Are there any airports with ILS working CATIIIC?
What do the charts for this procedure look like? Is there a missed approach procedure?
This is not implemented anywhere in the world.
As of 2012 this category is not yet in operation anywhere in the world as it requires guidance to taxi in zero visibility as well. Category IIIc is not mentioned in EU-OPS.
As far as I know NO airport in the world currently offers catIIIc as it has the most ridiculous minima both in the horizontal and vertical plane ...
There would still need to be a missed approach procedure, since plenty of things besides "not seeing the runway/lights" can cause the need for a go-around: equipment malfunction, traffic on the runway, winds shifting out of limits, etc. So no matter how "good" the approach is, it still has to have a defined missed approach procedure.
That procedure might well mirror the Cat I missed approach instructions. Not certainly, but they often do.
