I have been struggling to find information in the FCOM, FCTM and in the forums that fully address the capabilities and limitation of the RNAV approach functions in the 777. I have no problem flying CAT III ILS Autoland approaches but I want to know if the autpilot will also fly an RNAV GPS approach and to what minimums, is it possible to fly an Autoland RNAV apporach, is this even possible or make sense?
Also I would like to make sure I understand the requirements, in terms of cockpit setup, to complete say an RNAV GPS apporach to LPV mins. For example the RNAV (GPS) Y RWY1C to LPV mins into KIAD.
Thanks for any help or references.
