Fuji. That's of course the whole point. Fixed in your mind is that because some 1950s unique Australian rule ( probably industrially driven) requires a terminal rating to provide a control service at a non tower airport then we must never change and follow more modern procedures from other leading aviation countries.
Get with it. Get your Union to put the safety of air passengers in front of keeping 1950s practices!
WAM is supposed to be so accurate it can be used to accurately position aircraft on taxiways so why don't you move to get it to be used properly in the terminal area in Australia? Or is that an industrial issue as well?
Am I on to you?
