Just some info, to add depth to the discussion.
1. Gold Coast are not putting in hial for 14 approaches. They don't have the real estate for it. Unfortunately, this doesn't help. As has been stated the problem at Goldy is vis more than cloud base.
2. The current Naverus rnp approaches for Qantas have a roll out point at 2 mm from threshold, with rd turn before it. The icao ones coming later in the yr will be same.
3. There have been rwy aligned rnavs already designed for 14. Final at 5nm with 10-15° turn. The designs have been floating around for 3yrs, but can't be implemented due noise issues. If ils gets approved, then new rnavs will come.
4. Thankfully the terrain environment to the south will not have a bad impact on rnp-at missed approach.
5. Generally rnp minima is about 100-150ft higher than ils, and about 100ft lower than rnav. The difference at Goldy will be Currumbin hill and how accurate survey data we can get.
6. I didn't say it wasn't going to happen. But there is a long journey still to go, as technology develops there might not be a need for one. Gbas is about to go live at yssy. Gbas would allow us to solve a lot of problems at the Gold Coast.
