The correct approach to eliminate reverse sensing during a LOC BC (Localizer Back Course) approach on a Horizontal Situation Indicator (HSI) is by placing the HSI arrow on the reciprocal track of the LOC BC inbound track. This is necessary because the localizer signal for the back course approach provides guidance to the pilot as if they are flying towards the station from the opposite side.

When conducting a BC approach, the HSI will display indications based on the inbound and outbound tracks, but the pilot is actually flying towards the localizer from a direction that is opposite to its intended approach path. Positioning the HSI arrow on the reciprocal track effectively aligns the display with the actual flight path being followed, thereby correcting any reverse sensing errors.

This strategic placement allows the pilot to follow the glide slope and localizer guidance correctly without confusion, ensuring accurate navigation during the approach. It helps in maintaining situational awareness and reduces the risk of navigating incorrectly as a result of reverse sensing cues.
