Beyond stupid.

I can use a cruddy old ADF receiver that was manufactured in the stone
age and provides no distance information with a highly innacurate
signal and questionable reliability, but the FAA won't "allow" the use
of a certified GPS.

My Garmin Street Map GPS beats an ADF hands down.


Your Garmin Street Map is just as accurate as a Garmin 500. It doesn't
have the integrity that 500 has, though.

How much integrity does an ADF have? I'll take an non-RAIM-ified
purple line over "it's still beeping" any day.
