When I was a training captain in a big airline back in the 1980s, there was a move to 'streamline' simulator exercises. One of the items it was suggested we should remove was the NDB approach on three engines in a cross wind. Why, we were asked, should this be retained in the six-monthly refresher training cycle when all the airports to which we operated our 747s were equipped with ILS? We kept this exercise in for two reasons; (1) some alternate airfields were equipped with NDBs (no VORs or ILS) and in the event of a diversion to one of these it was likely the reason for the diversion might be some kind of technical problem. (2) Flying an NDB only approach with an outboard engine failed and in a cross wind was as good a test of handflying ability as you were likely to find.
So I am with you Centaurus.
