Many thanks. The new software should accept all higher reported visibilities and accept them, marking the station as having reported the 30SM min visibility. Hence, the new code should adjust dynamically and accept all such station reports.

OK great. The only issue is when stations who can report more than 15SM report 15SM because then Opus uses the visibility set in the options. Although with regards to CYUL they only seem to report 15SM or 30SM so that really isn't a problem. With some stations that seem to report 15SM, 20SM, etc that could create an issue.

 

Thanks again!

I usually have my default surface visibility set to 32km (20 miles) anyway and recommend others do the same unless they know the default should be more. When set to 32km (20 miles) then the reported 15SM, 20SM, or 30SM don't cause any unwanted effects. 15SM will give 20SM actual, and 30SM will give 30SM. Both are really as expected with perhaps an extra 5SM visibility at the first site. But since they might be using 15SM to mean 15 miles minimum then it really does not matter. Anyway it is not possible to categorise every single met station assigning different procedures to each. Nor is such a thing desirable in real life. You could say it must add a certain amount of uncertainty to flying in Canada, do the pilots carry a list describing how to interpret each stations visibility report. I doubt they do so 15SM should make sense to all pilots without any confusion.

Thank you for the response Stephen. I will set my visibility to 20SM.

Should help in these situations.
