Rivet Arrival Sydney
I would appreciate any help any ATCers or pilots could give regarding how to handle the Rivet Arrival into Sydney, Australia. Our crews on our FMS airplanes have been given vectors off the Rivet, then back on, then back off, and numerous speed restrictions and then instructed to "resume the Rivet arrival." On occasion we are left hanging too high and too fast to get below 10,000 feet in time to slow and then meet the Tammi restriction at or below 9,000 feet. If we could publish an altitude/speed "gate" along the way above 9,000 feet prior to Rivet it might help us put the airplane in position to make the restriction at Tammi. Many thanks for your help.
