If the observed prevailing visibility is determined to be 32 statute miles, what visibility would be reported?

When determining the visibility to be reported in aviation weather, it is essential to understand the relevant reporting standards. In this case, if the observed prevailing visibility is calculated to be 32 statute miles, the reported visibility must conform to the conventional rounding rules used in aviation meteorology.

According to these standards, visibility is rounded to the nearest whole number, and then if the number is greater than a certain threshold, it may be adjusted to fit into specific reporting conventions for readability and practicality. For ranges beyond certain limits, common practice is to report values in 5-mile increments or to round to the nearest 5.

In this scenario, since the observed value of 32 statute miles falls between 30 and 35, the rounding conventions dictate that the reported visibility would be rounded down to 30 statute miles. This value aligns with aviation reporting practices, where visibility is expressed in the simplest terms for clarity and ease of communication.

Thus, the reported visibility in this instance, given the observed conditions, would be most appropriately noted as 30 statute miles.
