Navigation Page, recording a trail, traveling east. Page looks like this
when the iFINDER is not navigating to a waypoint , following a route,
or backtracking a trail.
When navigating to a waypoint or following a route, the Navigation
screen looks like the one shown in the next image. Your ground speed,
track, distance, course and bearing to waypoint, are all shown digitally
on this screen.
The current cross track error is shown in the XTK box. This is the dis-
tance you are off-course to the side of the desired course line. The
course line is an imaginary line drawn from your position when you
started navigating to the destination waypoint. It's shown on the navi-
gation page as a vertical dotted line.
Lines on either side of the present position show the current cross track
error range. The default for the cross track error range is 0.20 mile. For
example, if the present position symbol touches the right cross track
error line, then you are 0.20 mile to the right of the desired course. You
need to steer left to return to the desired course. You can use the
ZIN or
ZOUT keys to change the cross track error range. A circular symbol il-
lustrating your destination (waypoint) appears on the screen as you
approach the waypoint.
Travel Time is the time that it will take to reach your destination at
your present closing speed. Arrival Time is the local time it will be
when you arrive at the destination, based upon your present closing
speed and track.
