I normally observe that aircraft passing out of ADS-B coverage in AU are shown with ‘ATC Radar’ tag where they are in coverage of AU ATC radar.
Today 1Aug14 that is not happening (we are one day ahead of the forum date here in Australia) -
All aircraft not within FA ABS-B coverage are showing ‘ESTIMATED’ The result is quite poor accuracy.
Is there an issue - or is FA no-longer getting AU ATC Radar?
If someone from FA needs more details they can email me on the address in my account.
