Narrative:
I was taxiing onto runway 28 at agc for takeoff. The runway was covered in a couple of inches of snow; and the visibility was 1/2 mi. All runway markings were obscured. Our company procedures dictate tuning in the localizer for all takeoffs. I noticed that the localizer needle for the ILS 28 was displaced approximately 3/4 to the right when I was in position in the middle of the runway. I've also noticed that the ILS 28 localizer does not line up with the runway centerline when conducting visual approachs to land. The displacement is significant. I believe this could potentially be a safety hazard when conducting low visibility takeoffs or lndgs. Perhaps the FAA could conduct a flight test to verify the alignment of the localizer beam; or list a note on the ILS 28 approach plate that the localizer beam is not aligned with the runway centerline. No such note is on the current approach plate.

Title: A PA31 PLT NOTES THAT THE AGC RWY 28 LOC COURSE SIGNAL IS NOT CTRED IN FLT AND ON GND WHEN USING RWY 28 FOR TKOF AND LNDG.
Narrative: I WAS TAXIING ONTO RWY 28 AT AGC FOR TKOF. THE RWY WAS COVERED IN A COUPLE OF INCHES OF SNOW; AND THE VISIBILITY WAS 1/2 MI. ALL RWY MARKINGS WERE OBSCURED. OUR COMPANY PROCS DICTATE TUNING IN THE LOC FOR ALL TKOFS. I NOTICED THAT THE LOC NEEDLE FOR THE ILS 28 WAS DISPLACED APPROX 3/4 TO THE R WHEN I WAS IN POS IN THE MIDDLE OF THE RWY. I'VE ALSO NOTICED THAT THE ILS 28 LOC DOES NOT LINE UP WITH THE RWY CTRLINE WHEN CONDUCTING VISUAL APCHS TO LAND. THE DISPLACEMENT IS SIGNIFICANT. I BELIEVE THIS COULD POTENTIALLY BE A SAFETY HAZARD WHEN CONDUCTING LOW VISIBILITY TKOFS OR LNDGS. PERHAPS THE FAA COULD CONDUCT A FLT TEST TO VERIFY THE ALIGNMENT OF THE LOC BEAM; OR LIST A NOTE ON THE ILS 28 APCH PLATE THAT THE LOC BEAM IS NOT ALIGNED WITH THE RWY CTRLINE. NO SUCH NOTE IS ON THE CURRENT APCH PLATE.
