I read them as part of my normal Notam check (via NotamPlot). If they are in the system I see them. Do they come up as standard? Similarly, I have always assumed that the Reds were included in the standard Notams; please tell me this is true.
I don't use NotamPlot so I can't comment on how they are handled by it. However the data is there as standard in the brief from the AIS site, and yes the Reds also appear as do any other RA(T). The 0500 number mentioned above also covers all temporary airspace restrictions and upgrades so they'll be there as well.
The use of significant points that don't appear on the CAA's VFR chart in NOTAM scoped for VFR is something I've brought up previously with my AOPA hat on at meetings with the CAA. In the example I posted above it's pretty clear where the restriction is (LYNEHAM CTR EXTENDED 6NM EAST ) but that's not always the case. I've now brought this point to the attention of Phil Roberts, who is Assistant Director of Airspace Policy 1 at the CAA and also chairs the DAP Airspace Infringement Working Group. He's looking into it and has promised to come back to me.
