Narrative:

Aircraft consistently track right of the ILS runway 6 localizer and left of the ILS runway 24 localizer. When asked, the pilots always state they are dead center on the locs. A new map was installed showing the new ILS runway 6 localizer but it does not show the ILS runway 6 fixes, it shows the fixes for the old back course runway 6 approach. Several ucrs have been filed as far back as jul/wed/94, on map alignment problems and the answer then as is now is that all will be fixed with the installation of the stars system. If this is done on schedule, which has already slipped numerous times, it will be approximately 7 yrs from the date of the original ucr. Safety is an issue here. Some maps are off 2-3 mi when compared to each other. I can show myself in my airspace when I am actually in someone else's. Is the FAA really going to situation on this safety problem for 7 yrs?

Title: APCH CTLR STATES THAT THE RADAR MAPPING FOR RWYS 6/24 IS OFF AS MUCH AS 2-3 MI. UCRS HAVE BEEN FILED AND NO RESOLUTION HAS BEEN FORTHCOMING.

Narrative: ACFT CONSISTENTLY TRACK R OF THE ILS RWY 6 LOC AND L OF THE ILS RWY 24 LOC. WHEN ASKED, THE PLTS ALWAYS STATE THEY ARE DEAD CTR ON THE LOCS. A NEW MAP WAS INSTALLED SHOWING THE NEW ILS RWY 6 LOC BUT IT DOES NOT SHOW THE ILS RWY 6 FIXES, IT SHOWS THE FIXES FOR THE OLD BACK COURSE RWY 6 APCH. SEVERAL UCRS HAVE BEEN FILED AS FAR BACK AS JUL/WED/94, ON MAP ALIGNMENT PROBS AND THE ANSWER THEN AS IS NOW IS THAT ALL WILL BE FIXED WITH THE INSTALLATION OF THE STARS SYS. IF THIS IS DONE ON SCHEDULE, WHICH HAS ALREADY SLIPPED NUMEROUS TIMES, IT WILL BE APPROX 7 YRS FROM THE DATE OF THE ORIGINAL UCR. SAFETY IS AN ISSUE HERE. SOME MAPS ARE OFF 2-3 MI WHEN COMPARED TO EACH OTHER. I CAN SHOW MYSELF IN MY AIRSPACE WHEN I AM ACTUALLY IN SOMEONE ELSE'S. IS THE FAA REALLY GOING TO SIT ON THIS SAFETY PROB FOR 7 YRS?
