If you’re talking recently, it’s because with 22L/4R closed using 29 means we don’t have to do single runway ops. When we can’t use 29 we have to provide 5-7 mile gaps on the final so tower can get departures out. Runway 29 is closed overnight for constructions and opens again around 645-7am local.
Personally, there’s been a lot of times I think we should be doing RNAV X 29 and 4L instead of Stadium Visual 29 and 22R, but that means tower has to do a little more work so they won’t do it unless the winds are really bad.
