I have just read, an announcement released today by AsA and mentioning Greg Russell's statement that ADSB is to be introduced into WA on a trial basis for the mining industry flights.
And now, my 'oletimers' has set in and I can't find it for posting here.
It concluded with the explanation that the communications network had to be converted from analogue to digital - and apparently nobody recognised the scope of work required to do this - hence the delay.
I thought I saw it on the RAA site - but ........
I'll go quietly....
