During wind observation, how would you encode a wind gust that does not fluctuate by 10 or more knots?

In the context of wind observation within the Limited Aviation Weather Reporting System (LAWRS), wind gusts that do not fluctuate by 10 or more knots from the sustained wind speed do not necessitate specific encoding. The primary purpose of encoding wind gusts is to provide relevant information concerning significant changes that could affect aviation operations.

If the wind speed fluctuates less than 10 knots, it indicates a relatively stable wind scenario where the gusts do not represent a significant change from the average wind speed. Therefore, when reporting these conditions, there is no requirement to encode the gusts since they do not provide crucial or actionable data for flight planning or safety. This makes the choice of not encoding the gusts the correct approach, as it adheres to the standard practices for weather reporting.

This helps streamline reporting processes and ensures that only meaningful variations in wind conditions, which could impact aviation, are communicated.
