Hi Uplinker,
Just cause there's an ILS doesn't always mean that will always be the approach.
In Melbourne Australia the ATIS will sometimes quote "Expect ILS" or "Expect instrument approach" (eg VOR, Localiser, NDB, DME, RNAV, GPS etc) or possibly won't have any approach quoted if visual approaches are in use. Again it will depend on the runway and conditions of course.
Another point to consider is that the ILS will be used to start off the approach to get below the cloud or whatever conditions to then conduct a visual approach to final. In this case "Expect ILS" will probably be on the ATIS. The reason for this is the acceptance rate can be increased for visual approaches by using the ILS to start off, but if in IMC and full ILS approaches are needed the arrival rate will blow out and cause more delays.
Is that close to what you were after?
