> Let your would-be-rescuers know your position and status
Stupid question, do search and rescue services even have equipment that can tune into HAM frequencies, are they even listening on those frequencies, and do they regularly train on communicating with the HAM community?
I'm sure there are more established ways of radioing for help in the maritime world(Aviation has the guard frequency)
Instead, can we implement autonomous formation flying? Each aircraft can still have its own engines and control, but can make a V shape allowing the following planes to run more efficiently.
