What? I've been flying professionally in the US for 20 years and the only time I've seen it done was for visuals into Denver, and I think that's been resolved a long time ago (it's been awhile since I've been there). We do it for single engine ops too, but fortunately I haven't had to see anything like that other than in the simulator.
