BUT.. in the way you propose to use, APRS involves you being recognized
as overdue by someone, and them initiating the search by reporting an
overdue aircraft and giving the last known coords.

Or do you think that filing a VFR flight plan with your own personal
findu.com emulation page address would suffice?

An impact activated ELT at least lets SOMEONE know you are down.
Particularly a 406 mhz one, since it broadcasts last known position as
part of its data burst.


I've not used APRS in the air, but I do realize its fairly easy to rig
up with a little handheld portable and tinytrack three, and the setup
can take a data feed from ANY NMEA gps, such as any of the portable
Garmins (aviation or not). On the ground, I use a APRS ready Mobile with
a GPS3 feeding it.
