Is a APRS (Automatic Postition Reporting System) enabled ham radio a
reasonable substitute?

Probably not for SAR since PLT's work fine BUT what a great idea for team
flying.

I note that Winpilot can plot team members position on the moving map
display. Link members of the team with APRS and feed the data to Winpilot
and each could see the position of the others.
