Ummm Dick, the time for commenting on that JCP has long passed.(31OCT07) was the reply date)
The transition from the old system to TAAATS didn't happen overnight so why would ADS-B be any different. AirServices is going to have a tleast six years of data on how the system works BEFORE any ADS-B transition starts today plus 4 years time. The last SSR will be decommissioned six years after that time.
Dick I am sure you read pageiii of the intro of the JCP-
Should the proposal not be adopted or be delayed. It will be necessary to begin replacing existing ground-based systems at the end of their life. It is likely that this would reduce the funding available to assist light aircraft to transition, and erode the operational and commercial benefits offered by transition to satellite technolgy
Is this your aim, Mr Smith?
