In what conditions are SVFR operations authorized according to the regulations?

SVFR, or Special Visual Flight Rules, operations are governed by specific regulations that allow pilots to fly in conditions that are below standard visual flight rules (VFR) but above instrument flight rules (IFR) minima. The authorization for SVFR operations is particularly flexible when it comes to locations; they are permitted at any airport where such operations are not explicitly prohibited by existing regulations. This means that as long as the pilot has the appropriate visibility and is in contact with air traffic control, they can request and receive SVFR clearance in various airspace classifications, provided that safety is maintained.

This flexibility is crucial for pilots operating in constrained visibility situations, as it allows them to maneuver within controlled airspace under visual conditions, thus enhancing operational safety and efficiency. The other options imply limitations or specific conditions that do not align with the broader regulatory framework supporting SVFR, as they restrict the general applicability of SVFR operations across various locations and scenarios.
