Parallel Track
FEATURE REQUIREMENTS
• Active flight plan
FEATURE LIMITATIONS
• Function not available when Direct-to is active.
• Graphical editing of the active leg cancels the parallel track function
• Offset range: 1 nm to 99 nm
• Large offset values combined with certain leg types (e.g., approach) or leg geometries
(i.e., changes in track >120º) do not support parallel track
Create a parallel course offset relative to the current
flight plan. Setup controls provide offset distance and
direction setting (left of track or right of track).
TRACK COLOR
Offset Magenta
Original Gray
Once activated, a new track line appears to the
left or right of the original course line at the
specified distance. The aircraft navigates to the
offset track with external CDI/HSI guidance now
driven from the parallel track.
A graphical depiction overlays on
the map.
