MEM CTLR EXPRESSED CONCERN REGARDING IMPLEMENTATION OF NEW RNAV STAR PROCS THAT WERE NOT BRIEFED.

Narrative

YESTERDAY; I RECEIVED A 'STAND-UP BRIEFING' RELATING TO THE NEW RNAV STARS THAT WERE PUBLISHED IN THE RECENT CHART UPDATE. THESE STARS WENT INTO EFFECT WITHOUT ANY DISCUSSION; BRIEFING OR TRAINING RELATING TO THEIR USE AND IMPACT UPON OUR AIRSPACE; PROCS AND OP. I WAS TOLD THAT THE RNAV STARS 'WILL NOT BE USED;' BUT THAT THE ACR COMMUNITY HAS BEEN 'ENCOURAGED TO FILE THE RTES TO SEE WHAT WILL HAPPEN.' AFTER EXAMINING THE NEW RNAV STAR; I HAVE THE FOLLOWING CONCERNS: 1) MEM TRACON DOES NOT USE PAPER FLT PROGRESS STRIPS DURING THE ARR PUSH. ARR E (ARE) AND ARR W (ARW) WILL HAVE NO WAY OF KNOWING WHICH TYPE OF STAR AN ACFT HAS BEEN CLRED TO FLY BY ZME. 2) THE RNAV STAR TERMINATION POINTS ARE DIFFERENT FROM THE EXISTING STARS THAT ARE IN USE AT MEM. CTLRS WILL HAVE NO WAY OF KNOWING OR EXPECTING WHAT AN ACFT WILL DO AFTER CERTAIN FIXES ARE PASSED ON THE STAR. 3) THE HDGS ON THE RNAV STAR ARE ALL DIFFERENT AFTER PASSING BOWEN; CLARK; OLIVV AND TWIKL INTXNS. DURING STRONG XWIND CONDITIONS; ACFT CLRED VIA THE RNAV STAR WILL BE CTRED ON THE DOWNWIND; WHILE ACFT THAT HAVE BEEN CLRED ON THE EXISTING STAR WILL DRIFT TOWARD OR AWAY FROM THE DOWNWIND. THIS WILL ULTIMATELY LEAD TO AN INCONSISTENT DOWNWIND; AND MANY QUESTIONS BY THE FINAL W (ARF) AND FINAL E (ARM) AS TO WHAT RTE OR HDG EACH ACFT IS FLYING. 4) THE RNAV STAR TERMINATION FIXES ARE NOT POSTED ON OUR STARS VIDEO MAP DISPLAY. THESE FIXES ARE CADER; EYEBU; ACALE AND NDREA. CTLRS WILL NOT KNOW EXACTLY WHERE THE RNAV STAR TERMINATES.
