The best expert I know is Ian Mallet. I talk to him regularly and respect his advice.
He hasn’t yet got the cost benefit figures for the whole of our country. Do you?
Spot on Dick, I knew you would know Ian.
Sorry but I don't have any such figures. All aviation interests need to get going with this, as Ian will tell you, this is our last chance to have SBAS. Ben at AOPA is now onto this as well.
20 years ago Australia was a world leader in GNSS, now we are so far behind due to past governments who did not give a rat's.
