VERTICAL NAVIGATION MODES (VPTH, ALTV)
NOTE: Refer to the GPS Navigation Section for more information on VNV flight plans.
NOTE: VNV is disabled when parallel track or Dead Reckoning Mode is active.
NOTE: The Selected Altitude takes precedence over any other vertical constraints.
Vertical Navigation (VNV) flight control is available for enroute/terminal cruise and descent operations any
time that VNV flight planning is available. Conditions for availability include, but are not limited to:
The selected navigation source is GPS.
A VNV flight plan (with at least one altitude-constrained waypoint) or vertical direct-to is active.
VNV is enabled (
VNV ENBL Softkey pressed on the MFD).
Crosstrack error is valid and within certain limits.
Desired/actual track are valid or track angle error is within certain limits.
The VNV Target Altitude of the active waypoint is no more than 250 ft above the current aircraft altitude.
The flight director may be armed for VNV at any time, but no target altitudes are captured during a climb.
The Command Bars provide vertical profile guidance based on specified altitudes (entered manually or loaded
from the database) at waypoints in the active flight plan or vertical direct-to. The appropriate VNV flight
control modes are sequenced by the flight director to follow the path defined by the vertical profile. Upon
reaching the last waypoint in the VNV flight plan, the flight director transitions to Altitude Hold Mode and
cancels any armed VNV modes.
