Narrative:

The NDB approach at pensacola regional airport does not align aircraft with runway 16, as is published. When approach is flown as published, aircraft are consistently displaced 3-5 mi to left (east) of the published final approach course. The NDB and ILS both have a published final approach course of 166 degree. When flying the ILS 16 approach to runway 16, the NDB indicates a magnetic bearing of 156 degree when the localizer centers. This difference of 10 degree is observable in many different aircraft and has been confirmed by other pilots. Recommendation: change the final approach course magnetic bearing for the NDB 16 at pns to 156 degree. This will better align approaching aircraft with the runway centerline, rather than dropping them off at the 600' MDA 1 1/2 mi left (east) of the runway centerline to runway 16.

Title: REPORTER STATES NDB APCH WITH HEADING OF 166 IS MISALIGNED WITH RWY LEFT AT PNS.

Narrative: THE NDB APCH AT PENSACOLA REGIONAL ARPT DOES NOT ALIGN ACFT WITH RWY 16, AS IS PUBLISHED. WHEN APCH IS FLOWN AS PUBLISHED, ACFT ARE CONSISTENTLY DISPLACED 3-5 MI TO LEFT (EAST) OF THE PUBLISHED FINAL APCH COURSE. THE NDB AND ILS BOTH HAVE A PUBLISHED FINAL APCH COURSE OF 166 DEG. WHEN FLYING THE ILS 16 APCH TO RWY 16, THE NDB INDICATES A MAGNETIC BEARING OF 156 DEG WHEN THE LOC CENTERS. THIS DIFFERENCE OF 10 DEG IS OBSERVABLE IN MANY DIFFERENT ACFT AND HAS BEEN CONFIRMED BY OTHER PLTS. RECOMMENDATION: CHANGE THE FINAL APCH COURSE MAGNETIC BEARING FOR THE NDB 16 AT PNS TO 156 DEG. THIS WILL BETTER ALIGN APCHING ACFT WITH THE RWY CENTERLINE, RATHER THAN DROPPING THEM OFF AT THE 600' MDA 1 1/2 MI LEFT (EAST) OF THE RWY CENTERLINE TO RWY 16.
