I see ADS-B in USA was implemented for one purpose, and one only - enhancing air safety.
Then along comes a company that sends out landing charges bills on behalf of airports.
And - as far as I read - admits using the free to air ADS-B data for their billing purposes.
Many have complained to FAA about the misuse of the ADS-B signals for non air safety commercial gain.
Then we go to fitment to "all" VFR aircraft.
In my small single seat aircraft - it physically has nowhere to instal a transponder/ADS-B/GPS. I don't really know how big all that stuff is (is it one thing or three?) but I do know, I don't physically have a place for any of it.
And yes, I have sent that in my submission.
