Problem A:
In my limited experience with sharing untowered CTAF airspace with RPT, the procedure seemed to be that the PNF monitors the CTAF and then established two way comms with me.
.Isn't it possible to mandate a listening watch and enough broadcast calls to preclude an unannounced arrival or departure?
Problem B
I have yet to meet an RPT where we couldn't work out guaranteed separation in about a ten second conversation.
Sunfish,
a practical suggestion and hopefully realistic assessment of the RPT jet jockeys.
However, looking through relevant “separation” incidents in G, there are consistently problems with communications.
Our system should be somewhat human error tolerant, ie that is why IFR traffic info in G is mutual and ATCs transmit info to both aircraft on the basis that a conversation will be initiated by one of the aircraft.
Was there a specifically relevant part of the latest Ballina incident that you identified with Unannounced arrivals or departures?
