What does it mean when cloud cover is described as "Clear"?

When cloud cover is described as "Clear," it indicates that there are no clouds present in the sky. This classification is commonly used in meteorology to convey that the atmosphere is unobstructed by clouds, allowing for maximum visibility and sunlight. A clear sky typically suggests favorable weather conditions for activities that involve flying, such as drone operations.

Understanding the definition of cloud cover is essential for pilots and operators of unmanned aircraft because cloud conditions can significantly affect flight safety. Knowing that "Clear" means completely free of clouds helps in making informed decisions regarding flight operations, particularly when it comes to visibility and potential weather changes.
