That is why we need Cat3b. minima of 20ft vis of 150m. This is how Europe keep their Airports running. Try ZRH in the winter, they have far more 'fog days' than we do, snow and ice and yet seem to manage alright. This country is very Third World when it comes to Aviation. Even India has Cat2 where International Airports like OOL don't even have an ILS. I cannot think of one airport in the US that still has an NDB. The International Aviation Community consider Australia a backwater these days. Very sad compared to how we were once held.
