I think it's a bit rough to expect ASA to keep track on Jepps to make sure their documents marry to the official line (AIP)......surely thats Jepps job?
My understanding is that it is CASA that approves Jepp (and others) to re-publish AsA stuff, so CASA should be oversighting Jepp.

I like it. Make it happen!
