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
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.
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
cyan text.
Altitudes that have been designated for use in vertical guidance can be "un-designated"
using the CLR Key. The altitude is now displayed only as a reference. It is not used to
give vertical guidance. Other displayed altitudes may change due to re-calculations or be
rendered invalid as a result of manually changing an altitude to a non-designated altitude.
An altitude constraint is invalid if:
• Meeting the constraint requires the aircraft to climb
• Meeting the constraint requires the maximum flight path angle or maximum vertical
speed to be exceeded.
• The constraint is within a leg type for which altitude constraints are not supported
• The altitude constraint is added to the FAF of an approach that provides vertical
guidance (i.e., ILS or GPS SBAS approach) unless the aircraft is configured to accept
a FAF altitude manual designation.
• The altitude constraint is added to a waypoint past the FAF.
Entering/designating or modifying an altitude constraint:
1) Press the FPL Key on the MFD to display the 'FPL - Active Flight Plan' Page.
2) Press the FMS Knob, and turn to highlight the desired waypoint altitude
constraint.
