3. Autopilot limitation is 160ft AGL for ILS CAT 1 and 250ft AGL for the NON-precision approach, I understand that if we do not deactivate the pilot at the mentioned threshold, the FMA will display "Disconnect AP for Landing" will the vertical and lateral mode also revert to basic mode i.e. HDG & VS ?
Been a while since I was on the A320 but I would expect that it'll attempt an autoland off any ILS approach unless the topography / beam shape is so wild that it triggers the autoland warning via rad alt discrepancies or excessive deviation.
