Vertical Navigation - Garmin G1000 Pilot's Manual

VERTICAL NAVIGATION

Refer to the Appendices for VNAV Flight Planning definitions, abbreviations, and acronyms.
NOTE:
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, entered by the pilot 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 will not be in the database. In this case the altitude may
be entered manually.
When activating or loading an arrival or approach procedure into an active flight plan, the VNAV 'ALT' fields
will be populated with any altitudes that can be retrieved from the navigation database.
To help interpret the meanings of how the altitudes are presented, keep the following points in mind:
• When the altitude is displayed in light blue, the system is using that altitude to determine vertical speed
and deviation guidance.
• When the altitude is displayed in white, it is not being used by the system to determine the vertical speed
and deviation guidance.
• An altitude displayed as small text is an altitude that is published in the navigation database.
• Altitudes displayed as a light blue halftone cannot be used in the current vertical navigation
calculations.
Refer to Figure 5-71 and Table 5-3 for more detail regarding the significance of text size and color.
