That Cork one is very strange. It doesn't really look like a map and I would be hesitant to georeference it as I think it could result in some confusion. I agree the Dublin one would be georeferencable but unless there are a few others like Dublin, I couldn't justify switching this on really.

Thank you, I will look to see why the runway surfaces are not coming through correctly.

Could you give an example of an aerodrome chart which you think would be good candidate for georeferencing?

Just noticed that the surface type seems to be missing for Airports in Ireland. I've looked at Dublin, Weston, Donegal - all with unknown surface, but the surface is in the AIP for each. For example, the Dublin surface is in 2.12 in the textual part of the AIP.
