The Avidyne TAS unit is self contained within the aircraft, and it reads other aircraft that have transponders - and those transponders are self contained within the aircraft. If the ATC system and/or the GPS system became inoperable for any reason what so-ever, the TAS unit in my aircraft will continue to show those transponder equiped aircraft.
Ever wondered how many in the circuit area do not have Mode C ?
Now as you have your fancy TAS unit and see 3 or 4 a/c ahead, you feel all waarm and fuzzy and make your calls and circuit.........only to discover there are 2 x Tiger Moths doing slow formations, 2 x RAA Jabirus, 1 x RAA Drifter and 3 gliders......ALL in the circuit
.
I am not a big fan of ADSB IN for PVT GA, however if you are going to have it you really need to be sure you are capturing ALL the info. Much less than all is more likely to be dangerous.
And the day when the GPS is off for 30 min...... you might have to revert to MK 1 EYEBALLS
