I was browsing through my log book and as near as I can figure the last time I flew a for real NDB approach in IMC without GPS supplemental track guidance, was 1994
Ever since then I have always broken out of the cloud with the runway at straight ahead and with the track of the aircraft aligned with the runway centerline thanks to the magic of GPS. Thank God for better living through high technology. The ADF is 80 year old technology, there are still ludites that insist it has value but the advantages of modern nav aids are so compelling I can not see how they will not be able to hold on to the ADF requirement much longer. In this area the bean counters are actually out friend as making the case to continue to spend money maintaining NDB's will be harder and harder in this economy.
