GPS Navigation
Altitudes associated with arrival and approach procedures are "auto-designated".
This means the system will automatically use the altitudes loaded with the arrival or
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, 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 may also be made
"non-designated" by placing the cursor over the desired altitude and pressing the CLR
Key. The altitude is now displayed only as a reference. It will not be used to give
vertical guidance. Other displayed altitudes may change due to re-calculations or
rendered invalid as a result of manually changing an altitude to a non-designated
altitude.
Large Text 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.
Small Text Altitude is not
designated to be used
in determining vertical
speed and deviation
guidance. Altitude has
been retrieved from the
navigation database
and is provided as a
reference.
