Which just goes to show that it all depends on what sort of operation you are employed on. In my world, NDB approaches exist, but if we use them, it's very rare and we wouldn't do it unless the FMC says that it's accuracy is 'HIGH', probably derived from the GPS element of the Multi Mode Receiver. So it essence, it's a RNAV approach. In fact, if there isn't an RNAV overlay published for the approach we wouldn't be doing it as the approach wouldn't be in the FMC database. We have to have the needle displayed, but it could just be the head of the needle superimposed on the NAV display. Essentially, we are doing the approach onto a position which happens to have the beacon there and for which there is a published procedure. It's effectively no different to the GPS/RNAV approaches we do into some of our destinations.


And on the Airbus, we would probably fly a 'Managed Approach' which to all intents and purposes is very similar to a Flight Directed ILS. It's very easy - and very safe. Which in this day and age is what air transport is all about.
