Hoping someone can answer this from actual experience on a HDX. Has anyone been able to "arm" VNAV on a GPS approach (when vert is provided on the approach) or "arm" for an ILS in either case when there is NO GS indication? My ability to arm only works after a GS is indicated. The instructions are difficult and actually contradict in two places. I've flown with 4 different planes all with vertical guidance (all with Garmin 430W, 530W, Avidyne 440 and 650) and none will allow arming prior to GS indication.
Thanks
Dan
