VERTICAL NAVIGATION

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.
NOTE: All arrival procedure altitudes contained in
the navigation database are for turbojet aircraft
only. If necessary, alter or enter altitudes to be
consistent with the requirements of the Cessna
Nav III aircraft.
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.

Since altitudes loaded with an arrival procedure are
published only for turbojet aircraft, the altitudes are
displayed as white text indicating that the altitudes are
displayed for reference only. An arrival waypoint altitude
may be used (or "designated") as is, or changed to a
different altitude. An altitude is designated by placing the
cursor on the desired altitude and pressing the ENT Key
or entering a different value and press the ENT Key. The
altitude will now be displayed as blue text, indicating that
the altitude is now designated to give vertical speed and
deviation guidance.
Altitudes associated with an approach procedure are
"auto-designated". This means the system will automatically
use the altitudes loaded with the approach for giving vertical
speed and deviation guidance. Note that these altitudes
will be displayed as blue text up to, but not including the
FAF. The FAF will always be a "reference only" altitude and
cannot be designated.
Altitudes that have been designated for use in vertical
guidance may also be made "non-designated" by placing the
cursor over the desired altitude and pressing the CLR Key.
Other displayed altitudes may change due to re-calculations
