The waypoint alarm will be activated when you reach the circle
or the perpendicular line - WP line alarm - crossing through the
waypoint. When “Auto waypoint shift” is set to “WP-circle” it will
override the “WP circle alarm” function.
XTE alarm - forms a corridor along the ideal track. When crossing
one of the boundaries the XTE alarm will be activated.
The alarm will automatically reset once you are inside the limits
again. The alarm distance can be set to anywhere between 0.01 and
9.99nm.
 In Route navigation the XTE alarm value can be specified for each
route leg - see section 9.2.

distances, and GREAT CIRCLE for long trips, especially when
crossing at high latitudes. COMPOSITE navigation is used when all
the legs in a route are not set to the same navigation mode.

When set to WP-circle, the system will change to the next waypoint
