I've been told there are examiners who will try an ADF marked
INOP while you're flying, and if it works, you get to fly an approach
with it. You need something a bit more drastic. Does it have a fuse
you can remove? Maybe some tissue paper or seran wrap
over the connector blade? You could remove it altogether but then
a finicky examiner will want to see a revised W&B.
I quite like the challenge of flying NDB approaches without
help from the GPS, but I'd have to be very, very desperate to do
it for real. Without a serious crosswind it isn't TOO hard, as
long as you concentrate on BOTH the heading and the ADF.
I prefer to use only the mag compass. My instructor drummed this
into me during my instrument training. I still remember the
heading for the Stockton NDB because he would chant it all
the way down final. As others have said, it does take a LOT
of practice.

I made my first big IFR mistake. I fixed my intermittant ADF with only
a few more hours of training to go until my checkride. My glorious plan
to label it INOP (making it an expensive combination multi-channel timer
and partial panel heading memory aid) has been thwarted by a little tuner
cleaner on the card edge connector and the socket on the tray. A small
part of me was hoping that the aluminum swarf that someone rained down
on it while modifying the panel (which I removed a while ago without
fully fixing the problem) had killed it for good.
Anyone have any good NDB approach tips and tricks?
