What does "BKN" denote when included in a TAF?

• A. How many clouds are present
• B. Broken clouds
• C. Heavy cloud coverage
• D. Cloud height above the surface

Answer: (B)

The term "BKN" in a TAF report stands for "broken clouds." This indicates that 5 to 7 oktas (eighths) of cloud cover are present in the sky. In aviation weather reporting, cloud coverage is characterized in terms of oktas, which helps pilots and meteorologists assess visibility, flying conditions, and the potential for weather changes. Understanding the specific term "BKN" is important because it conveys crucial information about the sky conditions that can affect flight operations. For example, broken clouds can impact flight visibility and may be relevant for takeoff and landing considerations. The other options do not accurately represent the meaning of "BKN." While they relate to the cloud coverage, they do not specifically detail what "broken clouds" entails or how it affects aviation operations. Hence, recognizing "BKN" as broken clouds is essential for interpreting TAF reports correctly.
