Just read the article in the Oct Nov Air and Space....Lost in America.
And Oz.
For a private aircraft full ADS B benefits come a great cost.. and is no guarantee in remote no signal / blocked signal areas that you'll be found if you crash out. "ADS-B...is not meant to hunt for missing a/c"
On the other hand, "breadcrumb" GPS tracking via satellite knows where you at all times...
And with GPS positioned aircraft symbol on yr moving map flight screen..any prob with a position report?.
I know where my $$s would be spent.
