John2010:networkn: It does means that it's less safe to fly those airlines to those destinations however.
As someone who has had more than a little experience with aeronautical nav systems in a number of countries, including managing the design of approach and departure procedures, I can tell you that your claim is, as is becoming typical with your claims, entirely incorrect.
Well perhaps rather than being negative and condescending, you could clarify the situation for the education of those here who might be interested.
To my understanding, which I am prepared to be wrong about, rather than not having the navigation equipment, Qantas/JS planes don't have compatible Nav equipment to allow them to fly into Qtown and Wlgtn airports under specific weather conditions. To my way of thinking, having incompatible systems when you fly to those destinations seems very strange. I feel it reasonable to presume the systems in Wellington and Queenstown are there for good reason, and flying into those areas without them makes them relatively less safe (What if they needed to make an emergency landing (rare I admit), where those systems could provide additional information and guidance, making it.. RELATIVELY Safer.
I have a recollection of a Qantas jet, I think last year, which had nav systems failure of some description (Radar perhaps), and had to be led home by a AirNZ jet? I suspect different cases/nav system issue?
