MR, there aren't many "farms" on the 32 approach - it is built-up all the way from the coast. Not high-rise like the northern end, but densely populated residential areas nonetheless. Haven't seen cows in Banora Point for a long time.
C100driver, I understood it was GCAL that was pushing for the installation of an ILS? My guess it is mainly for the asian carriers, seeing as the domestic carriers are (or soon will be) RNP capable, as you pointed out. I also thought AA was paying for it - do they recoup the cost from the airlines? Sorry for all the questions, I'm just trying to work out how it all works.
