When reporting visibility of 3 miles in remarks, which coding is appropriate?

The appropriate coding for reporting visibility of 3 miles in remarks is coded as "VIS 3". This format is clear and concise, reflecting the visibility in statute miles as required in aviation weather reporting.

The use of just "3" after "VIS" is a standardized method in aviation meteorology to denote the distance in miles without unnecessary abbreviations or additional characters. This simplicity ensures that anyone reading the report can quickly identify the visibility, making it crucial for pilots and air traffic controllers who rely on accurate weather information.

Other coding formats may not conform to standard reporting practices. For instance, including "SM" (statute miles) could complicate the reporting unnecessarily since the value is already clear in the context. Similarly, using "03" may not be an accepted representation as it appears to reference a numeric value rather than directly indicating miles, and "3/2" could suggest a range of visibility that isn’t intended in this specific instance. Thus, "VIS 3" is the most appropriate and widely recognized format for reporting visibility of 3 statute miles in aviation remarks.
