low background indicates that the approach
is safe to continue but a downgrade to LNAV
may occur.
LP LP indicates Localizer Performance with no
vertical guidance.
L/VNAV Lateral Navigation and Vertical Navigation
(LNAV/VNAV) approach. Fly to LNAV/VNAV
minimums.
LNAV+V Non-precision GPS approach with advisory
vertical guidance. Note that some LNAV/VNAV
approaches are not yet marked in the data-
base as such and will show up as LNAV+V. If
the chart shows the approach as LNAV/VNAV,
it can be flown to LNAV/VNAV minimums.
LNAV Lateral Navigation approach. Fly to LNAV

full-scale deflection ±0.3 NM.
ENR En route, CDI full-scale deflection is 2.0 NM
or current CDI scale selection, whichever is
smaller.
TERM Terminal, CDI full-scale deflection is 1.0 NM
or current CDI scale selection, whichever is

(lower window)
For LNAV+V, LNAV/VNAV, or LPV approaches,
the LOW ALT annunciation indicates the
aircraft’s estimated height is lower than the
Final Approach Waypoint height by more than
the current VPL plus 50 meters. This annuncia-
tion will not be active when TAWS or Terrain is
operational.
