Speed is the velocity you are making over the ground. If you wanted,
you could customize the Speed window to display Closing Speed in-
stead. Closing Speed is also known as velocity made good.
It is the speed you are making toward the waypoint. Track is the head-
ing or the current direction you are traveling. Bearing is the direction
of a line-of-sight from your present position to the destination. No mat-
ter what direction you are steering, the Bearing window shows the
compass direction straight to the destination from your location at the
moment. Distance shows how far it is to the waypoint you are navigat-
ing toward.
The Off Course window shows the current cross track error. This shows
the distance 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. The course line is shown
on the Navigation Page screen and the Map Page screen as a dotted line.
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 when approach the waypoint, as shown on the screen in the fol-
lowing 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 window 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.
