Navigate Operation & Installation Manual
From time to time, you might drift off course 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, if you decide you want to skip this waypoint, and go on to
the next one, Press the
E key, and the Skip Waypoint softkey one time.
Press the E key 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 CFG1 Navi-
gate menu. Refer to the Route section of this manual for more details
about skipping waypoints.
Just as in NAV1, 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
CFG1 Navigate menu.
NAV 3 - Expanded Navigation Information
Navigate screen 3 has four windows. The upper left window is a
smaller version of
NAV2 . Please read the previous section for a de-
tailed description of this window. The two windows below this one
indicate the current date, time and the ETA to the end of your route for
the time zone currently entered. The date and time format is set in the
CFG1 Time menu. The ETA and TTG (in the right hand window) are
filtered over time, so allow the filtering to settle when you first make a
course or speed change. The filter time is controlled in the
RTE1 ETA
Setup screen. The Time-To-Go (TTG) value on the bottom of the right
hand window expands from HH:MM:SS to HHHH:MM:SS when the
