From time to time, you might drift offcourse and decide not to return to
your original course line. If you drift outside of your cross-track error
limit, you can reset your course line from your present position to the
waypoint by pressing the E key and selecting Reset XTE from the
display. This will save your autopilot from having to work hard to get
you back on course. Press the E key again to get back into'normal
display mode.
In addition, ifyou decide you want to skip this waypoint, and go on to
the next one, Press the Ekey, and the Skip Waypoint softkey one time.
Press the Ekey to end this procedure. If you skip one waypoint manu-
ally, and the CDU starts skipping more waypoints by itself, you prob-
ably need to change your Waypoint Pass Criteria in the CFGl Navi-
gate menu. Refer to the Route section of this manual for more details
about skipping waypoints.
Just as in NAVI, you will see an RL or GC symbol in the upper right
corner of the display indicating whether you are navigating under
Rhumb Line or Great Circle. This is set in the CFGl Navigate menu.
