Have been flying to Spain today and here is a small example of what can happen.
I dont want to identify the airport but it's big and on the Spanish coast. Today 8th June a new ILS and associated procedure is promulgated on the South easterly runway and indeed the NOTAMS also mention this fact. So we brief for the new ILS - the ATIS is saying RW 12 etc. As we join the arc we find the ILS is not coding or showing. I ask approach if the ILS is working to be told negative, cleared for the VOR/DME approach.
Now the weather was good (Cavok, day) but it would have been nice if the ATIS had said "ILS off air, expect VOR/DME approach to RW...etc.
