FLIGHT MANAGEMENT
Entering an along track offset distance:
1)
Press the
FPL
Key to display the ‘FPL – Active Flight Plan’ Page (MFD) or the ‘Flight Plan’ Window (PFD).
2)
Push the
FMS
Knob to activate the cursor (not required on the PFD) and turn the large
FMS
Knob to highlight
the waypoint for the along track offset.
3)
Press the
ATK OFS
Softkey (MFD only); or press the
MENU
Key, highlight ‘Create ATK Offset Waypoint’, and
press the
ENT
Key.
4)
Enter a positive or negative offset distance in the range of +/ – 1 to 999 nm (limited by leg distances).
5)
Press the
ENT
Key to create the offset waypoint.
6)
Push the
FMS
Knob to deactivate the flashing cursor.
Entering a VNV altitude and along-track offset for the waypoint:
1)
Press the
¯
Key to display the ‘Direct To’ Window.
2)
Turn the large
FMS
Knob to place the cursor in the altitude field (‘VNV’ or ‘ALT’).
3)
Enter the desired altitude.
4)
Press the
ENT
Key to accept the altitude constraint; if the selected waypoint is an airport without a runway
selected, an additional choice is displayed. Turn the small
FMS
Knob to choose ‘MSL’ or ‘AGL’, and press the
ENT
Key to accept the altitude.
5)
The cursor is now flashing in offset distance field.

PARALLEL TRACK
The Parallel Track feature allows creation of a parallel course offset of 1 to 50 nm left or right of the current
flight plan. When Parallel Track is activated, the course line drawn on the map pages shows the parallel
course, and waypoint names have a lower case “p” placed after the identifier. Activation of parallel track will
apply from the current position along the flight plan until a leg that does not meet the criteria for parallel
track. Guidance will be computed to return to the original track at the beginning of that leg.
If the parallel track proposed by the offset direction and distance is not allowed by the system, the activation
prompt is displayed, but disabled.
The following will inhibit activation of a parallel track:
»
Initiating a direct-to, to the selected waypoint.
»
If an approach leg is active, the status indicates the system is unable to activate the parallel track with the
message ‘Parallel Track Unavailable Approach Leg Active’.
»
If the offset direction and distance results in an unreasonable route geometry (e.g., there is a sharp turn of
more than 120 degrees), the status indicates the system is unable to activate the parallel track because of
invalid geometry (‘Parallel Track Unavailable Invalid Route Geometry’).
»
If the active leg is not a track between two fixes (TF) or a course to a fix (DF) leg, the status indicates the
system is unable to activate the parallel track because parallel track is not available for the active leg type
(‘Parallel Track Unavailable Not Allowed for Active Leg’).
