What is the appropriate unit of measure for wind reports in an aviation weather report?

In aviation weather reports, wind is commonly measured in terms of direction and speed. The direction is reported in degrees, indicating the compass direction from which the wind is coming, and the speed is expressed in knots. This standard measurement aligns with international aviation practices and ensures consistency in reporting across various regions.

Using tens of degrees for wind direction simplifies reporting while maintaining sufficient accuracy for operational needs. Knots, as a unit of speed, are widely used in aviation for wind reports because they are based on nautical miles, making them more relevant for flight operations than other units like meters per second or miles per hour.

This choice aligns with the conventions of aviation meteorology, where clarity and standardization are crucial for safe and efficient flight operations. Other units, such as miles per hour or metric units, are less common in an aviation context and do not provide the same level of compatibility with traditional navigation systems used in flight planning and operations. Thus, the use of tens of degrees and knots is essential for effective communication among aviation professionals.
