The unit will provide course guidance only on the
inbound side of the holding pattern, however guid-
ance is provided along the entire holding pattern
via roll steering-equipped autopilots. When leav-
ing the holding pattern to re-fly the approach (or
another approach) press the PROC key to "Select
Approach?" or "Activate Approach?" as previously
described. (Or, use the direct-to key to select
another destination).

Description
Follow lateral and vertical guidance to LPV
minimums. A yellow background indicates
the current VPL and/or HPL values are not
adequate for the approach and is an early
indication that downgrading will occur if
conditions do not improve.
GPS approach identified in the database as
LNAV/VNAV. Fly to LNAV/VNAV minimums.
Non-precision GPS approach with advanced
vertical guidance. Note that some LNAV/
VNAV approaches are not yet marked in
the database 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.
Non-precision GPS approach or non-GPS
approach, such as ILS or Localizer.
Missed Approach, indicates the system is
providing missed approach integrity and
CDI full-scale deflection ±0.3 NM. This also
shows that the pilot has initiated a Missed
Approach by pressing the OBS key after
crossing the MAP.
En route, CDI full-scale deflection is 2.0 NM
or current CDI scale selection, whichever is
smaller.
Terminal, CDI full-scale deflection is 1.0 NM
or current CDI scale selection, whichever is
smaller.
Departure, indicates the system is using non-
precision approach integrity. HAL = 0.3 and
CDI full-scale deflection is 0.3 NM.
Oceanic, CDI full-scale deflection is 2.0 NM.
For LNAV+V, LNAV/VNAV, or LPV approach-
es, 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.
