Not quite sure I understand what the big deal is, this is a changing industry, was there a subsidy for installation of TSO GPSs into aircraft or for the removal of the old OZ DME system ?.
Sounds like crying poor to me, if an operator can not absorb the small cost of an ADSB unit how can they possibly afford an unplanned engine or SIDS ?.
Most private aircraft owners will grumble, but do not have closed minds and will see the benefit to such technology and will have ADSB installed next time their transponder makes smoke.
Harden the f*** up.
James, would we be using TERM ADSB at place like Tamworth ?.
