What is a requirement for circling approaches conducted by high mins captains?

For circling approaches conducted by high minimums captains, the requirement that the approach need to be at least 3-1000 (3 statute miles visibility and a ceiling of 1000 feet) is critical to ensure safety. This minimum standard mitigates the risks associated with flying an approach when conditions are less than ideal, providing the captain with a sufficient visual reference for the approach and landing.

By requiring this specific visibility and ceiling, the procedure makes sure that the pilot has the necessary visual conditions to maneuver safely and maintain situational awareness during the circling portion of the approach. Adhering to this operational limit ensures compliance with regulatory requirements and promotes safe flying practices, particularly for those serving in high minimums captain roles, who may have additional restrictions due to experience or currency limitations.
