What does "CAVOK" mean in a METAR report?

• A. Ceiling and visibility okay
• B. Cloud coverage at visibility okay
• C. Clear air visibility okay
• D. Ceasing aircraft visibility okay

Answer: (A)

CAVOK is an abbreviation used in METAR reports that stands for "Ceiling and Visibility OK." This term indicates that visibility is good and there are no significant weather conditions affecting the area, such as clouds below 5,000 feet or visibility less than 10 kilometers. When CAVOK is indicated, it signifies that pilots can expect a clear sky with no obstructions or hazardous weather, which is crucial for flight operations. In contrast, the other choices do not accurately capture what CAVOK represents or include additional terms or conditions that can lead to confusion. The use of CAVOK is standardized to provide a clear and concise assertion about the atmospheric conditions conducive to safe flying.
