There is no way I and others will allow the removal of the en-route SSR network until the ADSB system is totally operational and proven.This will then throw the "subsidy" figures on the scrap heap!
Dick, ADS-B has already been proven. The trial at Bundaberg (or thereabouts) led to the approval of 5nm lateral separation standard using ADS-B alone.
The only reason the standard is not being applied with other ground stations is a lack of comms infrastructure.
Now you're just being obstructionist.
