BOAC, I couldn't agree more, the Radalt provides another layer of SA that is often missed. It is only useful if it is adequately briefed beforehand. I seem to remember that many high energy approaches stem from those approaches flown over high ground descending to the runway. (ILS 19L+R into Oslo?)
Sadly, in this case, the obvious SA cues were missed. There are those who have done it and those that are going to!
