What condition requires issuing official ceiling and visibility to VFR aircraft?

• A. Weather above VFR minimums
• B. Weather below VFR minimums
• C. Weather with broken clouds only
• D. Weather with winds calm

Answer: (B)

The key idea is that VFR flight depends on meeting certain weather minimums for visibility and cloud ceiling. When the weather drops below those VFR minimums, pilots can no longer operate VFR safely, and ATC must convey the current weather in terms of the ceiling and visibility to VFR aircraft so they understand the conditions they’re flying in. The ceiling is the height of the lowest cloud layer that covers the sky, and visibility is how far a pilot can see. So, in conditions that are below VFR minimums, ATC provides the official ceiling and visibility to help pilots assess IFR alternatives (such as an IFR clearance) or Special VFR if allowed. If the weather is above VFR minimums, those specific ceiling-and-visibility figures aren’t required for informing VFR operations. Winds alone don’t trigger that requirement, and simply having broken clouds or calm winds isn’t the factor by itself.
