SAR is not going to be able to go directly to the point where you went down.
All they know is when where you started from, where you were going, and how
you were planning to get there. When SAR is initiated 1/2 hour after you
don't arrive, they have the entire route to search. But, at least they have
a route to search. The closer to the center line of that planned route you
are when you go down, the better the odds of them finding you. Lat/long
fixes or formal NAVAID fixes, it doesn't really matter.


For VFR flight plans LAT/LON has a huge advantage over published fixes
in many parts of the Western U.S., both to avoid restricted areas and
remain in valleys (ala Eastern California, most of Nevada, and other
states with similar topography.
