Using the course predictor line Northstar 972
Using the course predictor line
The chart, 3D steer, and radar screens also
display a
course predictor line that indi-
cates where your vessel will be in a few
minutes if you maintain your current
course and speed. The predictor line
extends out from your vessel in the direc-
tion of your Course Over Ground. Its
length is determined by your speed and
the number of minutes you specify on the
Chart Options
screen. You can also turn the
line off.
To use the predictor line, simply select the
number of minutes you prefer the line to
represent as follows:
1. While on the Chart screen, press and hold the
CHART key to display the Chart Options
screen.
2. Select
Predictor
using the cursor pad.
3. Press
Edit

4. Use the cursor pad to display the desired line
length (in minutes).
5. Press ENTER .
Then, just watch the predictor line on the
chart or 3D steer screen to determine
where your current course will take you.
