Default question on VOR intersections

Anyone know what I'm looking for?


I believe the "National Flight Data Center" (NFDC) is THE source that the
sites mentioned by other posters get their data from (I believe even FAA's
Aeronav gets their raw data from NFDC):

https://nfdc.faa.gov/portal/index.jsp

Click on "FAA Airspace Fix Lookup" which takes you he

https://nfdc.faa.gov/nfdcApps/airportLookup/fixes.jsp

Enter the fix name (or select a state to get a list of all the fixes in
that state.) They should give you the exact latitude/longitude, DME
distances and VOR radials of the fix.

Notice they also have other databases, too, like a "Terrain and Obstacles
Database":

Here's a copy-and-paste of the info for a fix in Oregon called VAUGN which
is a few dozen miles from my house:

Details for Fix: VAUGN

Latitude: 43-57-15.22 N
Longitude: 123-26-57.26 W
Country: UNITED STATES
State: OREGON
ARTCC: ZSE
Fix Type: RP
NAV-FAC-AZIMUTH/DSTC: RBG*VOR/DME*334.81
NAV-FAC-AZIMUTH/DSTC: EUG*VORTAC*204.50/14.00
Updated: 02/16/2006

So the VAUGN fix is 14.00 miles SW of the Eugene Oregon (EUG) VORTAC on
radial 204.5 and NW of the Roseburg Oregon (RBG) VOR/DME on radial 334.81.
Note that only one distance is needed.

Or you can plug in the lat/long values into your simulated GPS.

Thank you, Jim. I'll bookmark these for future use. So far,
the enroute charts have let me do what I wanted.

In fact, it's becoming very apparent why I've seen some folks
push to get an IFR rating. Doing so seems to make navigating
complex airspace such as around LA a lot easier. When you
stick to the 'roads in the sky' and let ATC help you keep
separations, it seems to really enhance the safety and
efficiency of getting from point A to point B.

Default question on VOR intersections

Anyway, what I'm wondering is, is there a resource somewhere
that lists intersections and gives the VOR's and radials that
make them?


Standard aeronautical charts. Visit http://www.skyvector.com to examine charts
online. On charts, intersections that can be located using VORs will have
little arrows that point to the VOR stations that define them.

Say I'm navigating between intersections. I can use the GPS to
fly direct to these positions. However, it seems to me that,
since intersections are exactly that, an intersection of
radials from two or more VOR's, using this information makes
a good backup in case the GPS goes south. Redundancy,
redundancy, and more redundancy.


Quite so. And with a chart you can use VORs to navigate to most intersections.


But looking at the sectional charts, it's not always readily
apparent what the exact radials are. Sure, I could break out
the straight edge and get a rough idea. But I would think that
since their positions are officially defined by someone (FAA?)
there would be a precise definition somewhere.


The radials are always identified somewhere on the chart, typically near the
VOR station itself. Follow the arrows backwards from the intersection to the
reference VORs, and the radials will be marked there.

Is that what you mean?

That's the problem with not having 'real' lessons or experience,
so I don't know how it's done in real life.


You can fly directly from waypoint to waypoint using only VORs, as long as the
waypoints are defined with reference to VORs. It's more tedious with VORs, but
it's certainly possible and practical.

I generally am, but what I've found is I need to intercept the
airway after takeoff, and there's usually a waypoint nearby,
or in a recent case, the airway changes direction at a waypoint.


If you use SkyVector, you can plot a route that will provide you with
headings, radials, etc., that you can follow.

Well, since it is only a sim, expiring charts aren't much of an
issue as the sim will not change. And I have twin 1080p's. I
have downloaded sectionals from the FAA and throw them on the
other monitor. It's no big deal to scroll and zoom a bit. I've
got good graphics editing software.


SkyVector is more practical, in my experience.

For flight simulator programs, there won't be an ATC to give you a
flight plan, so you just wing it.


If you join VATSIM or IVAO, you can get live ATC for the sim.

Actually, the flight sims do have ATC. X-Plane allows me to
file flight plans using anything but SIDs and STARs.


That's nothing compared to VATSIM. Use VATSIM, and you'll have procedures that
are the same as real life, including SIDs and STARs (and voice communication).

BTW, X-Plane is less 'game' and more simulator. It's written
by pilots and aeronautical engineers. The program can be used
to make FAA certified simulators.


That's true for Flight Simulator as well.

I used to peruse this forum years ago. That handle does sound
familiar, and not in a good way, IIRC.
