Definition
An ATC authorization permitting a pilot to operate under VFR within Class B, C, D, or E surface-area airspace when the weather is below basic VFR minimums. SVFR requires a clearance from ATC, requires the pilot to remain clear of clouds, and requires at least 1 statute mile flight visibility. At night, both the pilot and aircraft must be IFR-qualified and equipped. SVFR is used only for arrival to or departure from an airport within the surface area, not for cross-country flight.
Plain English
Permission from ATC to fly visually into or out of a controlled airport when the weather is too poor for normal visual flight, but still good enough that the pilot can stay clear of clouds and see at least one mile.
Context Anchor
Seen in weather, airport surface-area, and approach discussions, especially when comparing SVFR with contact approaches in instrument procedure material.
Derivation
The word special signals that this is an exception to normal VFR rules — granted only on request, only by ATC, and only inside the surface area of controlled airspace.
Why Pilots Care
It gives pilots a legal way to continue a visual flight instead of canceling or filing IFR when weather is below standard VFR limits but still safe to proceed by eye.
Grounding Statement
Picture a controlled airport under a low cloud layer: SVFR is the specific clearance that may let you move visually in or out while remaining clear of the clouds.
Intuition Check
“Special” does not mean easier, informal, or automatically approved. SVFR requires a specific air traffic control clearance, and it is not the same as a contact approach.
Example Sentence 1
With the ceiling at 800 feet, the pilot requested an SVFR clearance from the tower to depart the Class D airspace.
Example Sentence 2
With an SVFR clearance the aircraft departed the Class D airspace while staying clear of clouds and maintaining the required visibility.
