RPTR NOTES THAT THE MSP RWY 30L ILS USES AN IAF IDENT WITH THE SAME IDENT AS A DECOMMISSIONED NDB THAT WAS LOCATED 1 PT 1 DME DIFFERENT AND THE CHANGE IS CONFUSING PLTS.

Narrative

THE MOST RECENT REVISION TO THE ILS RWY 30L CHART AT MSP HAS BEEN VERY CONFUSING FOR PLTS. LET ME EXPLAIN. THE OLD CHART (DATED AUG/26/05; AMENDMENT 43A) HAS NARCO AS THE FAF AT 5.7 DME; CO-LOCATED WITH THE NARCO NDB AND OM. THE NEW CHART (DATED OCT/21/05; AMENDMENT 44A) HAS NARCO AS THE FAF AT 6.8 DME. THE OM AND THE NDB ARE NO LONGER PART OF THE PROC. THE CONFUSING PART OCCURRED BECAUSE THE OLD NDB AND THE NEW FAF ARE BOTH NAMED NARCO. THE CONFUSION COULD HAVE BEEN MITIGATED IF THE NEW FAF HAD A DIFFERENT NAME OTHER THAN THE OLD NDB. I INSTRUCT IN THE FULL MOTION SIMULATORS AT A MAJOR AIRLINE. I HAVE OBSERVED THE PLTS BECOMING CONFUSED AFTER FLYING THE ACTUAL APCH IN THE SIMULATOR. WE HAVE DISCUSSED THE CONFUSION; AND CAME TO THE CONCLUSION THAT IF THE NEW APCH FIX HAD A DIFFERENT NAME THERE WOULD BE LESS UNCERTAINTY. CHANGING THE NARCO NAME NOW WOULD ONLY CAUSE MORE MISUNDERSTANDING. HOWEVER; TO AVOID FURTHER SAFETY ISSUES IN THE FUTURE; OLD INTXN NAMES (ESPECIALLY THOSE LOCATED WITH AN NDB) SHOULD NOT BE USED ON ANY REDESIGNED APCH TO AVOID CONFUSION AT OTHER ARPTS.
