The FAA is marching toward sole dependence on GPS.

This is recent. Seems like re-inventing the wheel, because FreeFlight, Inc.,
(the old Trimble folks) flight-tested a combination GPS-eLoran a couple of
years ago, providing ground tracks that were virtually indistinguishable.
The maritime industry is using eLoran right now.

That presentation is close to 4 years old.

This has not been discussed as a possible RNP sensor by the PARC
(Performance-based Operations Aviation Rulemaking Committee) during the
past 3 years.

Because RNP is technically sensor-independent an airframe OEM or avionics
vendor is free to attempt to certify any sensor.

Well, let me put it this way. It isn't in any of the FAA's NexGen
performance-based nav systems plans.

No, Sam....LEGACY loran sucks. Enhanced loran (which will require new
receivers/antennas to utilize its GPS-equivalent accuracy) is right
around the corner. A new eLoran station has recently been put on the
air in the UK, and the Coast Guard is well on the way to upgrading its
whole system. Go to www.loran.org and start following links.
www.crossrate.com is another useful site.

And LORAN sucks and does not work in much of the world.
