1.11 How to Enter Heading

Heading can be entered manually or automatically. Heading data is checked for integ-

rity (see section 18.7 for details), and the data is judged as [Passed], [Doubtful] or

[Failed]. The integrity check results appear on the [HDG] page, shown below. (The re-

sults do not appears when the TCS is engaged.)

Passed (green): Data is available for comparison and data is normal.

Doubtful (yellow): Data is not available for comparison, but data is normal.

Failed (red): Data may or may not be available for comparison, and data is abnormal.

Note: If there is only one gyro connected to the ECDIS, heading data is compared to

COG from GPS. When the speed is five knots or less, and COG is unstable when it is

compared to heading data, the message “Doubtful” appears for heading data. When

the ship’s speed becomes greater than 10 knots and COG stabilizes, the message

disappears after a short while.
