Annunciation

Description

LPV

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. 

L/VNAV

GPS approach identified in the database as 
LNAV/VNAV. Fly to LNAV/VNAV minimums. 

LNAV+V

Non-precision GPS approach with advanced 
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

Non-precision GPS approach or non-GPS ap-
proach, such as ILS or Localizer. 

MAPR

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. 

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 
smaller. 

DPRT

Departure, indicates the system is using non-
precision approach integrity. HAL = 0.3 and 
CDI full-scale deflection is 0.3 NM. 

OCN

Oceanic, CDI full-scale deflection is 2.0 NM. 

LOW ALT

(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.
