Chief Galah,
I apologise. Indeed it is. The others aren't and directly from the project manager I've been told that it's unlikely that they will be. There is a problem with data transfer delays at other than YMEN that render them invalid for separation services. I take a contrary view that they are still useable for limited services such as establishing outside latsep points and opposite direction passing. The error would always be on the safe side. This is being investigated.
