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 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.
