Australia certainly seems unusual to me in that they don't have co located DME's on all their ILS's and in some cases don't even have an ILS. That is not 'worlds best practice' or whatever they like to say.
Agree. While not an ILS, the Cairns 33 LLZ is a classic example. A few years ago it was redone, but the DME remained at the other end. Very difficult to use the DME as a quick-check.
DME x 300 works really well for a 3 degree approach on to this runway because of the combination of elevation and DME distance from the threshold.
It's published on the plate anyway.
For this Thai crew, was it? I doubt they use DAP. The
2009 NDB approach chart for that incident had 2 critical mile values missing: 7DME and 6 DME.
