What is it that will be done away with, the NDBs, the approaches or the ADF kit in the aircraft? Sounds to me that it simply means that there will be no requirement to have a (servicable) ADF fitted to fly IFR in controlled airspace. It would be a shame to loose the NDB network, if nothing else because it is such a great gross error check. I have to say that I have never had the inaccuracies or unserviceabilities experienced by others here and the MDHs I use seem to be about 450' which are still reasonably useful.
