STL 11-11.....what is the missed app pt?
EGE 11-1...what is the missed app pt?
DCA 11-3...what is the missed app pt?
ROA LDA w/GS Rwy 6 (don't have the index #) ...what is the missed app pt?
What's the mystery here? The approach charts clearly show the missed approach point.
As discussed, The STL 11-11 chart shows the MAP at REVRY at 5.1 DME. The procedure notes also state that the localizer is unusable beyond this point.
Now, on the STL approach in the lower left below the GS angle it says "MAP at REVRY/D5.1 IRMK" and there is an "M" at REVRY on the profile view. Standard stuff if this approach could be flown with the GS OTS, but note 3 specifically prohibits the procedure if the GS is OTS.
What has the glideslope to do with the matter? Nothing. The procedure, as you have noted, cannot be flown without the glideslope. There is one missed approac procedure, the approach cannot be flown without glideslope, and the localizer is unuseable beyond the MAP. I can't see any room for a question or discussion. It's clearly published with no ambiguity.
The EGE 11-1 chart shows a decision altitude of 8330 on the glideslope, from which the missed approach will be executed. Without the glideslope, the missed approach will be executed at CIPKU at the 3.5 DME point on the localizer. Again, very clear.
The KDCA 11-3 chart shows a missed approach at a minimum descent altitude of 1100' with or without the glideslope, to be commenced at 3.5 DME. Again, no ambiguity. With a glideslope, one may ride the glideslope the minimums, and without it one may descend to 1100' immediately after passing MINIE at 6.0 DME, if desired...but the MAP doesn't change.
The KROA 11-2 chart shows a missed approach point at 1580' on the glideslope, or at JOKNI at 1.4 DME without a glideslope available. Again, quite clear.
With this in mind, what is the source of confusion?

Standard stuff, period.
So why is this information there???? Contradictory and confusing at the very least....
Are you confused by the entry "MAP at REVRY/D5.1 IRMK?"
As you noted, there is no provision for conducting this approach without the glideslope. Therefore,the usual information that would occupy that line (to be accompanied with times from the previous waypoint to the MAP, for nonprecision purposes where the option is given to conduct the approach without a glideslope. You can look at the STL 11-10 chart as a reference.
Where the option to conduct the approach without a glideslope exists, timing is generally provided to locate the MAP, based on timing inbound from the preceding waypoint. Here it's not an option, and therefore only the MAP is listed, and no times.
Nothing at all contradictory about it. No times are provided and only the MAP details are clearly spelled out, to avoid confusion.
What is it that you find contradictory and confusing?
