Hi,
I've just read this
In December 2009, Air Services Australia commissioned the ADS-B Upper Airspace Project (UAP), providing ADS-B coverage across the whole continent. Since then, 29 duplicated ADS-B sites have been added, plus a further 14 sites in Tasmania which are associated with the now fully operational Tasman wide area multilateration (WAM) system. Aircraft avionics are being assessed and approved for operational use. ADS-B data from non-approved aircraft is filtered out at each site. Currently, over 1200 airframes are approved and receiving the operational and safety benefits of ADS-B services in Australia. Australia has also made ADS-B equipage mandatory for all aircraft (domestic and foreign) operating at or above FL290 as from December 2013.
what I'm wondering is, what difference does it make to how our position information is displayed to you? and what are the 'operational benefits' the 1200 airframes are enjoying?
Cheers
