Updated Affected Software Versions
All GI 275 products with software versions 2.21 and earlier, with an HSI page and interfaced to a GTN or GNS series unit are affected.
When the localizer is tuned and a GPS flight plan is loaded, the GI 275 provides a distance to the tuned localizer station. It does not provide a distance to the DME station.
For DME distance, use a receiver capable of providing DME station distances. If the aircraft is not equipped with a DME receiver, use the GPS waypoint distance provided by the navigator.
The distance to the tuned localizer station will be removed in a future software release.
