Threads like this serve little purpose, except to enable the bashing of certain groups by the self proclaimed elite intelligentsia and serve as a platform for more sales spiels about anti collision and surveillance devices by the agenda driven and rabid collaborators.
If you are concerned about non radio or non transponder equipped aircraft in class G airspace, don’t fly IFR there if you aren’t going to look out the window. Some of you would crash through a marked glider and parachute areas and complain about gliders and parachutes.
Fly IFR in class G airspace but remember it’s not mandatory for VFR traffic to fly with a radio or transponder, so if you are aware of this fact and accept you may run across a ‘cowboy’ in this flight regime, be aware and don’t expect what is an optional extra to be mandated because it makes you feel safe.
It’s easy to bag any pilot with poor radio procedure at a CTAF but remember it’s better than him not calling at all. In many cases he is not required to do so. Accept that alerted see and avoid is better than see and avoid.
Do you really believe that the entire RAA fleet of 3000 can be simultaneously airborne, flying at your altitude or in your immediate vicinity? Divide the total surface area of Australia by the RAA register and see how many aircraft per sq mile there are. Then think three dimensionally.
Ultralights don’t fly IFR and most can’t fly in the rain because of untreated fabric wooden propellers and so forth, many haven’t the grunt to get above 5,000ft.
It stands to reason that no VFR traffic would be airborne in IFR conditions.
In VFR conditions it is your responsibility to look out the window.
