Not sure what you are looking at, but my download for tour 11 in the pdf says PACU, but the flight plan does not have it as a waypoint. It does have KWF, however. I do not have PACU in P3Dv4 nor any scenery from MM for it. Is this hidden somewhere other than the scenery files? There was no PTAM in the flight plan.
I even looked to see where others including you landed and the majority either landed at Waterfall or nowhere in particular if at all. Even you landed a at KWF.
