Which condition describes cloud cover categorized as "overcast"?

The term "overcast" refers to a specific condition in meteorology where the sky is completely covered by clouds, meaning there is a total cloud cover. This results in the sun being obscured from view and generally indicates that the entire sky is dominated by clouds, thus impacting visibility and atmospheric conditions.

In aviation, understanding cloud cover is crucial, especially for unmanned aircraft operations, as low-visibility conditions can affect flight safety and regulations under Part 107. "Full cloud cover" accurately describes this situation as it conveys that clouds fill the sky entirely without any gaps, which aligns with the definition of overcast conditions. Other levels of cloud cover, such as 7/8 or 1/2, do not fit the criteria for being classified as overcast because they indicate that there are still significant breaks or gaps in cloud coverage which do not obscure the sky completely.
