5OOO
FT
Advisory altitude calculated by the system
estimating the altitude of the aircraft as it
passes over the navigation point. No white
line above or below to indicate a potential
constraint.
5OOO
FT
Altitude retrieved from the navigation
database. White line above or below
indicates the type of constraint, as shown
in the preceding figure.
These altitudes are provided as a reference,
and are not designated to be used in
determining vertical guidance.
Altitude is designated for use in
determining vertical guidance. A pencil
icon indicates manual designation or
manually edited data entry.
The system cannot use this altitude in
determining vertical guidance because of
an invalid constraint condition.
Table 5-10 Altitude Constraint Color Coding
When a procedure is loaded, the system will auto-designate (automatically enter and enable) altitude
constraints to be used for vertical guidance. An altitude constraint which has been auto-designated by the
system will be displayed as cyan text.
An altitude constraint may be manually designated for procedure waypoints and enroute waypoints by
activating and moving the cursor to the desired altitude in the active flight plan, turning the small
FMS
Knob and pressing the
ENT
Key. An altitude constraint may be manually designated only if it is available for
vertical guidance. Altitudes that are not available for vertical guidance are shown in white text and cannot be
selected by the cursor.
NOTE:
If the Final Approach Fix (FAF) is available for vertical guidance, the FAF altitude constraint may be
modified and set above or below the published FAF altitude.
For all designated altitudes, the system will automatically calculate advisory altitudes prior to the designated
altitude constraint. These advisory altitudes are not auto-designated and are displayed as white text.
Altitudes that have been designated for use in vertical guidance can be “un-designated”. Pressing the
CLR
Key with the altitude constraint highlighted in the active flight plan removes the altitude constraint
designation. The altitude will not be used for vertical guidance and the text displayed will be shown in
white. The system will recalculate advisory altitudes (white text) once any altitude constraint is designated,
modified, or un-designated.
An altitude constraint may be entered as a flight level (FL), height above mean sea level (MSL), or height
above ground level (AGL). AGL format is only available for airport waypoints.
NOTE:
All designated altitudes (cyan text) will be displayed in the active flight plan without restriction bars
regardless of what is shown on the published procedure.
NOTE:
If the Final Approach Fix (FAF) is available for vertical guidance, the FAF altitude constraint may be
modified and set above or below the published FAF altitude.
