Parallel Track
Offset
This function allows you to create a parallel course
offset to the left or right from your current flight plan
from 0.1 to 20.0 nm. You must have FROM and TO
waypoints defined. Parallel Track cannot be activated
if you set a course using Direct-To. Transitions
between future flight plan legs cannot have turns
greater than 120 degrees. You select to place Parallel
Track “In Use” or to put it on “Standby,” choose Left
or Right of the current course, and the offset distance.
The PTK annunciator (if installed) will turn on when
Parallel Track is enabled.
When Parallel Track is selected, the course line
drawn on the Map pages will show the parallel
course. If the Hold function is used when Parallel
Track is selected, the Hold waypoint will be the
phantom waypoint on the parallel offset, not the
actual waypoint. Using Direct-To, loading an
approach, or editing your flight plan will
automatically cancel Parallel Track. A series of turns,
even if less than 120°, is not allowed if the “inside”
parallel tracks would overlap.
