How are basic VFR weather minimums determined for a given flight?

• A. Basic VFR minimums are the same across all airspace
• B. They are defined by private company policies
• C. They depend on the airspace classification and are defined by regulation
• D. They apply only in Class A airspace

Answer: (C)

Basic VFR weather minimums come from the type of airspace you’re flying in. Each airspace class has its own regulatory minimums for visibility and cloud clearance, so the exact requirements change with where you are and how high you’re flying. Those minimums are defined by regulation and published in the appropriate rules and charts. In the United States, for example, the rules are laid out in FAR 91.155 and related sections, and the numbers differ between Class B, C, D, E, and G airspace. Also, VFR isn’t allowed in Class A, so the VFR minimums don’t apply there at all. So the correct concept is that basic VFR weather minimums depend on the airspace classification and are defined by regulation.
