3.1.1 Orientation
Displays the radar picture and the superimposed chart in three different
ways.
- Head-Up:
The heading of own ship points upwards, the radar video is moving
with the yawing of the ship
- North-Up:
Geographic north points upwards, the radar video is stabilized with the
gyro heading
- Course-Up:
The course which exists at the instant of switch-on or re-orientation of this mode points upwards,
the radar video is thereafter stabilized with the gyro heading.
In Course-Up Mode a click with MORE on the Course-Up indicator takes over the current heading
as the new reference heading.
After switch-over and re-orientation, the target trails are not influenced; they remain visible in the
new mode.
When the ECDIS display mode is selected, the system can additonally be switched into the planning
mode. This mode is called Browse mode. See chapter B - 1.3.2 on page B-8 and section 3.1.5.
Browse mode is only supported in North-Up and Course-Up orientation. Selection of Head-Up automati-
cally switches back to the Monitoring mode.
