Have you ever flown a Loran containing an aviation database? If your
experience with Loran is limited to a device which "only gives latitude and
longitude" then I could understand your concern.

My Loran has a full database of airports, NDBs, VORs, and intersections.
Its output is in bearing, distance, and course deviation, just like a GPS.
It shows me bearing and distance to nearest airports or nearest navaids,
just like a GPS. Operation of the M1 Loran is basically identical to the
IFR-approved M3 GPS except that the Loran does not have a database of
approaches. While the accuracy of the GPS certainly is better than the
Loran, the difference in accuracy is not even perceptible to most pilots in
a practical sense, even comparing Loran and GPS output side by side. While
a GPS certainly is preferable overall to a Loran, I would rather have one of
each than 2 GPS boxes or 2 Loran boxes.
