It was in an on-line test, so don't have the details any more. It was a single sentence Q with no accompanying chart, just the V.....
I know all about the wind eg. 260/15 250V33- (where the variation is >=60 degrees).
Now if that is the answer, it is very sneaky in the context of the question because it did not relate to decoding METARs and TAFs. Just what does the symbol V refer to?
I'll keep looking and let you know what, if anything, further I can find.
In the meantime, I'm all ears..........
