12 Set up navigation
You can make the following changes to the navigation options. These changes are
global, meaning that they'll be applied to all the Chart screens.
These navigation options affect the radar, 3D Chart, 3D Steer, position information
and instrument applications, as well as charting.
You can:
•
select the bearing mode (True or Magnetic)
•
select the variation source (Automatic or Manual)
•
set the manual variation (degrees)
•
select the format for position data (Degrees/Minutes, or
Degrees/Minutes/Seconds)
•
set the look ahead distance (as a percentage value)
•
set the centre circle distance (as a percentage value)
•
set the amount of time represented by the length of the course predictor line
(one to 60 minutes)
•
set the angle delay that triggers the chart to reposition (as a degree value)
•
set the waypoint arrival distance (0.01 through 10)
•
select whether you want the 8000i to continue navigating at the route end
(Stop Navigating, or Keep Navigating)
12.1 Select the bearing mode
You can use the bearing mode to specify whether your bearings display as True
North or Magnetic North. The 8000i will display heading and bearing information
with a suffix of T (True North) or M (Magnetic North) to show the bearing mode
that is selected.
If you prefer to view:
•
magnetic bearings and have the 8000i information match with a magnetic
steering compass or hand bearing compass, select Magnetic North.
•
true bearings where everything is referenced to True North for simplicity,
select True North. If you select True North and have a compass that outputs
True North (such as a Gyro or GPS compass), the 8000i will calculate the
magnetic bearings by applying the magnetic variation. The magnetic variation
is obtained automatically from the GPS (unless you select Manual Variation
mode, in which case the manual variation is applied).
In some locations, such as close to the North or South poles, you may need to
change the variation source to manual and then specify the amount of magnetic
variation in your area (see "Set the manual variation" page 88)
To select the bearing mode:
1. Select
Display.
2. Select
Setup from the control panel.
3. Select
+ Navigation to show a list of position specification options.
