What are the requirements for a special VFR clearance?

The requirements for a special VFR (SVFR) clearance focus primarily on visibility and cloud clearance. A special VFR clearance allows a pilot to operate in controlled airspace during periods of reduced visibility while remaining in visual conditions. Specifically, the requirement of at least 1 statute mile visibility and the need to remain clear of clouds are crucial because they ensure that the pilot can maintain visual reference during flight, which is essential for safety in lower visibility conditions. This requirement is grounded in the regulatory framework designed to balance operational flexibility with safety.

The other options, while related to general aviation practice, are not requirements for obtaining a special VFR clearance. For example, filing a flight plan is not mandatory for special VFR operations, nor is there a minimum equipment requirement concerning navigation instruments specifically for SVFR clearances. Additionally, while pilots must operate under visual flight rules when using SVFR, the option’s phrasing suggests a misunderstanding of the necessary conditions, as SVFR clears pilots to operate in reduced visibility under specific guidelines rather than strictly adhering to VFR conditions.
