I agree with you re ADSB, I believe it must be implimented together. I must stress, this is not the current AOPA Board position although I have put it to them.
AOPA have however triumphed ADSB to the minister and ask it be implimented ASAP as a free fit for all of GA.
The slash and burn seems to me to be a reaction to underhanded scaremongering by the ATC and 'little pilot' unions. If someone tells porkies then obviously NASIG is going to push harder and faster before the poo flung from the ramparts starts to stick.
They certainly convinced me they were a pack of turkeys not to be listenbed to!!
