Finally..., a question where I agree with you Mr F. Binghi !
I think that ADSB is terrific., and I'm really hoping for aural and visual ADSB-IN.,
but without a subsidy (or total reimbursement), it could be quite some time before I accumulate enough money to cover the costs of the gear and installation (I do not borrow money).
Without a subsidy, aircraft hire rates will increase. (no sane GA owner is simply going to write-off approximately $15k)
So., that is one reason why I want to know just what the bleep is happening.
