Position Alignment

The position alignment feature functions to fine tune ship's position by using radar
echo target and chart material.
If position alignment is in use, the Alert 640 (ALF format: 10803) "Chart Align: Over 30
Min." is generated every 30 minutes to remind the user to align position. The alert is
automatically erased in 10 seconds.
Note: This feature is effective with the chart radar unit whose data source for FILT is
assigned the highest priority.

How to align position

If the radar echo targets' symbols are not positioned correctly on the chart, there is ei-
ther position error or gyro error or some combination of these errors.
Position may be aligned on the chart radar display
by moving own ship position or by moving radar
target position. To align position, get into the Voy-
age navigation mode, click the [Offset] button at
the top-right position on the screen. (You are asked if you want to align position; click
the [Yes] button to proceed.) Put the cursor on the correct position then click. The
amount of offset, in bearing and range, appears to the right the [Offset] button.
The latitude and longitude position indication is shown in yellow characters when the
position align feature is active.

How to cancel position alignment

The chart radar can display and output wind data in the following three formats:
Apparent: Windmeter-measured wind speed and direction.
Wind angle reference: Heading
North: True wind angle, true wind speed
Wind angle reference: True North
Theoretical: True wind angle, true wind speed
Wind angle reference: Heading
The illustration below shows wind speed and direction with given ship data.
The wind values are as shown below.
Ship information:
COG: 60°
SOG: 8.7 kn
