ALONG TRACK OFFSETS
A waypoint having an “along track offset” distance from an existing waypoint can be entered into a flight plan.
Along track offset waypoints lie along the path of the existing flight plan, and can be used to make the system
reach a specified altitude before or after reaching the specified flight plan waypoint. Offset distances can be
entered from 1 to 99 nm in increments of 1 nm. Entering a negative offset distance results in an along track
offset waypoint inserted before the selected waypoint, whereas entering a positive offset distance results in an
along track offset waypoint inserted after the selected waypoint. Multiple offset waypoints are allowed.
A waypoint must be adjacent to its parent waypoint in the flight plan, so the system limits the along-track
distance to less than the length of the leg before or after the selected waypoint. If the selected waypoint is the
active waypoint, the distance is limited to less than the distance to go to the active waypoint. Assigning an along
track offset to a leg with indeterminate length is not permitted. An along track offset is not allowed at or after
the final approach fix of an approach.
An along track offset distance cannot be modified once entered. If the along track offset distance must be
changed, the existing along track offset waypoint must be deleted and a new one created with the new offset
distance.

Entering an along track offset distance:
1) Press the FPL Key to display the Active Flight Plan Page (MFD) or the Active Flight Plan Window (PFD).
2) Press 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 OFST 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 99 nm (limited by leg distances).
5) Press the ENT Key to create the offset waypoint.
6) Press the FMS Knob to remove the flashing cursor.
