You could have fooled me.
The noisest proponents tried to sell it here for traffic separation in the circuit at Oodnadatta- a SAR tool- in flight collision avoidance- real time weather and data, all at a give away government funded price = $NIL.
That fizzled out to everyone having to fund their own, if and when, it was mandated. Light aircraft of every description included.
It was and remains primarily a ATC surveillance tool. In that role it does a fine job and is a natural evolution of radar where radar is used for that purpose.
It is interesting to note the "spin" being seen for what is was with the "Capstone" project. Misleading indeed!
