Altitude Constraints
Altitude constraints are either entered manually into the active flight plan, or
automatically retrieved from the published altitudes in the navigation database.
GTN automatically uses altitudes loaded with arrival and approach procedures
(up to and including the FAF) for computing vertical deviation guidance.
ALTITUDE CONSTRAINT INDICATIONS
Dual values annunciate when the aircraft needs to cross between two altitudes.
Constraint values display in MSL or flight level (FL). Constraints at airports may be
specified as MSL or AGL.
Examples:
Altitude constraints loaded from the database are jet altitudes. Some adjustment
may be necessary for other types of aircraft. For the adjustment procedure,
refer to the published chart.
COLOR DEFINITIONS
White Altitude is for reference only.
Cyan
GTN honors the constraint for
vertical guidance when the
VNAV function is active.
When the VNAV function is active,
altitudes may be accompanied by
one or two altitude restriction
bars. The position of the value
(above or below the bar, or
between two bars) denotes the
required aircraft altitude relative
to that constraint.
Cross at or Above 5,000 ft Cross at or Below 5,000 ft
Cross at 5,000 ft
Cross Between 5,000 ft and 6,000 ft
