Touchdown! Greaser!
Are there still airports where NDB is the only choice? I know that was the case about 10 years ago but I don't know about now.
The company I work for was big into NDB approaches when I first started, probably because a lot of the airplanes did not have GPS. In fact, it was specifically in our training authorization that we be both trained and tested on them which sometimes raised eyebrows with the training provider. Nowadays we will see one in training but not so much on the checkride.
There may be a few but they're disappearing fast. One near me just got a nice GPS approach in January.
