Fog prone?
I lived in Perth in the 90's and have been operating there for over 20 years.
That's like saying Cottesloe beach is shark infested.
One thing that the state government did do to entice Emirates to operate there was to put the ILS in on 03 (helps with ETOPS planning).
Cat II or better on 21 would be nice, but a better option would be to upgrade KAL, both airport and ILS, to handle a few widebody diversions. Then the operators would save money all year round without carrying tonnes of gas and have somewhere to go if it does go pair shaped.
Having operated into Kalgoorlie, l know in winter it can be a bitch sometimes, but with a Cat I it would be fine.
Albany has got one.
