Which term indicates that visibility is at least 6 statute miles in a TAF?

The term that indicates visibility is at least 6 statute miles in a Terminal Aerodrome Forecast (TAF) is VFR, which stands for "Visual Flight Rules." VFR conditions are defined by having sufficient visibility and cloud cover, allowing pilots to fly by visual reference rather than relying solely on instruments. Specifically, VFR indicates that the visibility meets or exceeds 3 statute miles and the cloud ceilings are adequate for safe flying, with the key aspect for this question being that visibility is at least 6 statute miles.

In contrast, other options represent different categories of flight rules based on visibility and cloud conditions. MVFR stands for "Marginal Visual Flight Rules" and usually indicates visibility between 3 and 5 statute miles, combined with specific cloud cover requirements that are more restrictive than VFR but less so than IFR. IFR, or "Instrument Flight Rules," applies when visibility is less than the minimum required for VFR conditions, making it necessary for pilots to rely on instruments. Lastly, SVFR, or "Special Visual Flight Rules," allows pilots to operate under conditions that are less than standard VFR, but it is still a framework for visual navigation that requires special permission.

This understanding helps clarify why VFR is the correct indication for
