Cross track error and course deviation angle
Navigation graph of (NAV2) screen
Use the navigation graph to check the distance and bearing to the waypoint. When the distance to WPT
is further than the range (radius) of navigation graph, the WPT locates on the circle of navigation graph.
When the distance is closer than the graph range, the WPT marking shows in the circle. The XTE bar
graph and course deviation angle bar graphs appear only when the WPT is on the circle (these graphs
are cleared in the short distance).

1. The cross track error (XTE) indication is 9.99
(nm, sm,km) maximum, and doesn't change
beyond that limit.
2. The XTE bar graph responds up to 1.00 (nm,
sm, km) deviation, and doesn't change
beyond that limit.
3. To set an XTE alarm, see the "Alarm" (page
29).
4. The course deviation angle indication is
180 degrees maximum.
The range that can be changed is as follows.
