The FAA provides non-geo-referenced approach plates in pdf format which can be downloaded individually or batch-downloaded and placed on a USB flash drive. This feature was intended for use in Horizon HXr or multi-screen HX systems where one screen can be dedicated to viewing the chart. The following documents explain how this works. Above-average computer skills are required for the download setup process.
