Sets the distance left or right from the course line you consider to
be the maximum allowable off-track error (known as cross-track
error, "XTE"). The PLOT screens will display the scaled cross-
track error distance. The NAV screens will indicate the cross-track
error in numerical format and present the cross-track error graphi-
cally scaled left or right of the course line.
Causes an alarm to sound if your position exceeds the maximum
XTE Limit defined above when Yes is selected. To disable the alarm,
select No (default) with the Change softkey.
Sets the waypoint passed determination method. There are five
methods available:
Complex:
This is the default setting. Passing the waypoint is determined by
reaching an imaginary perpendicular line. Or you can pass the
waypoint by crossing the bisector line of an acute angle (providing
you are within 0.2 NM of the waypoint) or an obtuse angle between
your present course line and the next leg of your route.
Manual:
Passing the waypoint can only be accomplished by manually skip-
ping a waypoint. Refer to the Skipping and Unpassing Waypoints
in the Route section of this manual.
This is a great way to perform station keeping maneuvering. Refer
to the Plot Screen Use Examples in the Plot section for further
details on this application.
