I am trying to comprehend an OpSpec that says "All conditional forecast elements below the lowest applicable operating minimums must be taken into account."

While I can assume this means anything in a TAF below mins counts in disqualifying an airfield, I cannot take the leap from assumption to absolute certainty without understanding factually the definition of "conditional forecast elements".

Google and searching here yielded a few nebulous answers half-answers:

• TEMPO in WX forecast? - PPRuNe Forums
• http://www.nws.noaa.gov/directives/s...008013curr.pdf This document mentions "conditional language".

But, what is the actual definition of "conditional language" and what would be an example of such? I just haven't found any official government documents that define conditional language or provide examples in a TAF.



Thanks guys.
