APPROACHES Annunciation LPV LP LP +V L/VNAV LNAV+V LNAV MAPR ENR TERM DPRT OCN LOW ALT (lower window) Description Localizer Performance with Vertical guidance (LPV) approach. Fly to LPV minimums. A yellow background indicates that the approach is safe to continue but a downgrade to LNAV may occur. LP indicates Localizer Performance with no vertical guidance. LP +V indicates Localizer Performance with advisory vertical guidance. Fly LP minimums down to the MDA and missed approach location. This annunciation is available in SW Ver 5.10, or later. Lateral Navigation and Vertical Navigation (LNAV/VNAV) approach. Fly to LNAV/VNAV minimums. GPS approach using published LNAV minima. Advisory vertical guidance is provided. Lateral Navigation approach. Fly to LNAV minimums. Missed Approach indicates the system is providing missed approach integrity and CDI full-scale deflection ±0.3 NM. 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 nonprecision 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 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 annunciation will not be active when TAWS or Terrain is operational. 190-00356-01 Rev H 19
