Definition
A set of reduced visibility and cloud clearance rules that allow a pilot to operate VFR within the surface area of controlled airspace when the weather is below standard basic VFR minimums. Special VFR (SVFR) requires an ATC clearance, at least 1 statute mile flight visibility, and the aircraft must remain clear of clouds. SVFR is available only in Class B, C, D, and E surface areas, only during the day for most operations (night SVFR requires the pilot to be instrument rated and the aircraft to be IFR equipped), and is not permitted at certain busy airports listed in 14 CFR Part 91, Appendix D.
Plain English
A special set of easier weather rules that lets a pilot fly into or out of an airport's controlled airspace when the weather isn't quite good enough for normal VFR flight. The pilot must ask air traffic control for permission, must be able to see at least one mile, and must stay out of the clouds.
Context Anchor
Seen when deciding whether a visual departure, arrival, or airport-area flight is allowed when the weather is below basic VFR minimums in controlled airspace around an airport.
Derivation
Special' here means an exception to the normal rules — a separate, narrower set of conditions granted only when requested. It does not mean 'better' or 'more advanced'; it means 'set aside from the standard.'
Why Pilots Care
Enables continued VFR flight and airport access in controlled airspace when standard weather minimums are not available, while still requiring ATC approval to preserve separation and safety.
Grounding Statement
Picture a low-cloud day at a controlled airport: normal visual flight is not allowed, but ATC may clear a pilot to move through the area if the pilot can stay clear of clouds and meet the Special VFR visibility requirement.
Intuition Check
“Special” does not mean the pilot can ignore the weather rules; it means a specific ATC-cleared exception may apply. “Minimums” are not comfortable conditions—they are the lowest legal conditions allowed for that operation.
Example Sentence 1
With the visibility reported at 2 miles and a broken layer at 800 feet, the pilot requested Special VFR to depart the Class D surface area and climb on top.
Example Sentence 2
Operating under Special VFR weather minimums, the aircraft maintained one mile visibility while remaining clear of clouds inside the control zone.
