Yet they manage it at busy airports in the USA
And, as always, folks, there is a reason --- FAA have to provide services to all-comers, they cannot deliberately exclude you because you are a lighty on a sightseeing flight --- and there is simply no equivalent of the Australian "culture" of "screw you, there is nothing you can do about it" which is all to pervasive in Australian ATC.
Yet, if you said to the average Australia ---- you and your car are barred from the roads if there are trucks and buses about, there would be hell to pay ---- ain't democracy wonderful!!
With the obvious exceptions of Presidential flights, medivacs and emergencies, everybody else in US has the same priority or, more correctly, there is no ATC priority system.
Tootle pip!!
