SECTION 1
SYSTEM OVERVIEW
Since altitudes loaded with an arrival procedure are
published only for turbojet aircraft, the altitudes are
displayed as white text indicating that the altitudes are
displayed for reference only. An arrival waypoint altitude
may be used (or “designated”) as is, or changed to a
different altitude. An altitude is designated by pressing the
FMS Knob and turning the large FMS Knob to place the
cursor on the desired altitude and pressing the ENT Key or
entering a different value and pressing the ENT Key. The
altitude will now be displayed as blue text, indicating that
the altitude is now designated to give vertical speed and
deviation guidance.
Approach waypoint altitude constraints are designated
in the same way as previously described for arrivals. These
altitudes will also be displayed as blue text after being
designated for use. Waypoint altitude constraints may
be designated 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.

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 by the
pilot. 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.
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.
Altitude is designated for use in
giving vertical speed and deviation
guidance. Altitude has been
retrieved from the navigation
database or has been entered by
the pilot and matches a published
altitude in the navigation database.
The system cannot use this altitude
in determining vertical speed and
deviation guidance.

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.
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.
To help interpret the meanings of how the altitudes are
presented, keep the following points in mind:
• When the altitude is displayed in light blue,
the system is using that altitude (designated) to
determine vertical speed and deviation guidance.
• When the altitude is displayed in white, it is not being
used by the system (non-designated) to determine
the vertical speed and deviation guidance.
• An altitude displayed as small text is an altitude that
is published in the navigation database.
• Altitudes displayed as a light blue subdued text
cannot be used in the current vertical navigation
calculations.
