guidance. Altitude has been retrieved
from the navigation database and is
provided as a reference.
Altitudes associated with arrival and approach procedures are not "auto-designated". This means the system
does not automatically use the altitudes loaded with the arrival or approach for giving vertical speed and
deviation guidance. Note that these altitudes are displayed as white 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 turn to 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.
Designating a procedure 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 turn to highlight the desired waypoint altitude.
3) Press the ENT Key. The altitude is now shown in blue, indicating it is usable for vertical guidance.
Altitude constraints are displayed and entered in feet mean sea level (MSL) values to the nearest hundred. An
altitude constraint in feet above ground level (AGL) format is supported for airports. When a database altitude
restriction is displayed, the G1000 allows entry of a different altitude when creating a waypoint, effectively
overriding the database restriction (only before the FAF). When a database altitude restriction of type "AT or
ABOVE" or "AT or BELOW" is activated, the system uses the "AT" portion of the restriction to define the vertical
profile.
