Furuno 1824C manual Auto course-up, Perspective C-map only, North-up, Course-up

3. PLOTTER OPERATION

3.2Presentation Mode

Three types of presentation modes are provided for the plotter display: north-up, course-up and auto course-up. To change the presentation mode, press the HIDE/SHOW key followed by the MODE soft key. Each press of the key changes the presentation mode and presentation mode indication (top right-hand corner of the screen) cyclically in the sequence of North-up, Course-up and Auto course-up.

For C-map model, the sequence is North-up, Perspective, Course-up and Auto course-up when PERSPECTIVE DISPLAY is set to ON, on the CHART DETAILS menu. (See Chapter 7.)

North-up

North (zero degree) is at the top of the display and own ship is shown with a filled circle. This mode is useful for long-range navigation.

Course-up

The course-up mode is useful for monitoring ship’s progress towards a waypoint. The destination is at the top of the screen when a destination is set. When no destination is set, the course or heading is at the top of the screen at the moment the course-up mode is selected. A filled triangle marks own ship’s position.

Note: The data sentences GGA and VTG must be output from the NavNet display unit connected to the GPS navigator in order to correctly orient the own ship marker in the course-up mode on other NavNet display units.

Auto course-up

The course is at the top of screen at the moment the auto course-up mode is selected. In this mode, the current course is kept at the top of the screen when the change is within 22.5 degrees. For example, if your vessel turns larger than

22.5degrees to port or starboard, the chart display will rotate so that your course is pointing towards the top of the screen again. A filled triangle marks own ship’s position.

Perspective (C-map only)

Chart data is projected in perspective mode, for 3D simulation, during navigation.
