A-SMGCS in operation at YMML, YSSY with TCAS/transponders going full bore. Obviously no bandwidth issues there. Stop making grandiose, sweeping statements that don't apply everywhere.
While the comments are for operations where there are issues, why do you continue to comment on areas where there are not issues? As noted, IF and WHEN AUS adds ground ops, there will be bandwidth issues, like at other locations where they have.
Again, time to READ, evolve, and stop stalking, stop inserting yourself where you are irrelevant.
Did you figure out that Perth only has one AWOS, and when you get TCH winds, it is simply because they give the winds per runway end with the corresponding headwind/tailwind component? Or do you really think they measure they winds at each TCH?
