So this guy was either flying the approach correctly or he was better than a dot deflected off the localizer and/or glide slope? Also, I think most 74 pilots and equipment are Cat IIIC qualified which may throw a monkey wrench into all of this.
Sorry - I don't do airplane-speak (grin). A correct approach is NOT over Honolulu itself, especially that low. The guide slope (if that's what I think it is) sounds about right if he were over the ocean coming into the airport, just a bit too far north...
