NACO plates are not to scale outside of the 10-mile ring. Having the dashed
lines enables them to show you fixes that would normally be too far away to
print.

I have a question regarding the rings shown on some charts and not
others. They are a dashed ring and are labeled "FEEDER FACILITIES" and/or
"ENROUTE FACILITIES". The may not be on all charts nor both on the same
chart. For example http://naco.faa.gov/d-tpp/0801/06000LD15.PDF.
I tried the Google route and that didn't work. I thought some of the ATC
folks could help me find out their meaning.
