What visibility is required for Special VFR operations?

For Special VFR (SVFR) operations, the regulation requires a minimum visibility of 1 statute mile. This allows pilots to operate in reduced visibility conditions that would not meet the standard Visual Flight Rules (VFR) requirements. Special VFR is typically used when visibility is less than the VFR minimums but greater than what would render it unsafe for visual navigation.

In Special VFR, pilots must also remain clear of clouds, which ensures that they maintain visual reference to the ground or other landmarks. It’s important for pilots to use caution while operating under these conditions, as flying with limited visibility increases the risk of encountering obstacles or flying into less favorable weather conditions.

The other visibility options are more stringent than what is mandated for Special VFR operations. For instance, a requirement of 3, 5, or 10 miles would not be appropriate since these distances exceed the minimum necessary for SVFR, where only 1 mile is required to maintain a visual reference in lower visibility circumstances.
