Sam,


VLOC is only for ILS and LOC, not RNAV



I know. However, procedure activation is treated as standard in the
manual, contrary to what you alluded to. There is no mention of
"automatic activation" I could find. Could you kindly point me to it?


No, there is no approach activation for ILS or LOC. Approach
activation, as defined for *RNAV* occurs 2 miles from the FAF. When you
select a LOC or ILS, you instead receive an advisory message cautioning
you that RNAV is for monitoring only.
