Here we are, 13 years later, and apparently little has changed.
We've got a navigation system (GPS) that is accurate to within a
meter, and yet the entire system is still built around VORs, which is
accurate to within...a lot. (Anyone know how accurate it is to be
flying a VOR radial say, 30 miles from the VOR station? Is it a
mile? A half mile? 1000 feet? I have no idea...)

I suggest it's a case of accepting bothersome but known and
well-quantified risks rather than accepting unknown and unquantified
risks. The behavior of VORs is well understood; the potential
problems with GPS are not.

But I do know this: In the real world of (relatively unregulated) VFR
flying, GPS rules. The fact that the IFR system hasn't completed the
change-over in a decade is just another example of how glacial
progress can be in aviation.

In IFR, your life depends on the instruments;

You are an idiot.


You don't fly,

Your life doesn't depend on instruments you lying sack of ****.
