Which are the parameters for Visual Meteorological Conditions (VMC)?

• A. Ceilings at least 1,000 ft and visibility at least 3 statute miles
• B. Ceilings less than 1,000 ft and visibility less than 3 miles
• C. No ceiling and visibility unlimited
• D. Ceilings at least 2,000 ft and visibility at least 5 miles

Answer: (A)

Visual Meteorological Conditions mean you’re flying with references to the ground and can see-and-avoid other traffic. The standard minimums that define VMC in many training contexts are a ceiling of at least 1,000 feet and visibility of at least 3 statute miles. This combination gives enough vertical and horizontal visibility to safely maintain visual flight and separate from other aircraft.

If either the ceiling is lower than 1,000 feet or the visibility is less than 3 miles, you’d be outside VMC and would typically be operating under instrument flight rules or marginal conditions, depending on the airspace. The other options describe conditions that are either worse than the minimum (low ceiling and low visibility), nonsensical (no ceiling with unlimited visibility), or exceed the minimum (higher ceilings and visibility), but for the purposes of defining VMC, the minimums are the ones stated.
