RNAV Approaches?
-
Can the aircraft fly an RNAV approach using the FMS? KSAN does not have ILS on RW27, only 9. And I'm not confident I can do this one visually.

Yes it can as long as you have the FMC enabled in the 146. Check the charts for the RNAV RWY27 there are two sets of minima. One for LP one for LNAV. Your 146 can only do LNAV (lateral navigation) not VNAV (vertical navigation) so you have to chose the higher minima of 760 feet LNAV option. You set the aircraft to follow the LNAV waypoints but you still have to manually descend the aircraft (no pressing approach button like modern aircraft). RNAV (or RNP) is not considered a precision approach so they have higher minimum descent altitudes than an ILS - I see there is a localiser approach to that runway so you could use that as an option and you would have a lower decision height of 680 feet if the weather was bad.
