![]() ![]() You need to turn right (fly away from the needle) to get back on course for this localizer back course approach. In the image below, and CDI is set up for the Localizer Back Course approach to runway 17R in KGFK (174 degree final approach course). If you're in this situation, try saying out loud "fly away from the needle." When you're established on the LOC BC approach, you will always "reverse sense" using a CDI with OBS. However, it's easier for many pilots to dial the final approach course with the OBS to remember which general direction they're flying the approach. It doesn't matter whether you select the front course or the back course with the OBS knob (in the image below, 174 degrees or 354 degrees, or any OBS setting for that matter), the needle will work the same. This 'flying away from the needle' is also required when flying outbound on the front course of the localizer." According to the AIM, "when flying inbound on the back course it is necessary to steer the aircraft in the direction opposite the needle deflection when making corrections from off-course to on-course. How To Set Up A "LOC BC" (Without HSI)įor pilots flying a LOC BC approach using a course deviation indicator (CDI) with an omni bearing selector (OBS), you must pay close attention to "reverse sensing" associated with the back course. As stated in the FAA's AIM, "do not use back course signals for approach unless a back course approach procedure is published for that particular runway and the approach is authorized by ATC." If an approach isn't published, you're putting yourself at risk for losing safe separation with terrain and obstacles. Why is ADE Telling me it Can't Compile to the Compile To Folder?
