Well Gemma this is supposedly part of the reason why the changes are being brought in.
I think most of us have had this 'higher level' of service. I for one certainly appreciate it. But if you look at the new services you will see a much more legalistic interpretation of the services.
None of this has been helped by past changes and 'advice'. RAS is no longer recommended for VFR flight - but interestingly Deconfliction will be available to VFR. It will be interesting to see if it is actually available.
To be honest I cannot see any ATC person seeing a potential collision deciding to not communicate that fact to the traffic - even though his operating instructions actually prohibit it.
Our local tower has a radar repeater - but their operating instructions prohibit its use for traffic information. They have devised some interesting approaches to work around this!!!
