Course Up (C-UP)
If you select a new course, the picture will reset to display the new course upwards.
The reference used for Course-Up depends upon the information available at a given
time. The system always prioritizes this information in the following order.:
1. Bearing from origin to destination, i.e. intended course.
2. Locked heading from an Autopilot.
3. Bearing to waypoint.
4. Instantaneous heading.
If heading data becomes unavailable whilst in this mode, a warning message
Note:
will be shown, the status bar indicates the Course Up in brackets and the radar uses 0°
heading in relative motion. When heading data becomes available once more, Course-
Up mode is reinstated.
To select the orientation mode:
The selected motion mode is displayed in the status bar.
