As you say, part 95 governs IFR altitudes - not tracking airways. It does
not define airways nor how to track them. It defines altitudes to be used
when on and off airways.

Part 95 is irrelevant to the discussion at hand. There are no regulations
that prohibit the use of a non-certified GPS in IFR flight.

Part 95 is what? Regulatory? I agree.

Part 95 talks about altitudes, not tracking airways. Part 95 talks about
altitudes in Alaska. Not the lower 48.

You don't understand how Part 95 works.

Part 95 governs IFR Altitudes in all 50 states and other areas under FAA
jurisdiction, not just Alaska. Where did you get the idea it covers only
Alaska?

IFR Alitudes = MEAs, MRAs, MOCAs, MCAs. Those are the altitudes of
airways. Airways are issued under Part 95 via the federal register via
incorporation by reference, exactly like instrument approach procedures
(Part 97).

The *regulatory* source document for an airway specifies the required VOR
stations, among other things.

The analogy is a VOR approach at PDQ Airport. You cannot fly that
approach using ADF, for example.
