So what level down to does the Adsb signal display on the Brisbane ATC screen? Where is the ADSB outlet located ?
When one of the other of the four aircraft is in cloud and piloted by a 200 hour pilot do you tell him what to do? Or do you allow this low time pilot to decide on what level of safety your passengers will be given?
I understand there is no " standard" for IFR self separation in un controlled airspace!
