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.
