ADSB is the answer
Hmm
From the guys at the Belgrano, ADSB isn't the clever solution that many believe. Although who trusts the Belgrano.....
We were told that ADSB would be a future option, but would depend on 'an approved GPS', so that rules out Garmin196 etc/Skymap IIIc etc, so will mean even more expense - a Mode S + an approved GPS
