9.G, as I said above, "Overlay Approaches" simply do not exist here, nor do the US rules on flying them. If an NPA is in the DB, we can use LNAV and VNAV to fly it provided we monitor the raw data info.
please have a closer look at Jeppesen plate 16-1 YPKA on lateral & vertical profile VPA is depicted in brakets (3,00) starting from FN08Y till EP08 whereas neither VOBZ bor ZMUB do have it depicted this way.
The NDB 26 at VOBZ
does have the top-of-the-drop waypoint; FN26, which is coded 3°, as shown, to the RW 26 waypoint.
Putting it another way, if the approach chart doesn't have the FMS waypoints, it's probably not going to be in the DB (all made by the same company), and guess what: we wouldn't fly it in LNAV/VNAV.
