ACARSd the new ADL TAF to the crew around TOC out of Sydney
But what happened after that? What happened to the active operational control? Was there no communication about where they would divert to? If the crew advised FD that they would continue and use MIA as a back up what monitoring of the weather situation did FD have? I don't think that its as straightforward as simply acarsing ( a new verb!) an updated TAF.
