Hi, There are AP issues. In the HDG mode any change of source of navigation CDI button forces AP to the ROLL mode. After activating the LOC or ILS frequency, course is not automatically set to the final approach course. Instead of the LOC mode for horizontal navigation in the APR mode the VAPP is displayed when CDI is set to NAV1 or NAV2. BTW vertical navigation in GFC 700 is far best I have seen yet. Good work.
