Sticky DG and DME distance question

that they can bring up range rings on their new screens, but if a controller
is busy he/she might just "eyeball" it.

The controller almost always eyeballs it. As for range rings they are
alway displayed and are drawn around the radar site, not around an
individual airplane.

Of what possible use would range rings centered on the radar site be? From
my memory of a visit a few years ago to a TRACON facility, I seem to recall
that the controllers could get a reasonably accurate reading of distance
from given fixes (e.g. VORs, OMs, airfields, etc.) by calling up range rings
from that fix to appear on his/her scope. Given the level of digital
sophistication they have available on the newer technology radar displays,
that would be a piece of cake. Still, as you state, my guess is that most
controllers, particularly experienced ones, usually eyeball it unless more
precision is required.

I have a 70's vintage Mitchell DG (with autopilot bug) that was drifting off
course rather quickly. After snooping around with Google groups to see
which overhaulers had the best reputation, I sent mine off to Ducasse
Aircraft Instrument Service in Pennsylvania for overhaul. It's been working
great for the last 10 months. Expect it to be out of service for about 3
weeks even with air shipping.

Couple of questions.

Went up to practice some ILS approaches. While being vectored for my
approaches, my DG kept sticking through the 270 heading. First time on my
initial approach and the second approach. Third and fourth approaches, DG
acted normal, though seem a little off compared to the magnetic compass.
(gave me good practice for partial panel approaches!).

Also, my header bug seem to be frozen, couldn't move it at all. I ended
up
using my magnetic compass and VFR GPS for my primary navigation and
tracking.

I had this happen once on the ground a long time ago, and never gave any
thought as it performed flawlessly in the air since. Vacuum gauge was
exactly where it should be.

Last thing I want to worry about in the clag is the DG. Is the DG worth
overhauling or just getting a new one???

I went to http://www.aircraftspruce.com/menus/in/gyros.html to see what
prices I am looking at, and it seemed all over the page in price. This
would be a part obviously I don't want to cheap out on, but I don't want
to
buy a part that is has something in it I never will need.

Suggestions much appreciated. I figured to post this time b4 going out on
the limb.

DME question. While on my VOR Alpha approach back to MBO, ATC reported me
3 miles from the VOR, and my DME reported me 4 miles. This is the first
time I ever had a discrepancy that much. Anybody know what gives. My DME
seemed correct as it reflected 5 miles to my airport.
