Tied Down
That doesn't work, both the BARR request (which all my planes have been on, even at the source level) or the call sign, if you have ADSB or mode S, you're transmitting in the clear to any azzhat with a antenna, give me a blocked tailnumber and I'll tell you where it's been.
Doesn't even have to be an "azzhat". LOL. People don't get this part, but we keep saying it...
It's an insecure data system transmitting a number that directly correlates to a tail number. The receiver costs $25. Places like FlightAware offer the ability to integrate thousands of cheap receivers into their overall picture in near real-time. And do it already.
There is no technological solution to the problem because the system was engineered poorly, even for the era in which it was engineered.
One of the helpful but not perfect answers is to stop sending the aircraft specific ID when squawking VFR, but only one manufacturer's product did/does that and they're taking flack for it from the people who created the insecure, mis-engineered RF data system.
The number used over the air should have continued to be assigned at departure. There's zero safety reason to identify the specific aircraft beyond one flight with the same over the air identifier.
