic effectively while minimizing the risk of congestion. This practice aligns with safety protocols that aim to keep flight paths organized, particularly when an overhead marshal monitoring system is in place, which is designed to streamline flight operations and reduce the workload on air traffic controllers. In scenarios where aircraft are grouped closely, having real-time updates every other minute keeps all involved parties informed of any necessary adjustments in flight paths or altitude, ensuring safe and timely operations.
