How did I do for a non-airline guy?
Proved my point.
Jetstar uses RNP down to .3 at OOL and it gets us down to 439'. .11 will get us to 367'. We also use it in BN.QF use RNP approaches in preference to ILS on most occasions but a QF pilot could give you more detail. GBAS ILS like approaches are already being trialled in Sydney. Reading stuff on RNP and using it on a regular basis are not the same thing. I'm not trying to be superior but I do get annoyed when people make statements about airline operations and procedures that they really do not know much about. The long term future for ILS will be to go the way of the NDB.
I don't disagree with the argument for having an ILS installed but someone has to agree to pay for it and I can't see too many hands going up.
