A320 Glider
I flew one of our 777s recently and it didn’t have ADF fitted at all, so NDB approaches were off the menu anyway.
RNP approaches are demonstrably safer and usually will have lower minima compared with traditional NPAs = better chance of success. Yes, VOR/NDB are a great skills and CRM exercise in the sim but as they get rarer and rarer on the line, you get to the point where it would be better to stop flying them and use the time available to train something more relevant. The incident/accident statistics on NPAs are not good and it’s getting close to the point we should be calling time on them, now we have a viable (and better) alternative.
