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.
