LS, I completely understand where you are coming from, but I'd be quite surprised (especially in the case of NAIPS falling over) that if CASA tried to ping one and send said accused-dodgy-bastard in front of a judge, that the judge would convict.
The BOM website states that they are the provider for ASA. ASA, "the provider", also states in their own documentation (AIP) that the BOM supplies them. If we cannot get and use information from the provider's provider, then that's a crock.
Another thing that would surprise me is if the BOM would actually publish "unapproved" data in their specific Aviation section; that would leave them fairly open.
The term "equivalent level of safety" comes to mind.
You've stated that there have been prosecutions in this regard. Is that available for online reading and can you provide the link? I'd be interested in reading them.
Going on a tangent here, isn't the BOM responsible for the AWIS sites? They are "approved" bits of info when we tune in or phone them up and it doesn't come via ASA.
