Key Takeaways:
- Special VFR (SVFR) allows VFR aircraft to operate in controlled airspace under weather conditions below standard VFR minimums (1 mile visibility, clear of clouds) without an instrument rating, but requires specific pilot requests.
- Fixed-wing SVFR flights receive significantly lower priority than IFR traffic and can cause substantial delays, as ATC must ensure the airspace is completely clear of other aircraft during their operation.
- Due to operational impact, ATC has discretion to deny SVFR requests, especially at busy airports, and pilots might consider a "popup IFR" clearance as a more efficient alternative if appropriate.
- Helicopters have more lenient SVFR rules, including no minimum visibility requirement, and can operate concurrently with IFR traffic under specific Letters of Agreement (LOAs) with ATC facilities.
