Say you're VFR and approaching your destination airport, which is in Class C airspace. The ATIS is reporting IMC conditions, and you can see a layer of fog over half the airport (including the tower). However, there are only low scattered clouds over most of the 6000-plus foot runway. Okay, great...but what now? In Class C and D airspace (plus most of Class E below 10,000 msl), you must remain 1000 feet above, 2000 feet horizontally from, and 500 feet below clouds, and you need three (statute) miles' visibility.
