I have been vectored on to an RNAV final approach course inside of the IAF or IF where the LPV GS begins (always on an LNAV, as I had no LPV capability before, but now I do). In these cases, it means that I will likely become established well above the LPV GS for that point. If I arm the GPSV approach during the vectors, will the GRT wait until it is within 2 dots of horizontal deviation before it attempts to capture the GS? The manual says that it performs this way for the ILS, but I wasn't sure if that would be true for the GPSV.
Also, I have read that on an ILS, I do not want to press the execute button, after arming, until inbound on the approach course (i.e. after procedure turns, etc.). Does this apply to a GPSS/GPSV approach? I would assume that I would not need to worry, as it is just following roll commands and not capturing a course, but I suppose I could be betting headings to the IAF. Still, it would seem that I am not capturing a course, but following waypoint sequencing and getting roll steering commands.
Thanks for your help here. I have just installed a 430W and thinking ahead to using some of these features.
