3.1 Operation in Track Mode
Track mode is used to maintain a track between two waypoints
created on a GPS, Decca, or Loran navigation system. The autopilot
will then compute any course changes to keep your boat on track,
automatically compensating for tidal streams and leeway.
The autopilot can receive cross track error (the distance your vessel
is from a planned track) from a SeaTalk navigation instrument or
chartplotter
Track mode is selected by pressing the TRACK key, but can only be
selected in Auto mode. You can return to either Auto or Standby
from Track as follows:
• Press AUTO to leave Track mode and return to Auto mode.
• Press STANDBY to leave Track mode and return to manual
steering.
Initiating Track Mode
When initiating Track mode, the track can be acquired in one of two
ways:
• Automatic acquisition – when cross track error and bearing to
waypoint data are available
• Manual acquisition – when cross track error is the only available
data
