Definition
A VFR flight cleared by air traffic control to operate within a control zone in meteorological conditions below the standard VMC minima. Special VFR is authorized only when requested by the pilot and approved by ATC, and operations are conducted under VFR but with reduced visibility and cloud-clearance requirements specified by the controlling authority.
Plain English
A special permission from ATC that lets a pilot fly under visual rules inside a control zone even when the weather is worse than what visual flight normally requires. The pilot must ask for it, and the controller must approve it.
Context Anchor
You may see this term in ICAO-based rules, international flight operations, or air traffic control clearances involving flight near an airport in reduced weather.
Derivation
VFR stands for Visual Flight Rules. 'Special' here means a specific exception granted on request — not a higher-quality version of VFR. The ICAO tag indicates this is the international definition used by the International Civil Aviation Organization, which may differ slightly from the FAA's domestic version.
Why Pilots Care
It provides a legal way to continue a visual flight instead of canceling or switching to instrument rules when conditions drop just below standard limits.
Intuition Check
“Special” does not mean casual or automatically safer. It means ATC has granted a specific exception to normal visual flight weather limits in that controlled area.
Example Sentence 1
With the ceiling at 800 feet and visibility two miles, the pilot requested a Special VFR clearance to depart the control zone.
Example Sentence 2
Because the ceiling was below the normal VFR minimum, the student pilot asked for a special VFR flight clearance before continuing to the airport.
