Canceling vertical navigation results in vertical deviation (V DEV), vertical speed required (VS REQ), and time
to top of descent/bottom of descent (TIME TO TOD/BOD) going invalid. The Vertical Deviation Indicator (VDI)
and Required Vertical Speed Indication (RVSI) on the PFD are removed, and the V DEV, VS REQ, and TIME TO
TOD items displayed in the CURRENT VNV PROFILE box are dashed. VNV remains disabled until manually
enabled. Vertical guidance in reversionary mode can only be enabled for a direct-to waypoint.
The system allows a vertical navigation direct-to to any waypoint in the active flight plan with an altitude
constraint “designated” for vertical guidance. Pressing the VNV ¯ Softkey on the FPL – ACTIVE FLIGHT
PLAN Page allows the flight plan to be flown, while vertical guidance based on the altitude constraint at the VNV
direct-to waypoint is provided. The altitude change begins immediately and is spread along the flight plan from
current position to the vertical direct-to waypoint, not just along the leg for the direct-to waypoint. A direct-to
with altitude constraint activated by pressing the ¯ Key also provides vertical guidance, but would bypass
flight plan waypoints between the current position in the flight plan and the direct-to waypoint. A top of descent
(TOD) point is computed based on the default flight path angle; descent begins once the TOD is reached.

Activating a vertical navigation direct-to:
1) Press the FPL Key on the MFD to display the FPL – ACTIVE FLIGHT PLAN Page.
2) Push the FMS Knob to activate the cursor and turn the FMS Knob to highlight the desired waypoint.
NOTE: The selected waypoint must have a designated altitude constraint (cyan number) to be used. If not,
the first waypoint in the flight plan with a designated altitude constraint is selected.
3) Press the VNV ¯ Softkey; or press the MENU Key, highlight ‘VNV ¯’, and press the ENT Key. An ‘Activate
vertical Direct-to to: NNNNNFT at XXXXXX?’ confirmation window is displayed.
4) Press the ENT Key. Vertical guidance begins to the altitude constraint for the selected waypoint.
5) Push the FMS Knob to remove the flashing cursor.
