I was based in Kansas City, Kansas, for Flying in the 1980s, and there is a pretty common winter and early-spring weather phenomenon in the Great Plains that creates very strong surface winds from the south with widespread low ceilings. At the time, New Century Airport had no approaches to the south, so we had to circle out of the ILS approach to Runway 36. Even with better than the one-mile visibility minimum, it was very uncomfortable to be flying downwind at 500 feet or a little less above the ground with a rip-roaring tailwind blowing during my turn to base, and then final, up toward Iowa. I flew the circle at near minimums only once in the dark and swore never again. And the terrain around that airport is very flat. Imagine a circling approach in hilly country and you can see why some pilots just won’t fly them.
