The applicant is supposed to demonstrate knowledge of the differences
between nonprecision approaches (NPA), approaches with vertical guidance
(APV), and precision approaches (PA). However, there appears to be no
requirement to fly an APV even if the aircraft is equipped to do so.


Baro VNAV and LPV are both APVs, but do not meet the precision of an ILS. This
is academic for light aircraft at this time, because no approach-capable GPS
installed in light aircraft these days can do either; they can only do LNAV
(non-precision).
