When I listen to this argument go back and forth between residents/pollies and the Goldie Airport Corp I've come to the conclusion this is only about money for the Airport itself. Their reasoning is that they want to be competitive to Brisbane by enabling aircraft to land when the weather is inclement.. yep I get that. They also want to encourage the asian carriers to fly in. The Asian carriers can't or don't want to do RNP approaches for reasons that I don't know. I'm presuming they aren't the capable of RNP at this stage. Will they be in the future ??? If thats the case the ILS will be a waste of money.
The residents are beside themselves with the increase in noise as ASA intend to leave the ILS operational 24/7. ASA won't do any "try before you buy" trials.
In my view, on the rare days that the wx is continually lower than the RNP/GNSS/VOR minimas use it then. This will minimise the effect on residents affected from this new flightpath.
