Under what condition can a high mins captain depart to a destination with RVR below 1600?

A high mins captain is an individual who has specific limitations on the minimum visibility criteria they can use for departures. According to the regulations in place, these captains typically require a minimum Runway Visual Range (RVR) of 1600 feet for departure unless certain conditions permit a lower RVR.

When a take-off alternate is provided, the high mins captain has the option to depart to a destination with RVR below the standard 1600 feet requirement. This is because the presence of a take-off alternate ensures that the flight has another airport to divert to in case conditions at the intended destination fall below acceptable limits after departure. This alternate serves as a safety net that enhances operational flexibility and supports decision-making in low visibility situations.

The other options do not align with the regulations for a high mins captain. Providing an alternate airport with lower visibility does not meet the required standards for departure. The need for weather conditions to be at or above specified requirements directly contradicts the scenario of departing with an RVR below 1600. Finally, performing a Category II approach pertains to landing rather than departure criteria, and while it allows for lower visibility landing conditions, it does not affect the take-off visibility requirements for high mins captains.
