Under what condition can special VFR operations be authorized at airports in Class D airspace without reported ground visibility?

Special VFR operations in Class D airspace can indeed be authorized if the flight visibility is at least 1 statute mile (SM). This allows pilots to operate when weather conditions are not ideal for standard VFR operations, which typically require a minimum visibility of 3 SM. However, special VFR provides a way to conduct operations under less restrictive visibility requirements, provided that the pilot can maintain visual separation from obstacles and other aircraft.

The conditions for special VFR to be granted include the requirement for at least 1 SM visibility and the ability to remain clear of clouds. It is crucial that pilots are aware of the specific conditions under which special VFR is applicable to ensure safety while flying. The ability to maneuver in less than favorable conditions can be particularly beneficial in busy airspaces where waiting for favorable weather could lead to extended delays.
