question on VOR intersections

First off, I'm a sim enthusiast. But I try to make my sim
flying as realistic as possible. Besides, getting my ticket
is still on my to-do list... some day.

Lately I've been practicing navigation. It's too easy in
a 747 with an FMS computer, so I'm putting around in a 172
and getting around with VOR's and ADF's. Add some clouds...
at night... weeeeeeee

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

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.

I've googled and looked on the FAA website, but either it
doesn't exist, or I don't know the right search terms.

Anyone know what I'm looking for?

If your program has access to the IFR Enroute Low Altitude charts, all of
the intersections are shown and defined with arrows from the VORs which
define them, DME fixes, etc. as well as Minimum Reception Altitudes (MRA)
and Minimum Crossing Altitudes (MCA). Incidentally, an intersection can be
defined with one radial and a DME fix.

Probably the reason for not showing all of this on VFR charts is clutter and
the fact that VFR pilots will not be needing all of these intersections.

If you are interested in looking at these go to the FAA site:

http://aeronav.faa.gov/index.asp?xml...rtlist_enroute

Click on the bottom on IFR Enroute Aeronautical Charts and that will lead
you to a page where you can download the individual charts. Near the top of
that page is a link to show you a map of the US and location of the charts.
It appears they are in .pdf format, which is strange since most gov charts
are the traditional .tif format with coordinates embedded in the file.
Anyway you can easily look at the .pdf charts.

It only has rudimentary charts, but all the basic info is accurate.

BTW, I use X-Plane, which just released version 10. Much more accurate
flight model. What's sad is I can pull off a CAT-III approach in a
777 about as easy as I can stay on course in a 172.... sheesh.

I can 'fly', but I know in the real world you can't always 'just fly'
anywhere you want.


If you are interested in looking at these go to the FAA site:

I've snagged regular sectionals already. I'll go snag these, too.

tif...pdf... doesn't matter to me. the tiffs are probably geotiffs
for use in GIS software.... which I have too. Another interest of mine
is maps and related stuff. Was doing "Google Earth" type stuff before
Google Earth existed.

www.skyvector.com has the sectionals, WACs, instrument charts and a
neat little mouseover for all airports that report weather with the
latest METAR and TAF.

Now that could be useful. X-Plane can already download real time
weather from the net and configure the sim accordingly.

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.
