In terms of communication, what does the term "CAVOK" mean?

The term "CAVOK" stands for "Ceiling And Visibility OK." This is a standard aviation meteorological term indicating that the weather conditions are generally good for flying. Specifically, it means that the visibility is at least 10 kilometers, and there are no significant clouds or weather phenomena that might affect flying safely. CAVOK conditions imply that there are no cloud layers below 5,000 feet above ground level or below the minimum sector altitude and that there are no significant weather phenomena like rain or storms in the reporting area.

Understanding CAVOK is crucial for pilots and air traffic control as it communicates a specific state of weather that is favorable for flight operations, minimizing uncertainties regarding visibility and the presence of clouds. This ensures safer flight planning and operations.
