VOBZ, on the other hand doesn't have GPA in brakets, meaning it's a geometrical projection from the THR 3 degrees upwards. Now you tell me, will you fly this approach in LNAV/VNAV mode? Most probably you'll end up flying it in LNAV monitoring the needle and going V/S or FPA on the vertical mode. Not really overlay if you ask me.
No GPA in brackets for my NDB at YPKA, approach flown the whole way in LNAV and VNAV. In the database and approved for use. Raw data monitored. We've never had overlay approaches. We went straight to dedicated GPS NPAs (now called RNAV/GNSS) when no suitable navaid approaches exist.

Yes, some of our new charts indeed now have 5-letter waypoints eg FS26Y on the YPKA VOR-Y Rwy 26.
