En Route Vertical Navigation
WARNING
Do not rely solely on VNAV guidance when navigating horizontally and
vertically around user-defined airports. It is the pilot's responsibility to ensure
separation from terrain and obstacles during an approach to a user-defined
airport.
FEATURE REQUIREMENTS
•
Enablement by the installer
•
Baro-corrected altitude source
FEATURE LIMITATIONS
The following flight plan waypoints do not allow altitude constraints:
•
Legs containing headings
•
Legs that terminate at an altitude (e.g., a climb to 1,800 ft before making a turn and
proceeding direct to fix)
Storing a flight plan in the catalog removes its altitude constraints.

Utilities
VNAV
Annunciations display within 60 seconds of the top or bottom of descent.
A "Vertical Track" aural message plays at 60 seconds from the top of descent.
VNAV Functions
•
Presents vertical path guidance along the descent as either a line joining two
waypoints with specified altitudes or a desired linear vertical path (i.e., the
vertical angle from the specified waypoint or altitude)
•
Integrates vertical waypoints into the active flight plan
•
Supports both manual and autopilot coupling
For installation details related to en route vertical navigation, consult the AFMS.

Create a vertical navigation (VNAV) path with multiple altitude
constraints in the flight plan.
The vertical navigation (VNAV) feature provides
vertical profile guidance during the descent phase
of flight. Guidance is based on altitude constraints
associated with lateral waypoints in the active flight
plan.
This feature is also accessible via the Active Flight
Plan menu (Home > Flight Plan > Menu > VNAV).
