Operator's 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 EDIT 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 EDIT 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 EDIT key, and the Skip Waypoint softkey
one time. Press the EDIT key to end this procedure. If you skip one
waypoint manually, and the CDU starts skipping more waypoints by
itself, you probably need to change your Waypoint Pass Criteria in
the CFG1 Navigate 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 time to go is greater than 99:59:59. Also,
these values are calculated by using your Waypoint Closure Velocity
(WCV), not your SOG. WCV is described in short detail in the NAV4
section which follows.
