This is a procedural error on your part.You should not select APP mode for a localizer approach, either back course or front course. You should instead select NAV mode to enable lateral guidance only.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Washington, DC

Also, when you fly the BC, you still must dial the FRONT course into the course select window. Otherwise you will get reverse sensing of the localizer.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Washington, DC
