OKC465:
Since you mention PSP...
You know, rather than change the whole amazing spiral down RNP AR (Y or Z) to 13R for the displaced threshold, they just recoded the new RW13R threshold waypoint into the existing procedure, resulting in a 'noticeably' shallower vertical path from NUDCI inbound.
What is that path? It doesn't show any path change on my Jepp chart from NUDCI inbound.
Must be some high rollers living off the approach end of 13R.......
How's that? A shallower path would yield more noise. In any case along the final segment to 13R there old, cheap housing, then further out a whole lot of power-generating windmills.
