adjusted by:
•Usingthe NOSE UP/DN Wheel
•Pressingthe CWS Button, hand-flying the aircraft to attain a new Airspeed Reference, then releasing the
CWS Button
NOTE: If the Selected Altitude is reached during CWS maneuvering, the Altitude Reference is not changed.
To adjust the Altitude Reference in this case, the CWS Button must be pressed again after the Selected
Altitude is reached.
VERTICAL NAVIGATION MODES (VPTH, ALTV)
NOTE: VNV is disabled when parallel track or Dead Reckoning Mode is active. Refer to the Flight Management
Section for more information on VNV flight plans.
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 when
VNV flight planning is available. Conditions for availability include, but are not limited to:
•TheselectednavigationsourceisGPS.

•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.
