Most small a/c are not ALL small a/c and not all are fitted with a Mode C, so when one smacks into an A320/B717/Q400 at a CTAF R with no Radar coverage, ask the victims relatives about what the benefit would be.
A small ADSB out is not a real impost on us, and it has some other benefits aprt from a bigger bird running into us.
ADSB is the future......... some just have not seen it yet.
Mr Radar salesman would of course disagree 100%
