Just one more clarification Arko, since RNAV approaches there ain't no "precision" or "non-precision" approaches any more. RNAV approaches vary in their precision so that terminology is gone. In Sydney QF have been operating commercial RNAV approaches to autoland (called GLS which is GBAS assisted GNSS updated RNAV). RNP-AR approaches vary in their precision depending on the RNP figure used (a tighter RNP gives a lower minima). VOR and NDB approaches flown in LNAV/VNAV are just as precise as RNP-AR approaches (if they are coded to the RWY threshold). In fact, in QF the approach aid doesn't even have to be working.
