Without labouring the "for and against" aspects, I am sure, that in time, ADSB will be an evolutionary benefit to all who require it. My interest is in the subsidy, whether it comes to fruition or not will determine in my mind how, or if, it benefits me and the GA community at large.
To this end I have not seen any recent or positive indication that the corporate end of the Airlines are going to play ball.
Surely it can't be difficult for the pro ADSB enthusiasts to come up with such a document or irrevocable indication on the Airlines part.
