Please God its not because we are avoiding the built up areas on approach!
That’s precisely why it’s done.
The RNAV GNSS and all three RNP-AR to CBR 35 are all coded at 3 degrees so heights are the same to a 50’ TCH.
Which all seems to confirm it's a bit of a wank - 500 mts (at absolute best) to the west is doing bugger all for the noise envelope.
Is there an advantage with the minima on the RNP-AR approach versus the "normal" GPS approach? If not, what is the advantage?
