Basic Operation
Parallel Track (PTK)
The Parallel Track (PTK) function allows you to create a parallel course offset of 1 to 99 NM to the left or right
of your current flight plan. You must have FROM and TO waypoints defined. Parallel Track cannot be activated
if you set a course using Direct-To or if the active leg is the first leg of the departure procedure, or the Initial Ap-
proach Fix (IAF) has been passed. Attempting to activate Parallel Track with these conditions results in the mes-
sage “Cannot Activate Parallel Track for Current Leg.” Choose Left or Right of the current course, and the offset
distance. When Parallel Track is activated, the course line drawn on the Map pages will show the parallel course,
a PTK annunciation will be shown in the lower left corner of the display, and waypoint names will have a lower
case “p” before or after their identifier. Using Direct-To, loading an approach, holding pattern, or editing and
executing your flight plan will automatically cancel Parallel Track. Parallel track is cancelled if a course change
occurs greater than 120° or the parallel tracks overlap as a result of the course change.
