We have a sloping runway. We tend to land uphill if the tailwind is 10kts or less. The slope quickly devours the excess groundspeed.
Likewise, it's common for aircraft to take off downhill if the tailwind is light.
We still get visitors who struggle to get their heads round this and insist on landing or taking off into wind regardless. I've seen them 4 up and full fuel take an uphill departure because it gives them a three or four knot h/wind.
It's often entertaining to watch.
