# Why is a downwind wind speed given in wind checks for aircraft on final?

I have a quick question about wind checks. When I spotting at Sydney (YSSY), I often hear tower clearing aircraft to land and giving them spot wind checks at the runway threshold, all pretty standard.

What I don't understand is when that wind check contains a downwind component. For example:

QFA32, Wind 160/10 Downwind 2, Cleared to land RWY 16R


(That is an example and not a wind scenario I've heard.)

Am I overthinking this? Is the downwind component just given when they are landing with a tailwind?

• I'm not sure that's part of the wind information, it sounds more like something about the number of aircraft landing. But I may be wrong, if no one knows then it would be great if you could find an example on liveatc.net or somewhere else. – Pondlife May 15 '15 at 2:58
• Could you write exact wording you did hear/update with such wording when you hear it next time? Or find something in Live ATC (but I don't know whether it's available for Australia)? There might be some detail you are missing—and therefore failed to capture it in the example—that is important for interpretation. – Jan Hudec May 15 '15 at 4:44
• Yeah, I'm guessing he's actually saying "QFA32, Wind 160@10, number 2, cleared to land runway 16R" rather than "downwind 2". Unless of course you can't clear number 2 to land in Australia, in which case, ignore me... – falstro May 15 '15 at 9:20
