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 flight path guidance outside the FAF. Note that these alti-
tudes will be displayed as small light blue text.
Altitudes that have been designated for use in vertical navigation 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 flight
path 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
flight path guidance.
Small Text Altitude is not
designated to be used
in determining vertical
flight path guidance.
Altitude has been
retrieved from the
navigation database
and is provided as a
