10JQKA - I attended the Class E Webex meeting and the Airservices' participants were only the project staff. The "change" managers, I know their names, were very likely listening in, as was the manager of OAR, but they chose to say nothing even though the whole concept was challenged.
You will find the project people have no power to do anything other than tell you what Airservices is going to do, listen to your replies, and then wait for the managers to tell them what to do. They will not be in a position to discuss alternatives, real or otherwise, and OAR will simply wait until Airservices tells the Minister and the new DAS what they want. The rubber stamp will then be exercised, yet again.
