Garmin G1000 Diamond DA62 Pilot's Manual page 241

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 Indicator (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 G1000 allows a vertical navigation direct-to to any waypoint in the active flight plan with an altitude
constraint "designated" for vertical guidance. Selecting the VNV Direct-to Softkey on the 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 Direct-to 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.
VNV Direct-To Softkey
Activating a vertical navigation direct-to:
1) Press the FPL Key to display the Active Flight Plan Page on the MFD.
2) Press the FMS Knob to activate the cursor and turn the FMS Knob to highlight the desired waypoint.
The selected waypoint must have a designated altitude constraint (cyan number) to be used. If not,
NOTE:
the first waypoint in the flight plan with a designated altitude constraint is selected.
