Dick I think it is a serious case of lack of situational awareness by ASA and CASA. They don't seem to recognize that aviation wise we are a pissant country with relatively few aircraft and a huge area of land.
If it is shown that the early introduction of ATSB is nothing more than ego driven skiting then they should be sued in a class action for the difference in price of ADSB equipment in 2017 and the price when it is mandated in the US.
Their arrogance is breathtaking . Forcing Australians to buy ridiculously expensive equipment now when we know that in a few years it will be a fraction of the current price is nothing short of criminal.
CASA and ASA should have to present a cost/ benefit analysis showing why although we coped all these years without ADSB suddenly we can't cope a few more years until the price becomes affordable.
