Which is why we invented RNP.........
The original QF RNP charts had curved approaches down to 200’ . Everywhere. Then the geniuses at AirServices decided that it was no good having QF only doing these special approaches. Generic, all type , all operator approaches were the solution! Minima shot up to around 700’.
Useless. The technology is way ahead of the regulators. Cat 3 GLS has been demonstrated . ILS installations will soon be stranded assets.
Which is great in theory in your jet but still useless to the predominate users of the airfield, Saab’s, Dashes and GA.
