KC10, I think you need to reread my question and look at the Jep EGLL ILS DME 27R approach plates. They do not have step downs for me to do a conventional dive and drive LOC approach.
Bigtime you actually answered my question. For me to be able to do a LCO approach, you are right, it has to say ILS or LOC DME 27R approach. And no it does not say that. It says "ILS DME RWY 27R" That's what threw me off actually, I flipped through ILS charts in North America and I've yet to find one that ILS only. All of them has "ILS OR LOC". I looked at IAH, MEX, YUL, MSP. The only time you see ILS only is when it goes to Cat II in which case no LOC minimums are publlished. Which makes me wonder why LOC minimums are publised for an ILS only approach plate?
