Where to find information on ILS categories at European airports? I have a list of airports in Europe and I need to find up-to-date information about ILS categories (I, II, IIIa, IIIb or IIIc) at these airports. Does anyone know where I could find such data efficiently?
The information you are after is, unfortunately, rather distributed.

Eurocontrol maintains a useful list of websites ordered by state, found here:

European AIS

Or by registering for an EAD Basic account you can access the European AIS Database in a more centralised and user friendly way, found here:
