Standard Terminal Arrival Route. If you select Dep/Arr on the FMS, select the arrival airport, then the runway and approach in use, you will have the options of the several STARs available. You can usually guess which one is likely, and this will be confirmed later by ATC. It will then automatically load the full route to landing, obeying all height and speed restrictions automatically. You can simply confirm from the chart that all restrictions are correctly loaded, then automatically fly the profile, eventually to be peeled off on radar headings to suit ATC.
