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. Noteote: The selected waypoint must have a designated altitude constraint (light blue number) to be used. If not, the first waypoint in the flight plan with a designated altitude constraint is selected.
3) Select the VNV Direct-To Softkey; or press the MENU Key, highlight ‘VNV Direct-To’, 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) Press the FMS Knob to remove the flashing cursor.
Modifying the VS TGT and FPA:
1) Press the FPL Key to display the Active Flight Plan Page on the MFD.
2) Select the VNV PROF Softkey; or press the MENU Key, highlight ‘Select VNV Profile Window’, and press the ENT Key. The cursor is now located in the CURRENT VNV PROFILE box.
3) Turn the FMS Knobs as needed to edit the values..
4) Press the FMS Knob to remove the flashing cursor.
Altitudeltitude Constraints
The G1000 system can use altitude constraints associated with lateral waypoints to give guidance for vertical navigation. These altitudes are, depending on the specific instance, manually entered or retrieved from the published altitudes in the navigation database. The navigation database only contains altitudes for procedures that call for “Cross at” altitudes. If the procedure states “Expect to cross at,” then the altitude is not in the database. In this case the altitude may be entered manually.

Altitude calculated by the system estimating the altitude of the aircraft as it passes over the navigation point. This altitude is provided as a reference and is not designated to be used in determining vertical speed and deviation guidance.
Altitude has been entered manually. Altitude is designated for use in giving vertical speed and deviation guidance. Altitude does not match the published altitude in navigation database or no published altitude exists.
The system cannot use this altitude in determining vertical speed and deviation guidance because of an invalid constraint condition

Table 5-8 Altitude Constraint Size and Color Coding
Altitudes associated with arrival and approach procedures are “auto-designated”. This means the system automatically uses the altitudes loaded with the arrival or approach for giving vertical speed and deviation guidance. Note that these altitudes are displayed as blue text up to, but not including the FAF. The FAF is always a “reference only” altitude and cannot be designated, unless the selected approach does not provide vertical guidance. In this case, the FAF altitude can be designated.
Altitudes that have been designated for use in vertical guidance can be “un-designated” using the CLR Key. The altitude is now displayed only as a reference. It is not used to give vertical guidance. Other displayed altitudes may change due to re-calculations or be rendered invalid as a result of manually changing an altitude to a non-designated altitude.
Designating a waypoint altitude to be used for vertical guidance:
1) Press the FPL Key to display the Active Flight Plan Page on the MFD.
2) Press the FMS Knob and highlight the desired waypoint altitude.
3) Turn the small FMS Knob to enter editing mode.
4) Press the ENT Key. The altitude is now shown in blue, indicating it is usable for vertical guidance.
