Special VFR: what it is and how to request it
Special VFR is a clearance that lets you operate in a control zone with less than basic VFR weather. It is a useful tool with real limits and a few genuine traps.
What special VFR is
A clearance to fly in the surface area of controlled airspace (Class B, C, D, or a Class E surface area) with less than basic VFR minimums: at least one statute mile visibility and clear of clouds, instead of the usual three miles and cloud-clearance distances.
You have to ask for it
ATC will not offer special VFR — you request it: “Tower, Cessna One Two Three Four Five, request special VFR clearance to depart to the south.” They coordinate the airspace and clear you.
The minimums
One statute mile visibility and remain clear of clouds. At night, you generally need an instrument rating and an IFR-capable airplane to be granted special VFR at all.
The readback
Read back the clearance: “Cleared out of the Class Delta to the south, maintain special VFR conditions, Cessna One Two Three Four Five.” You are responsible for staying in special-VFR conditions.
The trap
It is legal, not always smart. One mile and clear of clouds near terrain or obstacles is genuinely marginal, and special VFR has hurt pilots who treated the clearance as permission to push into weather they should have waited out.
Where you cannot get it
Some busy Class B airports prohibit special VFR for fixed-wing aircraft; it is noted on the chart. Check before you count on it.
