ADS-B subsidy...I can say heaps on the subject but refuse to.
So much for the misinformation debate.
SC....you do not need another transponder....this isn't the United States.
If ADSB is an evolutionary development of the transponder as a tool for ATC but it can't be interrogated by TCAS, you will need a mode C transponder as well as the ADSB gadgetry for TCAS to work won't you?
