Parallel Track
NOTE:
En route vertical navigation is unavailable while the parallel track
function is active.
Parallel track allows you to create a parallel course offset of 1 to 99 NM to
the left or right of your current flight plan. After setting a parallel track to your
current flight plan, a magenta parallel track line will be drawn offset from the
original by the selected distance. The original course line will be drawn in gray.
The aircraft will navigate to the parallel track course line and external CDI/HSI
guidance will be driven from the parallel track.
When you reach the end of the flight plan, a message will state, “Parallel
offset terminating in X seconds.” The message will be given when the aircraft
reaches the offset distance from the end of the parallel track. This will give the
pilot sufficient time to intercept the original course.

NOTE:
In software v6.21 and earlier, graphically editing a flight plan cancels
the parallel track function.
