ST7000 Plus Autopilot Control Unit Owner’s Handbook
• Make positive positional checks at regular intervals, especially if
navigational hazards are close by.
Cross Track Error
Cross track error (XTE) is the distance between the current position
and a planned route. This is displayed in nautical miles (nm), statute
miles (SM) or kilometres, and is taken directly from your navigator.
The Large XTE alarm sounds if the XTE exceeds 0.3 nm.
• The direction of the error is identified as Pt (port) or Stb (starboard).
• To cancel the alarm, either press standby to leave Track mode and
return to Standby mode, or press auto to return to Auto mode.
Note: If the Large Cross Track Error alarm sounds, it is usually an
indication that the cross tide is too great for the vessel’s current speed.
