. Every IFR pilot (and IFR magazine reader) should be familiar with the term STAR, which stands for Standard Terminal Arrival Route -- published routes designed (as per AIM 9-1-4) to "expedite ATC arrival procedures and to facilitate transition between en route and instrument approach operations." Every pilot -- IFR or VFR -- should know about ATC's STARS. It's not the TRACON's basketball team but, instead, is an approach control tool that means:a. Special Terminal Approach Radar Systemb. Standard Terminal Automation Radar Systemc. Standard Terminal Automation Replacement Systemd. Sequence Tool Air Route Systeme. Standard Tired Automatic Request Squelcher (FAA's "Just Say No" tool)

Jim,I believe there is a waterfall schedule for the STARs systems to be implemented into US towers.
