Cross track error

Cross track error (XTE) is the distance between the current position and a planned track line.

Cross track errorThere are a number of reasons why you may have a cross track error (XTE), for example:

  • Pressing the track button at a position some distance from the route.

  • Course change to avoid an obstacle.

  • Waypoint arrival under certain conditions.

If the cross track error is greater than 0.3 nm, the SmartPilot will sound the Large cross track error alarm and show whether you are to the port (Pt) or starboard (Stb) of the planned track.
