Key Takeaways:

Special VFR (SVFR) allows VFR pilots to operate in Class B, C, D, or E airspaces below 10,000 feet when weather is below standard VMC (e.g., 1 mile visibility, clear of clouds), serving as an alternative to IFR for short periods.
SVFR approval is entirely at ATC's discretion and is subordinate to IFR traffic, meaning clearances can be denied or revoked if they would delay IFR operations, often requiring "one in, one out" separation for fixed-wing aircraft.
While offering flexibility, the article strongly recommends SVFR only for proficient instrument-rated pilots due to the inherent safety risks of operating in marginal weather, despite lower day-time pilot qualification requirements.

Special VFR (SVFR) is a clearance that pilots can use to fly VFR into an airspace reporting below VMC. SVFR allows pilots to operate in and out of Class B, C, D, or E airspaces below 10,000 feet when the reported weather is below normal VFR. It is a great tool when used correctly, and frees a pilot from needing an IFR clearance when they can maintain special VFR conditions for a short time. You should understand SVFR, but also evaluate it critically in terms of your own capabilities and limitations.

Depending on the facility, ATC will provide the appropriate service for SVFR aircraft when operating near IFR aircraft. In the tower, we treat SVFR aircraft (lacking a Letter of Agreement, LOA) similar to IFR aircraft due to the low-visibility permitted for SVFR. The best way we remember it is, “One in, one out.”
