Denver Terminal Area Chart Question - BVR vor/dme

Does anybody know why on the Denver Terminal Area Chart, the Byers (BVR
113.5) vor/dme facility is charted without the compass ring that are on most
vortacs? It's the only one I've seen charted like this. Byers is located
33NM on the 090 radial of DVV (the Denver International Vortac).

Thanks, Robert

The presence or absence of the compass rose on a VOR has no meaning.
It is purely at the discretion of the cartographer to omit it when he feels it
would make the chart too cluttered.

We have the same thing on the Cincinnati section for Wright Patterson AFB.
This is only done to relieve some conjestion on the chart.

All right, this makes sense to me. But as someone who is still a student, I
have to ask a question here. Let's say that I'm planning to fly along a
specific VOR radial, and that this radial is not part of an airway. What I
normally do is draw a line on the chart, and then read the radial on this
compass rose. But without the compass rose, how am I supposed to determine
the radial that I need to follow? Most of the VORs in this area have not
been adjusted to keep pace with magnetic variation, and are therefore a few
degrees off from both both the true course and the magnetic course.

I know that I can look up each VORs magnetic variation setting on
airnav.com, but what if that wasn't available?

There might be a better way, but I'd just approximate it by looking at the
VOR's nearby. You won't be more than a few degrees off.

Any airways at all from this VOR? Use your protractor to measure the angle
between the radial defining the charted airway and the line you just drew.

Work out the magnetic course with your plotter and fly that radial. Use pilotage
to adjust your course if necessary. One or two degrees inaccuracy in the VOR isn't
enough to cause any real navigation problems. To put it in perspective, if you
blindly follow a radial and the VOR is 2 degrees off, you will be less than half
a mile off course at the end of 20 miles.

You're supposed to have sufficient reference material (like the AF/D) with
you during your preflight planning. Them's the rules.

Or even better, just drop the plotter on top of the existing airways and
line up the appropriate degree markings with the airways. Then just read
the magnetic course from the drawn course line underneath the plotter. No
need to measure any angles at all.

This will be better than applying the local variation, since VOR radials are
not kept 100% up-to-date with changes in variation. Using existing airway
headings will ensure that the drawn course matches the radio indication,
even if not the magnetic compass.

Compass rings are omitted to reduce clutter on the chart. In this
case, they probably didn't want to superimpose the ring over the big
intersection of Victor airways just to the south.

Here in the Phoenix area we have one without a ring (IWA).
