Note: Tidal streams have a far more significant effect at lower speeds
than at higher speeds. If the tidal flow is less than 35% of the boat’s
speed, you will not notice any difference in the autopilot’s
performance in Track mode. However, you should take extra care
during manual acquisition, as follows:
•
Before you select Track mode, make sure the boat is as close as
possible to track, and the direction made good over the ground is
as close as possible to the direction of the next waypoint.
•
Make positive checks of the boat’s position at regular intervals,
especially if you are close to potential navigational hazards.
Exiting Track mode
You can return to either Auto or Standby mode from Track mode by:
•
pressing

to return to Auto mode
•
pressing
standby
to return to manual steering
Cross track error
Cross track error (XTE) is the distance between the current position
and a planned route. The autopilot receives the cross track error
information from the navigation equipment, and displays the XTE in
nautical miles (
nm
), statute miles (
SM
) or kilometres.
