Note: The closer the boat is to the correct heading and track when
you press
track, the quicker the autopilot will bring the boat onto the
new course. If the boat is more than 0.3 nm from the track, the Large
Cross Track Error warning will sound (see page 19).
Exiting Track mode
You can exit Track mode and return to Auto or Standby mode by:

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.
If the cross track error is greater than 0.3 nm, the ST7001+ will sound
the Large Cross Track Error warning and show whether you are to the
port
(Pt) or starboard (Stb) of the planned track.
