What does "CAVOK" indicate in aviation weather reports?

The term "CAVOK" stands for "Ceiling And Visibility OK," which is a standardized reporting term used in aviation weather reports. When CAVOK is reported, it signifies that the weather conditions are generally good, indicating that visibility is at least 10 kilometers, there are no significant weather phenomena, and there are no clouds below 5000 feet above ground level or below the minimum safe altitude for the area. This term helps pilots determine that they can expect favorable flying conditions without worrying about obstructions or poor visibility.

Understanding CAVOK is essential for pilots as it directly impacts their flight planning and ability to safely navigate through airspace. Accurate interpretation of weather conditions is critical for operational safety, and CAVOK provides confidence that the weather is settled and suitable for flying.
