Howabout
WAAS is not needed for ADSB, here or anywhere else.
WAAS really gives big gains in Vertical accuracy, ADSB uses the Altitude Encoder like you have now in your Mode C set up.
ADSB does not have or warrant the WAAS vertical accuracy any more so than radar and Mode C.
WAAS is needed for making a NPA into a PA, so the ILS type of accuracy and Minima that the yanks have on GPS approaches.
Australia would also benefit from WAAS.
Regionals would greatly benefit and the big three also at regional aerodromes. As an example a few weeks back while battling VFR around low cloud, mist and light rain, I could here the Sunstate guys and girls having several misses at Roma, Charleville, Blackall and so on. A week before Jetstar and Virgin were having the same trouble at Hervey Bay, and I think Sunnies at Bundy as well. Maroochydore was also having the same trouble.
WAAS is another thing of the future with BIG safety gains and efficiency gains, when the weather is not so good.
And if anyone can..... they should push it ant any opportunity.
