Why not use a VOR receiver for airway navigation? Using a GPS for
airway navigation kind of seems backwards.

Have you tried it? Putting a flightplan in the GPS and then flying the
line on the moving map eliminates having to worry about crosswind
correction. None of this flying a heading for awhile and seeing how that
works. Then
adjusting that heading constantly for constantly changing conditions.
With a GPS you don't need a DG to fly an airway.

Unless you're happy with S turning your way along, this is only true if
you've the GPS providing track information. A 172S I used to fly had an
MFD plugged into the GPS. It provided not just the flight plan on the map,
but also a line indicating the path the flight would take if no changes
were made. Put that line over the course line, and details like heading,
deviation, and such become pretty trivial.

Alternatively, just match desired track with actual track (starting from a
zero OBS deflection, of course {8^).

That damned MFD really spoiled me, in fact. I was S turning for a while
when I stopped flying that airplane laugh.

On the 430s I fly now, there are only four fields in which information can
be displayed. I use "next waypoint", distance to next waypoint", "desired
track", and "ground speed". I had to give up "actual track", sadly.
