I'm getting close to the IFR checkride and have a question on localizer approaches. We're taught during IFR training that if the glideslope fails while on the ILS, the approach reverts to a localizer approach, and we use the appropriate MDA on the chart, in lieu of the ILS DH.
My question is this-what if an approach is printed as an ILS approach only? Consider the ILS Rwy 26 into Astoria, Oregon (http://www.airnav.com/airport/KAST). The upper right hand corner indicates that the approach is "ILS RWY 26" as opposed to "ILS/LOC RWY 26." There is no MDA for a loc approach, no time table, and no indication of where the missed approach point would be (if we couldn't identify it by the DH). If the glideslope fails, we immediately go missed? How would we identify the missed approach point if that happened?
