Whats the story with the Garmin TAS - me-hears that some Garmin GPS can talk to each other, and give an 'INs' traffic for nearby aircraft ? ...does this mean we dont 'need' ADS-B ? ....
really
Bing ... and how would that occur .....
As regards scale (distance) it is as I said scaled based on speed and closing .. what part of that do you not understand??? .. the example given might be indicative of enroute flight!!
In a GAAP CTR, (as one example) whilst on base you might get a traffic alert on opposite base traffic if you are possibly/likely to swap paint!
......of course theres little profit to others if a Garmin portable can give 'INs'
little profit for who? in any of it? ... or is the real motive introspective
you that is ... ***** corp anyone?!
