I understand the reservations of those who find the reliability of
these things to be less than perfect. But it is a tool and it can be
used, just like ded reckoning. Don't ignore it if you have one.

I had to do a partial panel NDB approach on my check ride (nearly ten
years ago). It wasn't pretty, but I passed. I suppose had I been
taking this exam in an earlier technological day and age, I'd be
extolling the virtues of AN radio ranges. However, I wouldn't doubt
that some day, someone will decry partial panel VOR approaches as
something they would never use.

And despite the existence of an approach certified GPS on our
airplane, I still check my fixes against the ADF when the opportunity
presents itself. Never become too reliant on any one piece of
equipment if you can help it.
