I've just tried a few unsuccessful landings at Dublin (EIDW). I just couldn't get the ILS working.I now know why.The default nav data in FSX lists the ILS at 108.9 the AIRAC 0908 charts I used listed it at 111.35. I'd got so used to relying on the AIRAC data that I'd forgot that FSX might not be up to date.I just wonder how many other obsolete nav aids are buried within FSX...... maybe one day we'll be able to update them.
