What should be done when visibility is less than 1 mile for SVFR fixed wing operations?

When visibility is less than 1 mile for Special Visual Flight Rules (SVFR) fixed wing operations, informing departing aircraft that clearance cannot be issued is the appropriate action. This policy is in place to ensure the safety of both the departing aircraft and any other traffic in the vicinity, given that low visibility conditions can severely impact a pilot's ability to navigate and see other aircraft, landmarks, and the runway.

In such conditions, the air traffic controller has the responsibility to prioritize safety over issuing departures. Clearances in low visibility situations require a comprehensive understanding of the traffic and operational environment, which may not be feasible when visibility is compromised. Thus, controllers must take the necessary steps to prevent aircraft from departing if they cannot do so safely.

By communicating this limitation effectively to departing aircraft, controllers can mitigate risks associated with low visibility scenarios and ensure that all movements within the airspace are conducted safely and in accordance with regulations. This decision aligns with the standards for managing traffic under challenging weather conditions and upholds the safety protocols inherent in air traffic operations.
