5.7 VERTICAL NAVIGATION

The system supports vertical path guidance and altitude constraints for the following leg types: AF,
NOTE:
CD, CF, CI, CR, DF, FC, FD, PI, RF, and TF. Altitude constraints are not retained in stored flight plans.
The system Vertical Navigation (VNV) feature provides vertical profile guidance during the enroute and terminal
phases of flight. Guidance based on specified altitudes at waypoints in the active flight plan or to a direct-to
waypoint is provided. It includes vertical path guidance to a descending path, which is provided as a linear
deviation from the desired path. The desired path is defined by a line joining two waypoints with specified
altitudes or as a vertical angle from a specified waypoint/altitude. The vertical waypoints are integrated into the
active flight plan. Both manual and autopilot-coupled guidance are supported.
