Narrative:

We had held for one half hour waiting for the winds to change and or die down enough to get a 10 KT or less tailwind component. We finally made the approach and got a wind check on short final. (Widebody transport maximum demonstrated tailwind component is 10 KTS). The winds were approximately 130 degree at 12, 13, or 14 KTS and changing by the second as winds always do. The figure (velocity) I heard using the crosswind/headwind chart showed we were 1 KT over the 10 maximum tailwind component. I asked the captain what his intentions were and he said he heard 1 KT less in the velocity than I heard and we were going to land. The runway is over 12000 ft long and safety was never an issue or problem. It could only be a problem if ATC personnel choose to make waves. The captain used some reverse thrust even though we briefed for the sydney airport's required operation of idle reverse thrust before the approach.

Title: WDB LANDS WITH TAILWIND IN EXCESS OF LIMITS.

Narrative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
