Navigation Page, going to a waypoint while creating a new trail.
The cross track error range is shown on the compass rose as a wide,
white, corridor enclosing the course line. The outer edges of this white
corridor represent lines that show the current cross track error range.
The default for the cross track error range is 0.20 miles.
For example, if the present position symbol touches the right cross
track error line, then you are 0.20 miles 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 depicting your destination (waypoint) appears on the
screen as you approach the waypoint, as shown on the screen in the
preceding figure.
Travel Time is the time that it will take to reach your destination at
your present closing speed. (You can also customize the time data box
to show Arrival Time instead. Arrival Time is the local time it will be
when you arrive at the destination, based upon your present closing
speed and track.)
In the preceding example figure, the driver is headed west (a 265º
track) toward a waypoint 265º (bearing) away. The cross track error
range (white corridor) is 0.20 miles either side of the course. The driver
is headed toward trail waypoint 4, which is 0.3 miles away. The vehicle
is right on course. Traveling at a speed of 8 mph, the driver will arrive
at the waypoint in 2 minutes, 17 seconds.
