ALTITUDE 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.
