On TIS:
I dont really understand why ASA dont send the information they get from their radar out on the ADSB Path. That way people could see both ADSB and normal transponders on there displays even when other aircraft are not ADSB equipped.
Hell they send this data out to some Aircraft noise lobby group. You can get it on a web site. Surely it's not hard to feed that same info into the ADSB. Then I guess that would not be in line to forcing people to get the new units.
Smells like politics.
