Under what condition does LVOP get terminated?

The termination of a Low Visibility Operations Plan (LVOP) is specifically linked to the criteria that define how long visibility has been above certain thresholds. In this case, the condition for LVOP termination is when the Runway Visual Range (RVR) improves to greater than 1200 meters for a sustained period of 15 minutes.

This is significant as it indicates a stable and adequate visibility condition for safe aircraft operations, which is critical during low visibility scenarios. The longer duration of 15 minutes is designed to ensure the improvement in visibility is consistent and reliable, which is essential for decision-making in air traffic management and ensuring safety.

The other options do not meet the established criteria for terminating an LVOP, as shorter times or different visibility measurements do not guarantee that conditions are safe enough to resume normal operations. Understanding these thresholds helps ensure that all personnel involved in airside operations are aligned with safety protocols under varying weather conditions.
