Definition
Aircraft operating in accordance with clearances within Class B, C, D, and E surface areas in weather conditions less than the basic VFR weather minima. Such operations must be requested by the pilot and approved by ATC, and require the pilot to remain clear of clouds with at least 1 statute mile flight visibility. At night, the pilot and aircraft must be instrument-rated and instrument-equipped to receive a Special VFR clearance.
Plain English
When the weather is too poor for normal VFR flying inside controlled airspace at an airport, a pilot can ask ATC for permission to fly under a relaxed set of rules: just stay out of clouds and keep at least one mile of visibility. ATC has to grant it, and at night you need an instrument rating and an IFR-capable aircraft.
Context Anchor
You may see this term when studying weather minimums, airport control areas, or ATC clearances for arriving or departing when visibility or clouds are below normal VFR limits.
Derivation
Special comes from Latin words meaning separated or set apart. Here it means this is not the normal VFR rule; it is a separate, specifically cleared way to operate under limited weather conditions.
Why Pilots Care
Gives pilots a legal way to continue a flight or reach an airport when standard VFR weather rules would otherwise force them to turn back or divert.
Grounding Statement
Picture a pilot near an airport on a hazy day: normal VFR is not allowed, but ATC may clear the pilot to proceed visually under the special VFR rules if the required conditions are met.
Intuition Check
Special does not mean the pilot can ignore the weather rules. It means ATC may allow a VFR flight under a separate, more limited set of rules.
Example Sentence 1
With the ceiling at 800 feet, the pilot requested a Special VFR clearance from the tower to depart the Class D surface area.
Example Sentence 2
With the ceiling at eight hundred feet, the instructor requested Special VFR Operations to depart the airport and remain clear of clouds.
