As time progresses, STAR arrival procedures may become more common during normal hours and events on the expert server? so education will be key to the success of the controlling team.
ATC will organize arriving traffic in three dimensions. They’re managing altitude, lateral path, and airspeed to keep traffic separated. Arrivals help with all three. The pilots will simply follow the STAR.
In the last event featuring STARs, “resume own navigation” was used to allow the aircraft to follow the arrival procedure on their own once they joined the STAR.
Once the aircraft received “resume own navigation” they then would follow the STAR and the controller would deviate off if necessary.
This procedure may evolve and change over time so continue to watch, read and listen.
