Frankfurt operations question.

[Malybenek]

As far as I know, typical conditions for Frankfurt are:
westerly winds, arrivals 25L and 25R, departures 18.
These three streams of traffic can be nicely handled (sort of independently).
However, I've learned that if the tailwind component on rwy 18 exceeds 5 knots, the runway is closed so we sort of lose one runway.
Question:
Doesn't it impede on the planned capacity of the airport?
How do ATC cope with it?

Thanks for any inputs.

Think the tail wind limit on 18 is 15 knots not 5 knots which massively reduces the chances of it being out of action. When it is out of action delays do build.

Taken off in a A319 on 18 with a wind of 360/14. Our limit is 15 knots tailwind component and as the runway is 4000m long we had little problem getting airborne in less than half the available bumps...sorry I meant to say concrete.
