Definition
An ICAO term for a VFR flight cleared by air traffic control to operate within a control zone in meteorological conditions below the standard VFR minima. The flight proceeds under VFR rules but with a specific ATC clearance that authorizes operation in weather that would otherwise require IFR.
Plain English
A special permission from ATC that lets a pilot fly by visual reference inside a controlled airspace around an airport, even when the weather is worse than normal VFR rules allow.
Context Anchor
You may see this term in air traffic control procedures, weather-related clearance discussions, and operations near controlled airports when the ceiling or visibility is low.
Derivation
‘Special’ comes from Latin specialis, meaning ‘particular’ or ‘individual’ — fitting, because this clearance is granted case by case rather than as a standing right. ‘VFR’ stands for Visual Flight Rules. Together: a particular VFR clearance issued for conditions that fall outside the normal rules.
Why Pilots Care
Allows continued visual operations in controlled airspace without requiring an IFR clearance when conditions are below basic VFR but still safe.
Intuition Check
“Special” does not mean the pilot gets to ignore the weather rules. It means ATC has issued a specific clearance that allows limited VFR operation in weather below normal VFR minimums.
Example Sentence 1
The pilot requested Special VFR to depart the control zone when visibility dropped below the standard VFR minimum.
Example Sentence 2
With one-mile visibility reported, the controller cleared the helicopter for Special VFR Flight into the Class D airspace.
