Dick,
When ADSB was first announced, didn't Airservices say that they were going to pay for the unit to be placed in the aircraft as it would save them millions of dollars per year not to run the aging radar hubs?
There was a rolling payment schedule that reduced the amount they would pay depending on how close to the deadline you got the unit fitted!
So are we now expected to pay for a more expensive unit, AND Airservices reap the profits?
Doesn't seem fair.
